1.5.0 Chia blockchain 2022-7-26

Added

Added derivation index information to the Wallet UI to show the current derivation index height
Added section in Settings to allow the user to manually update the derivation index height in order to ensure the wallet finds all the coins
Added a tooltip for users to understand why their CAT balance has changed as new CAT2 tokens get re-issued
There is now a blockchain_wallet_v2_r1_*.sqlite DB that will be created, which will sync from 0 to look for CAT2 tokens. This preserves a copy of your previous wallet DB so that you are able to look up previous transactions by using an older wallet client
Extended min_coin to RPC calls, and CLI for coin selection
Show DID in the offer preview for NFTs
Added wallet RPCs (get_derivation_index, update_derivation_index) to enable the GUI, and CLI to report what the current derivation index is for scanning wallet addresses, and also allows a user to move that index forward to broaden the set of addresses to scan for coins

Changed

Changed the DID Wallet to use the new coin selection algorithm that the Standard Wallet, and the CAT Wallet already use
Changed returning the result of send_transaction to happen after the transaction has been added to the queue, rather than it just being added to the mempool.
Increased the priority of wallet transactions vs full node broadcasted transactions, so we don't have to wait in line as a wallet user
Deprecated the -st, --series-total and -sn, --series-number RPC and CLI NFT minting options in favor of -ec, --edition-count and -en, --edition-number to align with NFT industry terms
When creating a DID profile, a DID-linked NFT wallet is automatically created
Update chia wallet take_offer to show NFT royalties that will be paid out when an offer is taken
Added a parameter to indicate how many additional puzzle hashes create_more_puzzle_hashes should create

Fixed

Fixed [CVE-2022-36447] where in tokens previously minted on the Chia blockchain using the CAT1 standard can be inflated in arbitrary amounts by any holder of the token. Total amount of the token can be increased as high as the malicious actor pleases. This is true for every CAT1 on the Chia blockchain, regardless of issuance rules. This attack is auditable on-chain, so maliciously altered coins can potentially be "marked" by off-chain observers as malicious.
Fixed issue that prevented websockets from being attempted if an earlier websocket failed
Fixed issue where test_smallest_coin_over_amount did not work properly when all coins were smaller than the amount
Fixed a performance issue with knapsack that caused it to keep searching for more coins than could actually be selected. Performance with 200k coins:
- Old: 60 seconds
- New: 0.78 seconds
Fixed offer compression backwards compatibility
Fixed royalty percentage check for NFT0 NFTs, and made the check for an offer containing an NFT more generalized
Fixed timing with asyncio context switching that could prevent networking layer from responding to ping

1.3.4 Chia blockchain 2022-4-19

Added

Creating an offer now allows you to edit the exchange between two tokens that will auto calculate either the sending token amount or the receiving token amount
When making an offer, makers can now create an offer including a fee to help get the transaction into the mempool when an offer is accepted
Implemented chia rpc command
New RPC get_coin_records_by_hint - Get coins for a given hint (Thanks @freddiecoleman)
Add maker fee to remaining offer RPCs

Add /get_stray_cats API for accessing unknown CATs

Changed

Left navigation bar in the GUI has been reorganized and icons have been updated
Settings has been moved to the new left hand nav bar
Token selection has been changed to a permanent column in the GUI instead of the drop down list along
Manage token option has been added at the bottom of the Token column to all users to show/hide token wallets
Users can show/hide token wallets. If you have auto-discover cats in config.yaml turned off, new tokens will still show up there, but those wallets won’t get created until the token has been toggled on for the first time
CATs now have a link to Taildatabase.com to look up the Asset ID
Ongoing improvements to the internal test framework for speed and reliability.
Significant harvester protocol update: You will need to update your farmer and all your harvesters as this is a breaking change in the harvester protocol. The new protocol solves many scaling issues. In particular, the protocol supports sending delta changes to the farmer - so for example, adding plots to a farm results in only the new plots being reported. We recommend you update your farmer first.
Updated clvm_tools to 0.4.4
Updated clvm_tools_rs to 0.1.7
Changed code to use by default the Rust implementation of clvm_tools (clvm_tools_rs)

Fixed typo "log_maxbytessrotation" in initial-config (@skweee made their first contribution!)

Added

Added checks to ensure wallet address prefixes are either xch or txch.
Added a better TLS1.3 check to handle cases where python is using a non-openssl TLS library.

Changed

Update the database queries for the block_count_metrics RPC endpoint to utilize indexes effectively for V2 DBs.
Several improvements to tests.

1.3.0 Chia blockchain 2022-3-07

Added

CAT wallet support - add wallets for your favorite CATs.
Offers - make, take, and share your offers.
Integrated lite wallet sync - to get you synced up faster while your full node syncs.
Wallet mode - Access just the wallet features to make and receive transactions.
Farmer mode - All your farming tools, and full node, while getting all the benefits of the upgraded wallet features.
New v2 DB - improved compression for smaller footprint (the v2 DB is created alongside the v1 DB. Please be sure to have enough disk space before executing the DB upgrade command).
Key derivation tool via CLI - lets you derive wallet addresses, child keys, and also search your keys for arbitrary wallet addresses/keys.
Lite wallet data migration - CAT wallets you set up and your offer history will be carried over.
The farmer will report version info in User-Agent field for pool protocol (Thanks @FazendaPool).
Added new RPC, get_version, to the daemon to return the version of Chia (Thanks @dkackman).
Added new config.yaml setting, reserved_cores, to specify how many cores Chia will not use when launching process pools. Using 0 will allow Chia to use all cores for process pools. Set the default to 0 to allow Chia to use all cores. This can result in faster syncing and better performance overall especially on lower-end CPUs like the Raspberry Pi4.
Added new RPC, get_logged_in_fingerprint, to the wallet to return the currently logged in fingerprint.
Added new CLI option, chia keys derive, to allow deriving any number of keys in various ways. This is particularly useful to do an exhaustive search for a given address using chia keys derive search.
Div soft fork block height set to 2,300,000.
Added the ability to add an optional fee for creating and changing plot NFTs.
Added multiprocessing_start_method: entry in config.yaml that allows setting the python start method for multiprocessing (default is spawn on Windows & MacOS, fork on Unix).
Added option to "Cancel transaction" accepted offers that are stuck in "pending".

Changed

Lite wallet client sync updated to only require 3 peers instead of 5.
Only CATs from the default CAT list will be automatically added, all other unknown CATs will need to be manually added (thanks to @ojura, this behavior can be toggled in config.yaml).
New sorting pattern for offer history - Open/pending offers sorted on top ordered by creation date > confirmation block height > trade id, and then Confirmed and Cancelled offers sorted by the same order.
When plotting multiple plots with the GUI, new items are taken from the top of the list instead of the bottom.
CA certificate store update.
VDF, chiapos, and blspy workflows updated to support python 3.10 wheels.
We now store peers and peer information in a serialized format instead of sqlite. The new files are called peers.dat and wallet_peers.dat. New settings peers_file_path and wallet_peers_file_path added to config.yaml.
CLI option chia show will display the currently selected network (mainnet or testnet).
CLI option chia plots check will display the Pool Contract Address for Portable (PlotNFT) plots.
Thanks to @cross for adding the ability to resolve IPv6 from hostnames in config.yaml. Added new config option prefer_ipv6 to toggle whether to resolve to IPv6 or IPv4. Default is false (IPv4).
The default timeout when syncing the node was increased from 10 seconds to 30 seconds to avoid timing out when syncing from slower peers.
TLS 1.2 is now the minimum required for all communication including peer-to-peer. The TLS 1.2 allowed cipher list is set to: "ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256".
In a future release the minimum TLS version will be set to TLS 1.3. A warning in the log will be emitted if the version of openssl in use does not support TLS 1.3. If supported, all local connections will be restricted to TLS 1.3.
The new testnet is testnet10.
Switch to using npm ci from npm install in the GUI install scripts.
Improved sync performance of the full node by doing BLS validation in separate processes.
Default log rotation was changed to 50MiB from 20MiB - added config.yaml setting log_maxbytesrotation to configure this.
Thanks to @cross for an optimization to chiapos to use rename instead of copy if the tmp2 and final files are on the same filesystem.
Updated to use chiapos 1.0.9.
Updated to use blspy 1.0.8.
Implemented a limit to the number of PlotNFTs a user can create - with the limit set to 20. This is to prevent users from incorrectly creating multiple PlotNFTs. This limit can be overridden for those users who have specific use cases that require more than 20 PlotNFTs.
Removed the option to display "All" rows per page on the transactions page of the GUI.
Updated the background image for the MacOS installer.
Changed the behavior of what info is displayed if the database is still syncing.
- It should not be expected that wallet info, such as payout address, should not reflect what their desired values until everything has completed syncing.
- The payout instructions may not be editable via the GUI until syncing has completed.

Fixed

Offer history limit has been fixed to show all offers now instead of limiting to just 49 offers.
Fixed issues with using madmax CLI options -w, -G, -2, -t and -d (Issue 9163) (thanks @randomisresistance and @lasers8oclockday1).
Fixed issues with CLI option –passhrase-file (Issue 9032) (thanks @moonlitbugs).
Fixed issues with displaying IPv6 address in CLI with chia show -c.
Thanks to @chuwt for fix to looping logic during node synching.
Fixed the chia-blockchain RPM to set the permission of chrome-sandbox properly.
Fixed issues where the wallet code would not generate enough addresses when looking for coins, which can result in missed coins due to the address not being checked. Deprecated the config setting initial_num_public_keys_new_wallet. The config setting initial_num_public_keys is now used in all cases.
Thanks to @risner for fixes related to using colorlog.
Fixed issues in reading the pool_list from config if set to null.
Fixed display info in CLI chia show -c when No Info should be displayed.
Thanks to @madMAx43v3r for fixes in chiapos related to a possible race condition when multiple threads call Verifier::ValidateProof.
Thanks to @PastaPastaPasta for some compiler warning fixes in bls-signatures.
Thanks to @random-zebra for fixing a bug in the bls-signature copy assignment operator.
Thanks to @lourkeur for fixes in blspy related to pybind11 2.8+.
Thanks to @nioos-ledger with a fix to the python implementation of bls-signatures.
Thanks to @yan74 for help debugging a race condition writing to config.yaml during beta.
Fixed issue where the DB could lose the peak of the chain when receiving a compressed block.
Fixed showing inbound transaction after an offer is cancelled.
Fixed blockchain fee "Value seems high" message showing up when it shouldn't.
Bugs in pool farming where auth key was being set incorrectly, leading to invalid signature bugs.
Memory leak in the full node sync store where peak hashes were stored without being pruned.
Fixed a timelord issue which could cause a few blocks to not be infused on chain if a certain proof of space signs conflicting blocks.

Known Issues

When you are adding plots and you choose the option to “create a Plot NFT”, you will get an error message “Initial_target_state” and the plots will not get created.
- Workaround: Create the Plot NFT first in the “Pool” tab, and then add your plots and choose the created plot NFT in the drop down.
When you close the Chia app, regardless if you are in farmer mode or wallet, the content on the exit dialog isn’t correct.
If you start with wallet mode and then switch to farmer mode and back to wallet mode, the full node will continue to sync in the background. To get the full node to stop syncing after switching to wallet mode, you will need to close the Chia and relaunch the Chia app.
Wallets with large number of transactions or large number of coins will take longer to sync (more than a few minutes), but should take less time than a full node sync. It could fail in some cases.
Huge numbers cannot be put into amount/fee input for transactions in the GUI.
Some Linux systems experience excessive memory usage with the value default/python_default/fork configured for multiprocessing_start_method:. Setting this value to spawn may produce better results, but in some uncommon cases, is know to cause crashes.
Sending a TX with too low of a fee can cause an infinite spinner in the GUI when the mempool is full.
- Workaround: Restart the GUI, or clear unconfirmed TX.
Claiming rewards when self-pooling using CLI will show an error message, but it will actually create the transaction.

1.2.11 Chia blockchain 2021-11-4

Added

Farmers rejoice: today's release integrates two plotters in broad use in the Chia community: Bladebit, created by @harold-b, and Madmax, created by @madMAx43v3r. Both of these plotters bring significant improvements in plotting time. More plotting info here.
This release also includes several important performance improvements as a result of last weekends "Dust Storm", with two goals in mind: make sure everyone can farm at all times, and improve how many transactions per second each node can accept, especially for low-end hardware. Please know that these optimizations are only the first wave in a series of many over the next few releases to help address this going forward. While the changes we have implemented in this update may not necessarily solve for every possible congestion scenario, they should go a long way towards helping low-end systems perform closer to expectations if this happens again.
Performance improvements for nodes to support higher transaction volumes, especially for low powered devices like RaspBerry Pi. Full details at #9050.
- Improved multi-core usage through process pools.
- Prioritized block validation.
- Added transaction queues for more efficient handling of incoming transactions.
- Increased BLS pairing cache.
Integrated the Bladebit plotter to CLI and GUI. Thanks @harold-b for all your hard work on this, and welcome again to the Chia Network team!
Added the Madmax plotter to CLI and GUI. Thanks @madMAx43v3r for your support!
Added option to configure your node to testnet using to chia init --testnet.

Changed

Improved the wallet GUI's startup loading time by loading the default private key's fingerprint.
Upgraded from clvm_rs 0.1.14 to 0.1.15.

Fixed

Minor verbiage and syntax changes in CLI and GUI.
Partial version to fix launcher name definition.
Fix harvester plot loading perfomance issues.
Fixed a packaging failure when passphrase is being used. Thanks @ForkFarmer for reporting this defect.
Fixed launcher name definition, which resolved an issue for some users in which wallet-node couldn't sync.
Fixed a bug in the GUI that prevented some users from switching their plotNFT.

Known Issues

PlotNFT transactions via CLI (e.g. chia plotnft join) now accept a fee parameter, but it is not yet operable.

1.2.10 Chia blockchain 2021-10-25

We have some great improvements in this release: We launched our migration of keys to a common encrypted keyring.yaml file, and we secure this with an optional passphrase in both GUI and CLI. We've added a passphrase hint in case you forget your passphrase. More info on our wiki. We also launched a new Chialisp compiler in clvm_tools_rs which substantially improves compile time for Chialisp developers. We also addressed a widely reported issue in which a system failure, such as a power outage, would require some farmers to sync their full node from zero. This release also includes several other improvements and fixes.

Added

Added support for keyring migration from keychain, and the addition of passphrase support. Learn more at our wiki.
Enabled experimental use of a new Chialisp compiler in clvm_tools_rs in chia-blockchain, which is off by default, and substantially improves compile time.
Added Windows PowerShell scripts to support installation from source.
Added a test to check that we don't reorg subslots unless there is a new peak.
Added harvester info to farmer logging.
Add 'points found 24h' to CLI reporting.
Added an alternative to pkm_pairs_for_conditions_dict() which is a bit more straightforward and returns the public keys and messages in the forms we need them to validate them.
Added ability to see unopenable plots at the end of plots check.
Added Program.at utility function.

Changed

Truncate points_[found,acknowledged]_24h to 24 hours at each signage point.
Improved reliability of test_farmer_harvester_rpc.py, by increasing the interval between harvester checks, which should avoid spamming logs with excessive plot refreshing and cache updates.
Thanks @cross for change that allows using IPv6 address in config.yaml for remote harvesters and other chia services.
Change to stop creating unused indexes in block_records and full_blocks tables.
Removed unnecessary index in CoinStore & add additional benchmarks.
Changed db_sync setting to default to FULL. In a prior release, this setting caused some users to have to resync their full node from zero if the node went offline, such as in a power outage. Users can change this to OFF in config.yaml.
Updated the coin_store benchmark to enable synchronous mode when talking to the DB, since that's the default now, and improves the output a bit.
Updated the old comment on chia/util/streamable.py with newer developer documentation.
Minor GUI changes based on community feedback.
Thanks @jack60612 for your help in improving our GUI code, including upgrading to electron 13, migration to electron remote, updating the latest dependencies, and more.

Fixed

Corrected a super-linter name typo to GitHub
Thanks @sharjeelaziz for correcting our typo in your name. Our apologies for the error!
In macOS builds, changed the export value of NOTARIZE to fix some build failures.
Fix log output for duplicated plots.
Removed a flaky mtime check for plots that resolved an issue where file_path.stat() shows multiple copies of plots and slows performance of the farmer. Thanks @timporter for the assist on this one.
Thanks @jcteng for fixing a bug on the Chia DID wallet that showed 'mojo:'' instead of 'mojo'.

1.2.9 Chia blockchain 2021-10-01

Changed

Changed "About" section in client to indicate correct release version.

1.2.8 Chia blockchain 2021-09-30

Added

Added RPC updates to support keyring migration and to support adding a passphrase for wallets in an upcoming release.
Added plot memo caching in PlotManager, speeding initial loading and cached loading, by enabling harvester to save the parsed plot memo on disk on shutdown, then load it back into memory on startup so that it can skip key parsing calculations for all already known plots.
Added a debug option to log all SQL commands.
Added support for DID, our decentralized identity solution, as a building block toward Chia's broader set of DID capabilities.
Thanks @olivernyc for the addition of a query in CoinStore to special case height 0 to avoid querying all unspent coins.
Starting logging the timing of applying additions and removals to the coin store.
Made max message size configurable in config.yaml, as a possible workaround for very large farms where reporting plot information exceeds the maximum message size.
Added a config option for peer_connect_timeout.
Added support for unhardened key derivations.
Various CoinStore benchmark and performance improvements.
Beta builds are built on every merge to main, and are now available from https://chia.net/download/.
Thanks @Radexito for adding support for Raspberry Pi 4 64Bit to the GUI installation script.
Added macOS keyring.yaml support, migrating keys from macOS Keychain to keyring.yaml to support an upcoming release in which we'll add an optional passphrase to wallets.
We have made many full node changes to support our upcoming Chia Asset Token (CAT) standard and our upcoming standalone light wallet, which will use Chia's new electrum-style protocol to enable faster wallet syncing.
We have many new translations added in this release. Thanks to the following community members for their contributions: Albanian @ATSHOOTER; Arabic @younes.huawei.test; Belarusian @LUXDAD; Catalan @Poliwhirl; Chinese Traditional @MongWu-NeiTherHwoGer-Long, @danielrangel6; Chinese, Simplified @SupperDog; Croatian @vjukopila5 @marko.anti12; Czech @HansCZ; Danish @loppefaaret; Dutch @netlob;English @sharjeelaziz @darkflare; English, Australia @nzjake; English, New Zealand @nzjake @sharjeelaziz; Finnish @f00b4r; French @burnt; Hungarian @SirGeoff; Hebrew @Arielzikri; Indonesian @lespau;Lithuanian @Mariusxz; Polish @bartlomiej.tokarzewski; Portuguese @darkflare; Portuguese, Brazilian @fsavaget; Sinhala @HelaBasa;Slovak @atomsymbol; Spanish @needNRG; Spanish, Argentina @juands1644 @gdestribats; Spanish, Mexico @danielrangel6; Swedish @MrDyngrak; Thai @3bb.pintakam.7m1 @taweesak0803650558 @taweesak.25may1993 @3bb.pintakam.7m1; Turkish @baturman @ExtremeSTRAUSSER.

Changed

Bluebox proofs are now randomized instead of looking at the oldest part of the blockchain first to find uncompacted proofs.
Bumped sortedcontainers to version 2.4.0.
Dropped some redundant code in plotting/manager.py
Updated some hooks: Update flake8 to 3.9.2, pre-commit-hooks to 4.0.1, black to 21.8b0
Bump clvm_rs to 0.1.14.
Added tests for invalid list terminators in conditions.
Updated blspy to 1.0.6.
Made a change to allow the host to be configurable for the timelord launcher.
Thanks @dkackman for adding the ability to collect the IDs of plots as they are queued and return them with the response.
Made the SpendBundle.debug use the default genesis challenge by default.
Changes in full node to execute sqlite pragmas only once, at the level where the database is opened, and changed pragma synchronous=FULL to OFF to improve disk I/O performance. Also removed redundant database pragmas in wallet.
Made a change to remove CoinStore's dependency on FullBlock to just pass in the parts of the block necessary to add the block.
Improved log formatting.
A change to logging to only log warnings when more than 10 seconds has passed, to reduce the number of warning logs.
Improved and fixed some outdated messages in CLI. Thanks @jack60612 for the assist!
We previously added a Rust condition checker, to replace our existing Python-based condition checker. In this release, we're removing the old Python code.
Several clvm_rs updates to support our upcoming Chia Asset Token (CAT) standard.

Fixed

Thanks @mgraczyk for the fix to keyring_path.
Fixed an issue blocking the Ubuntu installer that required manual installation of Python 3.9 as a workaround.
Fixed an issue where the config.yaml and keyring.yaml are only partially written out to, if another process is attempting to read the config while it's being written.
Fixed rmtree call in create_pool_plot.
Thanks @Knight1 for fixing an issue in which fix-ssl-permissions shows the current 'mode' not the 'updated mode'.
Fixed Mypy issues on Python 3.9.7 that generated many errors when running mypy.
Thanks @olivernyc for fixing an edge case with negative inputs to 'truncate_to_significant_bits'.

1.2.7 Chia blockchain 2021-09-16

Fixed

Thanks to @jack60612 for fixing a bug that displayed 25 words instead of 24 words in some instances in the GUI.

1.2.6 Chia blockchain 2021-09-09

Today we’re releasing version 1.2.6 to address a resource bug with nodes, and we want to stress the importance of updating to it at the earliest convenience. The fix prevents a node from consuming excessive memory when many Bluebox Timelords are active on the chain.

Changed

Updated to BLS 1.0.6.
Updates to the Rust conditions parser.
Adjusted plot refresh parameter to improve plot loading times.

Fixed

Fixed memory utilization issue related to how the node handles compact VDFs generated from blueboxes. We recommend everyone update to this version to avoid memory issues that can impact farming and harvesting.
Fixed issues with reloading plot files detected as bad (this can happen during plot copying).

1.2.5 Chia blockchain 2021-08-27

Fixed

Fixed errors in the Linux GUI install script, which impacted only Linux users.

1.2.4 Chia blockchain 2021-08-26

Added

Enable the rust condition checker unconditionally in testnet.
Added support for multiple wallets.
Added a change to config.yaml to tolerate fields that replace network constants in config.yaml that don't exist, but print warning.
Improvements to sync full nodes faster by improving the concurrency for downloading and validating blocks.
Added new call for logging peer_host: get_peer_logging that will use the peer_host value, typically an IP address, when the peername cannot be retrieved.
Added documentation for treehash params.
Added a py.typed file that allows other projects that pip install chia-blockchain to type check using our functions with mypy.
Added an RPC for coin records by multiple coin names.
Enabled querying AAAA records for DNS Introducer.
We now set the version for the GUI when doing a manual install using the install-gui.sh script. Uses a python helper to get the version of the chia install and then converts it into proper npm format and puts that into package.json.
Added some new class methods to the Program objects to improve ease of use.
Added an option to sign bytes as well as UTF-8 strings, which is particularly helpful if you're writing Chialisp puzzles that require signatures and you want to test them without necessarily writing a whole python script for signing the relevant data.
Added a first version of .pre-commit-config.yaml and applied the changes required by the following initial hooks in separate commits. To use this you need to install pre-commit, see https://pre-commit.com/#installation/.
We have added many new translations in this release based on community submissions. Thanks to @RuiZhe for Chinese, Traditional; @HansCZ for Czech; @LUXDAD for English, Australia; @f00b4r for Finnish; @jimkoen, @ruvado for German; @Arielzikri for Hebrew; @A-Caccese for Italian; @Hodokami for Japanese; @LUXDAD for Latvian; @vaexperience for Lithuanian; @LUXDAD for Russian; @juands1644 for Spanish, Argentina; @MrDyngrak, @ordtrogen for Swedish; @richeyphu for Thai; @Ansugo, @baturman for Turkish.

Changed

Thanks @altendky for Correct * to ** kwargs unpacking in time_out_assert().
Thanks @altendky for changing the default to paginate to chia wallet get_transactions to address cases such as piping and output redirection to a file where the command previously just hung while waiting for the user to press c for the next page.
Removed commented-out debug breakpoints.
Enabled Rust condition checker to add the ability to parse the output conditions from a generator program in Rust. It also validates some of the conditions in Rust.
Switched IP address lookup to first use Chia's service ip.chia.net.
Made changes so that when creating SSL certificate and private key files, we ensure that files are written with the proper file permissions.
Define a new encrypted keyring format to be used to store keys, and which is optionally encrypted to a user-supplied passphrase. GUI for the passphrase will come in an upcoming release.
Removed initial transaction freeze put in place at mainnet launch as it is no longer necessary.
Separate locking and non-locking cases for get_confirmed_balance_for_wallet, which will allow calling a few wallet_state_manager methods while already under the wallet_state_manager lock, for example during DID wallet creation.
Thanks to @Playwo for removing the index on coin_record spent column to speed up querying.
Made a change to the conditions parser to either ignore or fail when it encounters unknown conditions. It also removes the UNKNOWN enum value from ConditionOpcodes.
Renamed folder tests/core/types to tests/core/custom_types to address conflicts in debugger in PyCharm.
Disabled DID wallet tests while DID wallet is under construction.
Added pairing cache for faster aggregate signature verification.
Added block height assertions after block farming.
Added assertions for tx confirmation.

Fixed

Fix single coin generator.
Fixed an issue with duplicate plotnft names.
Fixed an issue during node shutdown in which some AttributeErrors could be thrown if the shutdown happens before the node fully started up.
Fixed mempool TX cache cost, where the cost of the mempool TX cache (for spend bundles that can't be included in a block yet) would not be reset when the cache was emptied.
Fixed a failure to create a keychain_proxy for local keychains.
Thanks to @mgraczyk for fixing type annotation in sync_store.
Thanks to @darkverbito for fixing an issue on initial creation of a coloured coin where code always falls into default else clause due to lack of type conversion.
Fixed NPM publish in clvm_rs.
Thanks to @skweee for his investigation work on fixing mempool TX cache cost, where the cost of the mempool TX cache (for spend bundles that can't be included in a block yet) would not be reset when the cache was emptied.

1.2.3 Chia blockchain 2021-07-26

Added

Added ability to change payout instructions in the GUI.
Added an option to revert to sequential read. There are some systems (primarily macos+exfat) where the parallel read features results in very long lookup times. This addition makes the parallel feature the default, but adds the ability to disable it and revert back to sequential reads.
Added backwards compatibility for Coin Solutions in push_tx since renaming it to CoinSpend.
Added an option to set the default constants on the simulator.
Added a warning to user to not send money to the pool contract address.
Added capability to enable use of a backup key in future, to claim funds that were sent to p2_singleton_puzzle_hash, which today are just ignored.
Thanks @aarcro for adding timing metrics to plot check.
Thanks @chadwick2143 for adding the ability to set the port to use for the harvester.
Added more friendly error reporting for peername errors.
We have added many new translations in this release. Thanks to @L3Sota, @hodokami and @L3Sota for Japanese; @danielrangel6, @memph1x and @dvd101x for Spanish (Mexico); @fsavaget, @semnosao and @ygalvao for Portuguese (Brazilian); @juands1644 for Spanish (Argentina); @darkflare for Portuguese; @wong8888, @RuiZhe, @LM_MA, @ezio20121225, @GRIP123, @11221206 and @nicko1122 for Chinese Traditional; @atomsymbol for Slovak; @SirGeoff and @rolandfarkasCOM for Hungarian; @ordtrogen for Swedish; @HansCZ and @kafkic for Czech; @SupperDog for Chinese Simplified; @baturman and @Ansugo for Turkish; @thebacktrack for Russian; @itservicelukaswinter for German; @saeed508, @Amirr_ezA and @themehran for Persian; @hgthtung for Vietnamese; @f00b4r for Finnish; @IMIMIM for Latvian; @Rothnita and @vanntha85 for Khmer; @Rothnita and @Gammaubl for Thai; @marcin1990 for Polish; @mydienst for Bosnian; @dvd101x and @darkflare for Spanish; @ATSHOOTER for Albanian; @Munyuk81 for Indonesian; @loppefaaret for Danish; @sharjeelaziz and @nzjake for English; @nzjake for English (New Zealand). We apologize if we missed anyone and welcome corrections.

Changed

Updated blspy to 1.0.5.
Updated chiapos to 1.0.4.
Included all Chialisp files in source distribution.
Removed left-over debug logging from test_wallet_pool_store.
Made changes to allow us to use the name coin_spend everywhere in our code, without changing it in the API requests, both outgoing and incoming. Enables us to decide at a later date when to cut over completely to the coin_spend name.
Thanks @mishan for your change to 'chia plotnft show' to display Percent Successful Points.
Thanks @Playwo for your change to make pool payout instructions case insensitive.
GUI sees update when plots or harvesters change.
Increased the cache interval to help large farmers.
Removed proof limit for mainnet, but not testnet. This helps with pools that have very low difficulties. Thanks to @AlexSSD7 for pointing out the issue.
We now also allow hex strings prefixed with 0x which is required because we currently prefix the strings in JSON conversion.
Thanks to @opayen for your help in updating our MacOS icon.

Fixed

Thanks to @dfaranha for helping fix a parsing error in Relic inputs for BLS signatures.
Fixed error type in wallet_blockchain.py.
Thanks to @seraphik for a fix on our Linux installer that required root privileges.
Thanks @felixbrucker for helping fix invalid content-type header issues in pool API requests.
The wallet ignores coins sent by accident to the pool contract address and allows self pooling rewards to be claimed in this case.
Thanks @mgraczyk for fixing the use of print_exc in farmer.

1.2.2 Chia blockchain 2021-07-13

Fixed

Converted test_rom.py to use pytest and fixed test_singleton.
Thanks to @yshklarov for help fixing #7273, which bundled CA store to support pools for some farming systems, including M1 Apple computers. This enables those machines to properly connect to pools, and fixes the issue.

1.2.1 Chia blockchain 2021-07-12

Added

Thanks @feldsam for adding support for Fedora in install-gui script

Fixed

Fix harvester cache updates. Prior to this commit the farmer called the request_plots every second for each harvester as long as they failed to respond properly. Since the rate limit was 10/minute this lead to hitting the rate limit if the harvester didn't responds for 10 tries in a row for whatever reason. This commit changes the behavior to always keep track of request attempts even if they end up in a timeout to really only re-try every 60s no matter what.
Fix M1 installed torrent and installer version number
Thanks to @x-Rune for helping find and test a lot of 1.2.0 bugs with the harvester.
Fixed issue for Debian users where the wallet crashes on start for them since last release

1.2.0 Chia blockchain 2021-07-07

Added

Portable pooled plots are now available using our new plot NFT. These allow you to plot new plots to an NFT that can either self farm or join and leave pools. During development there were changes to the plot NFT so portable pool plots (those made with -c option to chia plots create) using code from before June 25th are invalid on mainnet. OG plots made before this release can continue to be farmed side by side with the new portable pool plots but can not join pools using the official pooling protocol. You can learn more as a farmer by checking out the pool user guide. Pool operators and those wanting to understand how the official pooling protocol operates should check out our pooling implementation reference repository. If you plan to use plot NFT, all your farmers and harvesters must be on 1.2.0 to function properly for portable pool plots.
The exact commit after which Plot NFTs should be valid is the 89f7a4b3d6 commit (in which pools.testnet9 branch was merged to main) or 5d62b3d148 within the pools.testnet9 branch.
chia farm summary and the GUI now use a new RPC endpoint to properly show plots for local and remote harvesters. This should address issues #6563, #5881, #3875, #1461.
chia configure now supports command line updates to peer count and target peer count.
Thank you @gldecurtins for adding logging support for remote syslog.
Thanks to @maran and @Animazing for adding farmer and pool public key display to the RPC.
We have added translations for Hungarian, Belarusian, Catalan, and Albanian. For Hungarian thanks to @SirGeoff, @azazio @onokaxxx, @rolandfarkasCOM, @HUNDavid , @horvathpalzsolt, @stishun74, @tusdavgaming, @idotitusz, @rasocsabi, @mail.kope, @gsprblnt, @mbudahazi, @csiberius, @tomatos83, @zok42, @ocel0t, @rwtoptomi, @djxpitke, @ftamas85, @zotya0330, @fnni, @kapabeates, @zamery, @viktor.gonczi, @pal.suta, @miv, and @Joeman_. For Belarusian thanks to @shurix83, @haxycgm, and @metalomaniax. For Catalan thank you to @Poliwhirl, @Pep-33, @marqmarti, @meuca, @Guiwdin, @carlescampi, @jairobtx, @Neoares, @darknsis, @augustfarrerasgimeno, and @fornons. Finally for Albanian thanks to @ATSHOOTER and @lakedeejay. We apologize if we missed anyone and welcome corrections.
Our release process is now fully automated from tagging a release to publishing installers to all of the appropriate locations and now makes the release artifacts available via torrents as well.
All Chia repositories now automatically build M1 wheels and create a new MacOS M1 native installer.
New CLI command chia plotnft to manage pools.
We have added a new RPC get_harvesters to the farmer. This returns information about remote harvesters and plots.
We have added a new RPC check_delete_key to the wallet, to check keys prior to deleting them.
We have added a new RPC delete_unconfirmed_transactions to the wallet which deletes these transactions for a given wallet ID.
We have added a new RPC get_puzzle_and_solution to the full node, which takes in a coin ID.
We have added a new RPC get_recent_signage_point_or_eos to the full node, to support pooling.
We have added a new RPC send_transaction_multi to the wallet, which sends a payment with multiple payees.

Changed

We have made a host of changes to the GUI to support pooling and to improve the wallet experience.
We updated chiapos to version 1.0.3. This adds parallel reads to GetFullProof. Thanks to @marcoabreu ! We now print target/final directory early in the logs refs and log process ID. Thanks to @grayfallstown ! We are now using Gulrak 1.5.6. @683280 optimized code in phase1.hpp. @jespino and @mrhacky started migrating to flags instead of booleans parameters for show_progress and nobitfield. If you are providing third-party tools you may need to make adjustments if relying on the chiapos log.
Updated chiavdf to version 1.0.2 to fix certain tests.
Windows builds now rely upon Python 3.9 which obviates the fix in 1.1.7.
We are now using miniupnpc version 2.2.2 so that we can support Python 3.9 on Windows.
We updated to clvm 0.9.6 and clvm_rs 0.1.8. CLVMObject now lazily converts python types to CLVM types as elements are inspected in clvm. cvlm_rs now returns python objects rather than a serialized object.
We now have rudimentary checks to makes sure that fees are less than the amount being spent.
The harvester API no longer relies upon time:time with thanks to @x1957.
We have increased the strictness of validating Chialisp in the mempool and clvm.
Thanks to @ruslanskorb for improvements to the human-readable forms in the CLI.
Thanks to @etr2460 for improvements to the plotting progress bar in the GUI and enhancements to human-readable sizes.
@dkackman changed the way that configuration was found on startup.
We now delay peer start for wallet until after backup init and make sure only one copy is started.
Wallets now trust the local node more for enhanced wallet sync speed.
We now store tasks used to initiate peer connections to ensure they are kept alive and to be able to wait for them if we hit the upper limit on number of pending outgoing connections.
We improved weight proof validation.
@cvet changed the wallet to take override instead of confirm.

Fixed

The delete plots button in the Windows GUI has been fixed and re-enabled.
Sometimes upon startup, the GUI takes a while to load the plots to display. We've made a temporary improvement that adds a "Refresh Plots" button whenever the GUI has not yet found plots.
Correctly display private key in chia keys show.
Thanks to @gldecurtins for removing a default printout of the private key mnemonic in chia keys show.
Shutting down the full node is cleaner and manages uPnP better.
DNS introducer could fail.
Fixed a potential timelord bug that could lead to a chain stall.
Add an explicit error message when mnemonic words are not in the dictionary; should help users self-service issues like #3425 faster. Thank you to @elliotback for this PR.
Thank you to @Nikolaj-K for various typo corrections around the Mozilla CA, code simplifications and improvements in converting to human-readable size estimations, and clean up in the RPCs and logging.
Thank you to @ChiaMineJP for various improvements.
@asdf2014 removed some useless code in the wallet node API.
Thanks to @willi123yao for a fix to under development pool wallets.
chia farm summary better handles wallet errors.
@Hoinor fixed formatting issues around the Chinese translation in the GUI.
Sometimes the GUI would stop refreshing certain fields.
We have better error handling for misbehaving peers from naive forks/clones.
We have fixed an error where the wallet could get corrupted, which previously required restarting the application.
We have fixed an error where transactions were not being resubmitted from the wallet.

Known Issues

If you resync your wallet, transactions made with your plot NFTs will show incorrectly in the GUI. The internal accounting, and total balance displayed is correct.

1.1.7 Chia Blockchain 2021-06-05

Fixed

Batch process weight proof epochs in groups of 900 to fit below May 2020 sqlite limit (999 for Python 3.7 on Windows). Fixes sqlite3.OperationalError: too many SQL variables error and resulting issues with syncing wallets on Windows.

1.1.6 Chia Blockchain 2021-05-20

Added

This is the initial release of our DNS introducer. We built a far too simple basic introducer that we hoped to replace as quickly as possible with an introducer that uses DNS in the style of Bitcoin. This release will now use both and as we gain testing with the DNS version, we will slowly be phasing the classic introducers out. This should significantly help in finding nodes to connect and sync to.
You can now whitelist networks and hosts so that a node can always connect with chosen peers.
We added a simple profiler to track performance times in the application (see /chia/util/profiler.py for instructions).
We added a transaction filter to get_header_blocks_in_range.
There is now an unspent coin count and pending coin removal count to wallet_rpc_api.
Added configuration options for moving an install to testnet and back (use chia configure -t true|false).
Added Arabic language support. Thank you to the following community members for their translation contributions: @MohamedSiddig, @bilalghalib, @HoussenAlSamer, @esmailelbob, @MCoreiX, @bestq8, @bt.layth, @sam_774, @yahyakhalid, @itsmekarim44, @anasjawabreh1996, @algeria98, @abduallh, @rabee.khalil, @ajoolee.

Added Spanish (Mexico) language support. Thank you to the following community members for their translation contributions: @javieriv, @dvd101x, @cdgraff, @danielrangel6.
Thanks to @proea for adding RockyLinux support for install-gui.sh.
And thank you to @etr2460 for various GUI contributions.

Changed

Performance improvement of speeding up outbound connections.
Performance improvements to block_store.
Optimized Streamable parsing by avoiding extra post-init checks, making parsing block records from database up to 40% faster.
Made the serialization of Coin follow the normal protocol of implementing stream().
Minor improvements to add_spendbundle and weight proofs.
We now use version 1.0.2 of chiapos. We now reopen files on read or write failure with thanks to @mreid-moz! We also prevent chiapos prover crashing for more bad plots.
Disabled deletion of running plot for Windows users as the crash/lockup bug has returned.
We more clearly prohibit root from installing/running the GUI.
Thanks to @sargonas for improvements to the template for creating Issues.
Thanks to @aisk for continuing to add more types.
Thanks for @dkackman for improving the remote harvester setup by having init -c only copy the right certs.
And thank you to @vidschofelix, @meawoppl, and @rongou for various other changes and improvements.

Fixed

Fixed a bug where multiple wallets running at the same time would all issue a transaction.
Fixed issues with signage points: duplicate signage point spikes, and bugs in signage point cache.
Fixed a blank screen error during Centos install.
Thanks to @linnik for fixing a TypeError exception in case of unresponsive service.
Thanks to @msg7086 for fixing install.sh for Debian.
And thank you to @alfonsoperez, @asdf2014, @fredericosilva, @lamba09, @Nikolaj-K, @sargonas, @aisk, @Ich5003, and @trumankain for various other fixes and improvements.

1.1.5 Chia Blockchain 2021-05-09

Fixed

We were not checking for negative values in the uint64 constructor. Therefore coins with negative values were added to the mempool. These blocks passed validation, but they did not get added into the blockchain due to negative values not serializing in uint64. Farmers making these blocks would make blocks that did not make it into or advance the chain, so the blockchain slowed down starting at block 255518 around 6:35AM PDT 5/9/2021. The fix adds a check in the mempool and block validation, and does not disconnect peers who send these invalid blocks (any peer 1.1.4 or older), making this update not mandatory but is recommended. Users not updating might see their blocks get rejected from other peers. Upgraded nodes will show an error when they encounter an old node trying to send an invalid block. This "Consensus error 124..." can be safely ignored.

1.1.4 Chia Blockchain 2021-05-04

Changed

Secret wallet key is hidden by default in chia keys show. Use chia keys show --show-mnemonic-seed for private keys.
Performance improvement while parsing variable length field in transaction blocks.

Fixed

Spends are now sorted in the mempool by fee/cost.
Resolved pending transaction issue during reorgs.
Fixed bug in message send retry logic.
Two issues with processing Weight Proofs during syncing while farming.
Fixed a bug in the outgoing rate control logic that could prevent messages being sent.

1.1.3 Chia Blockchain 2021-05-01

Added

Significant speed improvements have been added to the Node during P2P operations. This is mostly a performance improvement to make sure there is plenty of overhead in Node for transaction processing. Smaller machines like the Pi 4 are strongly advised to update to this release before Monday 5/3/21 at 10AM PDT when transactions start.
Significant syncing speed improvements have been added. However, there is a lot of low hanging fruit to continue to increase overall chain sync speed in subsequent releases.

Changed

We now require node 12.x to build the GUI. Installers have been building using node 12.x for quite some time.
Node will now farm while syncing.
We changed chialisp singletons to take a puzzlehash as its origin. We also updated the DID wallet to use this.
Transactions are now cached for 10 minutes in mempool to retry if there is a failure of a spending attempt.
Thank you to @Chida82 who made the log rotation count fully configurable. Apologies to him for not initially being included here.
Thank you to @fiveangle for making install.sh more resilient across python installations.
Standard transactions now all have announcements.
VDF verification during sync and normal operations are now cached to enhance node performance.
Target peer count has been increased from 60 to 80 to increase the number of peer Nodes available to connect to. Outbound connections were lowered from 10 to 8.
The streamables class has had significant performance improvements.
If a proof of space lookup takes longer than 5 seconds we will now log an error at WARNING level.
Allow configuration of the plot loading interval (default is 2 minutes) in config.yaml.
CLI wallet UI was improved and shows syncing status of wallet.
@martomi added logging of added coins back.
Thank you to @aisk for additional type checking.
@aisk added error checking in bech32m
Chialisp programs now remained serialized in Node for better performance.
Mempool is now set to be 50 times the single block size.
Mitigate 1-3 mojo dust attacks.
CLI now switches to EiB for netspace display as appropriate.

Fixed

We fixed excess memory use when displaying plot logs in GUI. This was causing the GUI application to fail in many "fun" ways after plotting a lot of plots in parallel.
Fixed plot update issues in the GUI.
Long syncing will now correctly show "Syncing" around the application.
Nonce collisions in request IDs is fixed.
Some duplicate plots were not being caught and logged by harvester on loading.
We have removed many places where Node was making duplicate requests of other nodes.
Daemon now waits for services to end to attempt to avoid zombie processes.
Node is less likely to lose sync due to state inconsistency.
A large thank you to @sargonas for diagnosing why so many technical support questions were flooding GitHub issues, PRing a fix, and mass migrating issues to Discussions.
Thanks to @jeolcho for fixing a bug in full_node_rpc_api.py.
Thanks @antoniobg for a typo fix in keychain.py.
Thanks to @altendky for catching a Copyright date error.

1.1.2 Chia Blockchain 2021-04-24

Changed

Weight proof time outs have been increased from 3 minutes to 6 minutes.

Fixed

When attempting to sync, connections could accidentally disconnect for rate limiting reasons. This was causing many to not be able to sync.
Some temp files were not being closed during GUI plotting.

1.1.1 Chia Blockchain 2021-04-21

Added

This is a bug fix release for 1.1.0. It is not required to upgrade from 1.1.0 if you are not experiencing the specific issue that it addresses. You are required to upgrade from any 1.0.x version before Monday evening PDT to continue farming.

Changed

Logging now includes year, month, and date. Thanks and apologies for not tipping the hat sooner to @alfonsoperez for the PR.

Fixed

Changes were made in 1.1.0 to make sure that even out of order signage points were found and responded to by as many farmers as possible. That change lead to a situation where the harvester could thrash on the same cached signage point.

1.1.0 Chia Blockchain 2021-04-21

Added

This fork release includes full transaction support for the Chia Blockchain. Transactions are still disabled until 5/3/2021 at 10:00AM PDT. It is hard to overstate how much work and clean up went into this release.
This is the 1.0 release of Chialisp. Much has been massaged and finalized. We will be putting a focus on updating and expanding the documentation on chialisp.com shortly.
Farmers now compress blocks using code snippets from previous blocks. This saves storage space and allows larger smart coins to have a library of sorts on chain.
We now support offline signing of coins.
You can now ask for an offset wallet receive address in the cli. Thanks @jespino.
When adding plots we attempt to detect a duplicate and not load it.

Changed

We have changed how transactions will unlock from a blockheight to a timestamp. As noted above that timestamp is 5/3/2021 at 10AM PDT.
We have temporarily disabled the "Delete Plots" button in the Windows GUI as we are still working on debugging upstream issues that are causing it.
There are various optimizations in node and wallet to increase sync speed and lower work to stay in sync. We expect to add additional significant performance improvements in the next release also.
Transactions now add the agg_sig_me of the genesis block for chain compatibility reasons.
Wallet is far less chatty to unload the classic introducers. DNS introducers will be coming shortly to replace the classic introducers that are still deployed.
Netspace is now calculated across the previous 4068 blocks (generally the past 24 hours) in the GUI and cli.

Fixed

Performance of streamable has been increased, which should help the full node use less CPU - especially when syncing.
Timelords are now successfully infusing almost 100% of blocks.
Harvester should be a bit more tolerant of some bad plots.

1.0.5 Chia Blockchain 2021-04-14

Added

This is a maintenance release for 1.0.4 to fix a few mostly cosmetic issues. Please refer to the 1.0.4 notes for the substantive plotting changes - for example - in that release.

Changed

The GUI now calls it an Estimated Time to Win and has enhanced explanations in the tool tip that the estimated time is often not be the actual time. We have some additional improvements we plan to make here in future releases.
Development installers now handle semver development versions correctly.

Fixed

Temp space sizes needed for k = 33 and higher were accidentally under-reported. The values we have placed into the GUI may be conservative in being too large and appreciate feedback from the community on the new optimal temp space needed and RAM choices.
The GUI plotting progress bar was reaching 100% too early. Thanks to @davidbb for the PR.
Help -> About was blank.
Our estimate for k=32 was about 0.4GiB too low in some cases.
Building the GUI in especially ARM64 Linux was painful enough to be considered broken.

1.0.4 Chia Blockchain 2021-04-12

Added

Starting approximately April 21, 2021, the GUI will notify you that this version will stop working at block height 193,536 and will persistently warn you from that block on that you can not use this version (or any earlier version) to farm. This is to support the upgrade to the transaction fork.
We now have translations for Brazilian Portuguese, Australian English, and Pirate. Thanks to @fsavaget, @darkflare, @maahhh, @harold_257, @kontin, and @GunnlaugurCalvi. Yarr - don't be losing your 24 word treasure map...

Changed

The plotter in bitfield mode is much improved in plotting speed (~15% faster than in 1.0.3), now requires 28% less temporary space (238.3 GiB/256 GB), and now uses its maximum memory in phase 1 and only needs 3389MiB for optimal sorting of a k32. Total writes should also be down by about 20%. On almost all machines we expect bitfield to be as fast or faster. For CPUs that predate the Nehalem architecture, bitfield plotting will not work and you will need to use no bitfield. Those CPUs were generally designed before 2010.
The src directory in chia-blockchain has been changed to chia to avoid namespace collisions.
GUI install builds have been simplified to rely on one .spec file in chia/
The weight proof timeout can now be configured in config.yaml.
Peer discovery is now retried more often after you receive initial peers.

Fixed

We have made significant improvements and bug fixes to stop blockchain and wallet database corruption issues.
We now pass the environment into the Daemon and this should solve some Windows and MacOS startup bugs.
The ARM64 .deb installer will now work well on Raspberry Pi OS 64 bit and Ubuntu 18.04 LTS or newer.
We have made improvements in weight proof generation and saving.
Wallet start up would have a race condition that output a harmless error on startup.
Thanks for a typo fix from @alfonsoperez.

1.0.3 Chia Blockchain 2021-03-30

Added

This is a minor bug fix release for version 1.0.2
You should review the release notes for v1.0.2 but we especially want to point out that wallet sync is much faster than in 1.0.1 and earlier versions.

Fixed

An incorrect merge brought in unreleased features and broke chia keys.
Omitted from the 1.0.2 changelog, we fixed one crash in harvester with the release of chiapos 1.0.0 as well.

1.0.2 Chia Blockchain 2021-03-30

Added

We have released version 1.0.0 of chiapos. This includes a 20% speed increase for bitfield plotting compared to the previous version on the same machine. In many cases this will mean that bitfield plotting is as fast or faster than non bitfield plotting.
@xorinox improved our support for RedHat related distributions in install.sh.
@ayaseen improved our support for RedHat related distributions in install-timelord.sh.
We have added Dutch and Polish to supported translations. Thanks @psydafke, @WesleyVH, @pieterhauwaerts, @bartlomiej.tokarzewski, @abstruso, @feel.the.code, and @Axadiw for contributions to translations on Crowdin.
The GUI now supports "Exclude final directory" when plotting. This is found in the Advanced Options for step 2 on the plot creation page.

Changed

Wallet now uses a trusted node and, when syncing from that node, Wallet does not do as many validations.
@jespino changed chia keys show to require the --show-mnemonic-seed before it displays your 24 work private key mnemonic.
We decreased the size of the block cache in node to perform better with longer chains.
You can now add a private key mnemonic from a file with chia keys show.
@Flofie caught an error in CONTRIBUTING.md.
We no longer rely on aiter so it has been removed.
Keyring deprecated the use of OS_X in favor of MacOS.
"Broken pipe" error was decreased to a warning.
Many non critical log messages were decreased from warning to info log level.
Harvester should now log the plot file name if it finds a bad plot at error log level.

Fixed

Peer ips were being written to the database on a per ip basis. This caused a lot of wasted disk activity and was costing full node performance.
We fixed an issue where the last block wasn't fetched by the GUI.
There was an edge case with full node store that can stall syncing.
There was a potential node locking issue that could have prevented a Timelord from getting a new peak and cause a chain stall.
We did not correctly support some Crowdin locales. Pirate English was starting to overwrite US English for example.

1.0.1 Chia Blockchain 2021-03-23

Added

There is now a simple progress bar on the GUI Plot page and when you view the log from the three dots on the right.
Users must now explicitly set the --show-mnemonic-seed flag to see their private keys when running chia keys show.
We are now building Linux GUI installers. These should be considered beta quality for now.
Translations now available for German, Traditional Chinese, and Danish. Thanks to @Dravenex, @MaestroOnICe, @loudsyncro, @loppefaaret, @thirteenthd, @wong8888, @N418, and @swjz for all the translation help. You to can translate at our Crowdin project.

Changed

The mainnet genesis is now in the initial config.yaml and the green flag components have been removed.
Our release process and branching strategy has changed. CONTRIBUTING.md will be updated in the main branch soon with details.
This mainnet release does not migrate previous testnet configuration files.

Fixed

Weight proofs, especially wallet weight proofs were failing when some Blueboxed proofs of time were encountered.
Users can now pip install e.g. chia-blockchain==1.0.1 on most platforms.
Sometimes the GUI had an error regarding MainWindow.

1.0.0 First Release of Chia Blockchain 2021-03-17

Added

This is the first production release of the Chia Blockchain. This can be installed and will wait for the green flag that will be dropped at approximately 7AM PDST (14:00 UTC) on Friday March 19, 2021. All farming rewards from that point forward will be considered valid and valuable XCH. There is a six week lock on all transactions. During those six weeks farmers will be earning their farming rewards but those rewards can not be spent.
Initial difficulty will be set for 100PB. This may mean the initial epoch may be slow. Mainnet difficulty resets are targeted for 24 hours so this difficulty will adjust to the actual space brought online in 24 to 48 hours after launch.
Transactions are not enabled in the 1.0.0 version and will be soft forked in during the six week period via a 1.1.0 release.
There will also be a 1.0.1 release after the green flag process is complete to simplify install for new users by removing the green flag alert. In the interim there will be new testnet releases using the 1.1bx version scheme.
Starting with release 1.0.0 you usually no longer need to upgrade and 1.0.1 will be fully optional. However you will have to upgrade to 1.1 after it is out and before the six week period ends. We plan to give plenty of time between those two events up to and including pushing back the transaction start date by a short period of time.
Thank you to @L3Sota for adding a Japanese translation via our Crowdin project.
The generation of CoinIDs is now unique on mainnet to avoid testnet transaction replays.
Validation of transactions will now fail after the expiration of the six week period.

Changed

Weight proof request timeout was increased to 180 seconds.
Mainnet uses port 8444 and other constants and service names were changed for mainnet.
GUI locales are now extracted and compiled in npm run build.
Daemon now logs to STDERR also.

Fixed

GUI plotting on some Macs was not working due to locale issues with Click.
Thank you @L3Sota for bringing this log back into 2021.
The errant warning on Electron startup has been removed. Thanks @dkackman.

1.0rc9 aka Release Candidate 9 - 2021-03-16

Changed

This is a hard fork/breaking change from RC6/7/8. The current plan is to drop the flag at noon pacific time, today 3/16.
Using the real prefarm keys for this test

Fixed

Found and fixed another green flag related issue
Fixed an issue with weight proofs where all sub-epochs were sampled, and the size of the weight proof kept growing
Fixed an issue with install-gui.sh, where npm audit fix was failing. (Thanks @Depado!)
Migration with CHIA_ROOT set does not crash chia init

1.0rc8 aka Release Candidate 8 - 2021-03-15

Added

This is a hard fork/breaking change from RC6/7. TXCH Coins will not be moved forward but your plots and keys and parts of your configuration do. When you install this version before 10AM PDST on 3/16/2021 it will load up, start finding peers, and otherwise wait for the flag drop at that time to start farming. This is likely to be the last dress rehearsal for mainnet launch. Our 3/15/2021 blog post has more details on the current mainnet launch plan.
The GUI now has a tooltip that directs users to the explanation of the plot filter.
The GUI now has a tooltip to explain the "Disable bitfield plotting" option. Thanks @shaneo257 for the idea.
The GUI now has a tooltip to explain Hierarchical Deterministic keys next to Receive Address on the Wallet page.

Changed

We now use Python 3.9 to build MacOS installers.
Harvester now catches another error class and continues to harvest. Thanks to @xorinox for this PR.
We now use a smaller weight proof sample size to ease the load on smaller machines when syncing.
Starting the GUI from Linux will now also error out if npm run build is run outside the venv. Huge thanks to @dkackman for that PR.
chia farm summary will now display TXCH or XCH as appropriate.
We added more time to our API timeouts and improved logging around times outs.

Fixed

We no longer use the transaction cache to look up transactions for new transactions as that was causing a wallet sync bug.
Sometimes the GUI would not pick up the fingerprint for the plotting key.
chia farm summary displayed some incorrect amounts.
Weight proofs were timing out.
Changes to farming rewards target addresses from the GUI were not being saved for restart correctly.
Signage points, recent deficit blocks, and slots for overflow challenge blocks had minor issues.

1.0rc7 aka Release Candidate 7 - 2021-03-13

Changed

Our green flag test blockchain launch worked but it uncovered a flaw in our installer versions. This release is a bug fix release to address that flaw. You should read the RC6 changes below if this is your first time installing since RC5.
Thanks to @dkackman for implementing an early exit of the GUI if you run npm run build without being in the venv.
chia netspace now defaults to 1000 blocks to mirror the GUI.
The installer build process was spruced up some.

Fixed

Setting difficulty way too low on the testnet_6 launch revealed a Timelord edge case. The full node was hardcoding the default difficulty if block height is < EPOCH_BLOCKS. However there were many overlapping blocks, so none of the blocks reached the height, and therefore the timelord infused the wrong difficulty.
Fixed a race condition in the Timelord, where it took time to update the state, so it ignored the new_peak_timelord form the full_node, which should have reset the timelord to a good state.
Wallet notoriously showed "not synced" when it was in sync.
Installers were not correctly placing root TLS certificates into the bundle.
Weight proofs had a logic typo.
There was a typo in chia netspace. Thanks @altendky.
There was a typo in chia plots. Thanks @adamfiddler.

Known Issues

Some users can't plot in the GUI in MacOS Big Sur - especially on M1. See issue 1189

1.0rc6 aka Release Candidate 6 - 2021-03-11

Added

This is a hard fork/breaking change from RC5. TXCH Coins will not be moved forward but your plots and keys and parts of your configuration do. We will be testing the final mainnet release strategy with the launch of RC6. For the test, those who are comfortable running the dev branch will update and start up their farms. All harvesters and plots will load and until the green flag drops, peers will be gossiped so your farm can establish good network connectivity. When the flag drops, each node will pull down the signed genesis challenge and start farming. Block 1 will be broadcast to anyone who hasn't seen the flag drop yet. The only difference for mainnet is that there will be 1.0 installers and a main branch release more than 24 hours before the real green flag.
There is now basic plot queueing functionality in the GUI. By default, plotting works as it has in the past. However you can now name a queue in Step 2 Advanced Options. Chose something like first. Everything you add to the first queue will start up like it has in the past but now you can go through the steps again and create a queue named second and it will immediately start plotting as if it is unaware of and parallel with first. A great use case is that you would set first to plot 5 plots sequentially and then you'd set second to plot 5 sequentially and that would give you two parallel queues of 5 plot's each. We will be returning to plotting speed and UI soon. Thanks @jespino for this clever work around for now.
There is now an option on the Farm page to manage your farming rewards receive addresses. This makes it easy to send your farming rewards to an offline wallet. This also checks your existing rewards addresses and warns if you do not have the matching private key. That is expected if you are using an offline wallet of course.
Functionally has been added to the farmer rpc including checking and changing your farming rewards target addresses.
Added the ability to translate material-ui components like Row 1 of 10. Thanks @jespino.
Arch linux support has been added to sh install.sh. Thanks @jespino.
Update FullBlock to Allow Generator References - a list of block heights of generators to be made available to the block program of the current block at generator runtime. This sets the stage for smart coins calling existing "libraries" already on the chain to lower fees and increase the scale of complex smart coins.

Changed

Remove chia plots "-s" "--stripe_size" and the strip size setting in the Advanced section of the GUI. We now always use the best default of 64K for the GUI and cli.
chia keys add takes secret words a prompt on the command line or stdin instead of command line arguments for security.
Version 1.0.1 of chiavdf was added. This brought MPIR on Windows to the most recent release. Additionally we removed inefficient ConvertIntegerToBytes() and ConvertBytesToInt() functions, use GMP library's mpz_export/mpz_import for big integers and simple helper functions for built-in integer types. The latter are taken from chiavdf. We now require compressed forms to be encoded canonically when deserializing. This should prevent potential grinding attacks where some non-canonical encodings of a compressed form could be used to change its hash and thus the next challenges derived from it. Canonically encoded compressed forms must be reduced and must produce the same string when deserialized and serialized again.
Version 1.0 of our BLS signature library is included. We brought Relic, gmp and MPIR up to their most recent releases. We again thank the Dash team for their fixes and improvements.
We now hand build Apple Silicon native binary wheels for all chia-blockchain dependencies and host them at https://pypi.chia.net/simple. We are likely to hand build a MacOS ARM64 dmg available and certainly will for 1.0. You can install natively on M1 now with the git clone developer method today. Just make sure Python 3.9 is installed. python3 --version works.
The GUI now shows you which network you are connected to on the Full Node page. It will also wait patiently for the green flag to drop on a network launch.
In the GUI you can only plot k=32 or larger with the single exception of k=25 for testing. You will have to confirm choosing k=25 however. Thanks to @jespino for help on this and limiting the cli as well.
The restore smart wallets from backup prompt has been improved to better get the intent across and that it can be skipped.
At the top of the plotting wizard we have added text pointing out that you can plot without being in sync or on the internet.
Wallet no longer automatically creates a new hierarchical deterministic wallet receive address on each start. You can and still should choose a new one with the NEW ADDRESS button for each new transaction for privacy.
The network maximum k size is now set to k=50. We think that may be more storage than atoms in the solar system so it should be ok. But we will probably be hated for it in 200 years...
The formula for computing iterations is simplified, so that only one division is necessary, and inverting the (1-x) into just x.
There are new timestamp consensus rules. A block N must have a greater timestamp than block N-1. Also, a block's timestamp cannot be more than 5 minutes in the future. Note that we have decided that work factor difficulty resets are now going to be 24 hours on mainnet but are still shorter on testnet.
A List[Tuple[uint16, str]] is added to the peer network handshake. These are the capabilities that the node supports, to add new features to the protocol in an easy - soft fork - manner. The message_id is now before the data in each message.
Peer gossip limits were set.
Generators have been re-worked in CLVM. We added a chialisp deserialization puzzle and improved the low-level generator. We reduce the accepted atom size to 1MB during ChiaLisp native deserialization.
When processing mempool transactions, Coin IDs are now calculated from parent coin ID and amount
We implemented rate limiting for full node. This can and will lead to short term bans of certain peers that didn't behave in expected ways. This is ok and normal, but strong defense against many DDOS attacks.
requirements-dev.txt has been removed in favor of the CI actions and test scripts.
We have moved to a new and much higher scalability download.chia.net to support the mainnet launch flag and additional download demand.
To always get the latest testnet and then mainnet installers you can now use a latest URL: Windows and MacOS x86_64.
Chia wheels not on Pypi and some dependecies not found there also are now on pypi.chia.net.
Additional typing has been added to the Python code with thanks to @jespino.
Cryptography and Keyring have been bumped to their current releases.
PRs and commits to the chia-blockchain-gui repository will automatically have their locales updated.

Fixed

The Farm page will now no longer get stuck at 50 TXCH farmed.
chia farm has had multiple bugs and spelling issues addressed. Thanks to @alfonsoperez, @soulmerge and @olivernyc for your contributions.
chia wallet had various bugs.
Various weight proof improvements.
Some users on Big Sur could not plot from the GUI as the log window would be stuck on "Loading."
We believe we have fixed the chain stall/confused Timelord bug from ~ 13:00 UTC 3/10/21. We've added additional recovery logic as well.
Logs from receiving a duplicate compacted Proof of Time are much more human friendly.
We believe that the install/migrate process was bringing forward bad farming rewards receive addresses. We have attempted to stop that by only migrating RC3 and newer configurations. You can make sure you are not effected by using the Manage Farming Rewards tool mentioned above or putting a known good wallet receive address in both xch_target_address sections of config.yaml.
Wallet cached transactions incorrectly in some cases.

1.0rc5 aka Release Candidate 5 - 2021-03-04

Added

The RC5 release is a new breaking change/hard fork blockchain. Plots and keys from previous chains will work fine on RC5 but balances of TXCH will not come forward.
We now support a "green flag" chain launch process. A new version of the software will poll download.chia.net/notify/ for a signed json file that will be the genesis block of the chain for that version. This will allow unattended start at mainnet.
Bluebox Timelords are back. These are Timelords most anyone can run. They search through the historical chain and find large proofs of times and compact them down to their smallest representation. This significantly speeds up syncing for newly started nodes. Currently this is only supported on Linux and MacOS x86_64 but we will expand that. Any desktop or server of any age will be fast enough to be a useful Bluebox Timelord.
Thanks to @jespino there is now chia farm summary. You can now get almost exactly the same farming information on the CLI as the GUI.
We have added Romanian to the GUI translations. Thank you to @bicilis on Crowdin. We also added a couple of additional target languages. Klingon anyone?
chia wallet now takes get_address to get a new wallet receive address from the CLI.
chia plots check will list out all the failed plot filenames at the end of the report. Thanks for the PR go to @eFishCent.
Chialisp and the clvm have had the standard puzzle updated and we replaced ((c P A)) with (a P A).

Changed

Testnets and mainnet now set their minimum k size and enforce it. RC5 testnet will reject plots of size less than k=32.
Sub slots now require 16 blocks instead of 12.
Thanks to @xdustinface of Dash, the BlS Signature library has been updated to 0.9 with clean ups and some speed ups. This changed how the G2 infinity element was handled and we now manage it inside of chia-blockchain, etc., instead of in blspy.
We have updated the display of peer nodes and moved adding a peer to it's own pop up in the GUI.
Block searching in the GUI has been improved.
@jespino added i18n support and refactored how locales are loaded in the GUI. Additionally he moved more strings into the translation infrastructure for translators.
In chiavdf we changed n-Wesolowski proofs to include B instead of y in segments. Proof segments now have the form (iters, B, proof) instead of (iters, y, proof). This reduces proof segment size from 208 to 141 bytes.
The new chiavdf proof format is not compatible with the old one, however zero-Wesolowski proofs are not affected as they have zero proof segments and consist only of (y, proof).
We made two HashPrime optimizations in chiavdf. This forces numbers being tested for primality to be odd and avoids an unnecessary update of the sprout vector by stopping after the first non-zero value. This is a breaking change as it changes the prime numbers generated from a given seed. We believe this is the final breaking change for chiavdf.
chiabip158 was set to a gold 1.0 version.
Comments to Chialisp and clvm source have been updated for all of the Chialisp changes over the proceeding three weeks.
And thanks yet again to @jespino for a host of PRs to add more detailed typing to various components in chia-blockchain.
aiohttp was updated to 3.7.4 to address a low severity security issue.
calccrypto/uint128_t was updated in the Windows chiapos implementation. Chiapos required some changes its build process to support MacOS ARM64.

Fixed

Harvester would crash if it encountered more than 16,000 plot files or 256 directories.
Nodes that were interrupted by a network crash or standby on a laptop were not syncing upon reconnection in RC4.
Sync issues could stop syncing from restarting and could lead to a peer host that you could not remove.
Adding Click changed the behavior of chia keys add -m. The help now makes it clear that the 24 word mnemonic needs to be surrounded by a pair of quotes.
Python root CA certificates have issues so we have added the Mozilla certificate store via curl.se and use that to connect to backup.chia.net via https, for example.
The difficulty adjustment calculation was simplified.
All of the chia sub repositories that were attempting to build MacOS Universal wheels were only generating x86_64 wheels internally. We have moved back to only generating x86_64 MacOS wheels on CI.
However, we have updated and test compiled all Chia dependencies on Apple Silicon and will be making available a test .dmg for MacOS ARM64 shortly.
Various weight proof edge cases have been fixed.
Various typos and style clean ups were made to the Click CLI implementation. chia -upnp f was added to disable uPnP.
chia plots check shouldn't crash when encountering plots that cause RuntimeError. PR again thanks to @eFishCent.
Coloured coin announcements had a bug that would allow counterfeiting.

1.0rc4 aka Release Candidate 4 - 2021-02-25

Fixed

This is a bug fix release for RC3. There was an unexpected interaction between the GUI and the Click cli tool regarding Windows that made GUI plotting not start on all GUIs.

1.0rc3 aka Release Candidate 3 - 2021-02-25

Added

RC3 is a new chain to support the last major chialisp changes. TXCH from the RC1/2 chain do not come forward to this chain but plots and keys continue to work as usual.
We have lowered the transaction lock to the first 5000 blocks to facilitate testing. We also started this chain at a lower difficulty.
A new RPC api: /push_tx. Using this RPC, you can spend custom chialisp programs. You need to make a SpendBundle, which includes the puzzle reveal (chialisp), a solution (chialisp) and a signature.
You can now use the RPC apis to query the mempool.
There are now Swedish, Spanish, and Slovak translations. Huge thanks to @ordtrogen (Swedish), @jespino and @dvd101x (Spanish), and our own @seeden (Slovak). Also thanks were due to @f00b4r (Finnish), @A-Caccese (Italian), and @Bibop182 and @LeonidShamis (Russian). Quite a few more are almost complete and ready for inclusion. You can help translate and review translations at our crowdin project.
You can obtain a new wallet receive address on the command line with chia wallet new_address. Thanks to @jespino for this and a lot more in the next section below.
You will now see Your Harvester Network in the GUI even if you have no plots.

Changed

All chialisp opcodes have been renumbered. This should be the last major breaking change for chialisp and the clvm. There are a couple minor enhancements still needed for mainnet launch, but they may or may not require minor breaking changes. We will be restarting testnet chains on a mostly weekly basis either way.
Node batch syncing performance was increased, and it now avoids re-validating blocks that node had already validated.
The entire CLI has been ported to Click. Huge thanks to @jespino for the big assist and @unparalleled-js for the recommendation and the initial start. This will make building out the CLI much easier. There are some subtle changes and some shortcuts are not there anymore. chia -h and chia SUBCOMMAND -h can be your guide.
We have upgraded Electron to 11.3 to support Apple Silicon. There are still one or two issues in our build chain for Apple Silicon but we should have an M1 native build shortly.
The websocket address is no longer displayed in the GUI unless it is running as a remote GUI. Thanks @dkackman !
chia plots check now will continue checking after it finds an error in a plot to the total number of checks you specified.
If you run install-gui.sh or install-timelord.sh without being in the venv, the script will warn you that you need to . ./activate and exit with error.
If you attempt to install on a 32 bit Pi/ARM OS, the installer exits with a helpful error message. You can still fail when running under a 64 bit kernel but using a 32 bit Python 3.
The application is now more aware of whether it is running a testnet or mainnet. This impacts wallet's display behavior and certain blockchain validation rules.
Interface improvements for chia netspace.
Now that aiosqlite included our upstream improvements we install version 0.17.0.
chia init only migrates release candidate directories. The versioned sub directories under ~/chia will be going away before mainnet.

Fixed

The GUI was often getting stuck on connecting to wallet. We beleive we have resolved this.
We identified and fixed an issue where harvester would crash, especially when loading plots or checking a large amount of plots.
The software now reports not synced in the GUI if not synced or being behind by 7 minutes or more.
Difficulty was set too high for the RC1/2 chain. This lead to odd rewards behaviour as well as difficulty artificially could not fall as low as it should.
Don't load plots that don't need to be loaded.
We made various fixes and changes to weight proofs.
Some configuration values were improperly ignored in migrations.
Some debug logging was accidentally left in.
chia configure -log-level was broken.
We believe we finally have the Windows Installer obtaining the correct version information at build time.
The application was sometimes not cancel pending items when closing certain websockets.
Fixed filter hash and generator validation.
Recursive replace was being called from the test suite.

1.0rc2 aka Release Candidate 2 - 2021-02-18

Fixed

This is an errata release for Release Candidate 1. There were a couple of things that did not smoothly migrate from the Beta versions. Please make sure you also consult the release notes for RC-1 was well.
Incorrect older spend to addresses were being migrated from Beta 27. This would send farming rewards to un-spendable coins.
Netspace was not calculating properly in RC-1.
The Windows installer was building with the wrong version number.
@eFishCent didn't get correct credit in the RC 1 release notes. They have been updated below to be correct.

1.0rc1 aka Release Candidate 1 - 2021-02-18

Added

This is the first release in our release candidate series. There are still a few things that will change at the edges but the blockchain, clvm, and chialisp are in release form. We have one major change to chialisp/clvm that we have chosen to schedule for the next release as in this release we're breaking the way q/quote works. We also have one more revision to the VDF that will decrease the sizes of the proofs of time. We expect a few more releases in the release candidate series.
Installers will now be of the pattern ChiaSetup-0.2.1.exe. 0.2 is release candidate and the final .1 is the first release candidate.
Use 'chia wallet get_transactions' in the command line to see your transactions.
'chia wallet show' now shows your wallet's height.
Last Attempted Proof is now above Latest Block Challenge on the Farm page of the GUI.
The GUI now detects duplicate plots and also only counts unique plots and unique plot size.
We have integrated with crowdin to make it easier to translate the GUI. Check out Chia Blockchain GUI there.
We have added Italian, Russian, and Finnish. More to come soon.
There is now remote UI support. Documents will temporarily live in the repository but have moved to the wiki. Thanks to @dkackman for this excellent addition!
Added the ability to specify an address for the pool when making plots (-c flag), as opposed to a public key. The block validation was changed to allow blocks like these to be made. This will enable changing pools in the future, by specifying a smart transaction for your pool rewards.
Added chia plots check --challenge-start [start] that begins at a different [start] for -n [challenges]. Useful when you want to do more detailed checks on plots without restarting from lower challenge values you already have done. Huge thanks to @eFishCent for this and all of the debugging work behind the scenes confirming that plot failures were machine errors and not bugs!

Changed

Sub blocks renamed to blocks, and blocks renamed to transaction blocks, everywhere. This effects the RPC, now all fields that referred to sub blocks are changed to blocks.
Base difficulty and weight have increased, so difficulty of "5" in the rc1 testnet will be equivalent to "21990232555520" in the previous testnet.
'chia wallet send' now takes in TXCH or XCH as units instead of mojos.
Transactions have been further sped up.
The blockchain database has more careful validation.
The GUI is now using bech32m.

Fixed

We updated chiapos to hopefully address some harvester crashes when moving plot files.
Many of the cards on the Farming page have had bugs addressed including last block farmed, block rewards, and user fees.
Improved validation of overflow blocks.

[1.0beta27] aka Beta 1.27 - 2021-02-11

Added

The Beta 27 chain is a hard fork. All TXCH from previous releases has been reset on this chain. Your keys and plots of k=32 or larger continue to work just fine on this new chain.
We now use the rust version of clvm, clvm_rs, in preference to validate transactions. We have additionally published binary wheels or clvm_rs for all four platforms and all three supported python versions. The rust version is approximately 50 times faster than the python version used to validate on chain transactions in previous versions.
We have moved to compressed quadratic forms for VDFs. Using compressed representation of quadratic forms reduces their serialized size from 130 to 100 bytes (for forms with 1024-bit discriminant). This shrinks the size of VDF outputs and VDF proofs, and it's a breaking change as the compressed representation is not compatible with the older uncompressed (a, b) representation. Compressed forms are also used in calls to chiavdf and in timelord's communication with VDF clients. The form compression algorithm is based on "Trustless Groups of Unknown Order with Hyperelliptic Curves" by Samuel Dobson, Steven D. Galbraith and Benjamin Smith.
Last Attempted Proof on the Farm tab of the GUI now shows hours:minutes:seconds instead of just hours:minutes. This makes it much easier to see that your farmer is responding to recent challenges at a glance.
You can now send and receive transactions with the command line. Try chia wallet -h to learn more. Also, chia wallet now requires a third argument of show, therefor you will use chia wallet show to see your wallet balance.
We have added the Crowdin translation platform to chia blockchain gui. We are still getting it fully set up, but helping to translate the GUI is going to be much easier.
Full Node > Connections in the GUI now shows the peak sub block height your connected peers believe they are at. A node syncing from you will not be at the true peak sub block height until it gets into sync.
chia init -c [directory] will create new TLS certificates signed by your CA located in [directory]. Use this feature to configure a new remote harvester. Type chia init -h to get instructions. Huge thanks to a very efficient @eFishCent for this quick and thorough pull request.
We build both MacOS x86_64 and MacOS universal wheels for chiapos, chiavdf, blpsy, and chiabip158 in Python 3.9. The universal build allows M1 Macs to run these dependencies in ARM64 native mode.
On first run in the GUI (or when there are no plot directories) there is now an "Add Plot Directories" on the Farm tab also.

Changed

We are moving away from the terms sub blocks and blocks in our new consensus. What used to be called sub blocks will now just be blocks. Some blocks are now also transaction blocks. This is simpler both in the code and to reason about. Not all the code or UI may have caught up yet.
This release has the final mainnet rewards schedule. During the first three years, each block winner will win 2 TXCH/XCH per block for a total of 9216 TXCH per day from 4608 challenges per day.
Smart transactions now use an announcement instead of 'coin consumed' or lock methods.
The GUI is now in a separate submodule repository from chia-blockchain, chia-blockchain-gui. The installers and install scripts have been updated and it continues to follow the same install steps. Note that the GUI directory will now be chia-blockchain-gui. The workflow for this may be "touch and go" for people who use the git install methods over the short term.
Very large coin counts are now supported.
Various RPC endpoints have been renamed to follow our switch to "just blocks" from sub blocks.
We've made changes to the protocol handshake and the blockchain genesis process to support mainnet launch and running/farming more than one chain at a time. That also means we can't as easily determine when an old version of the peer tries to connect so we will put warnings in the logs for now.
We no longer replace addresses in the config. IMPORTANT - This means if you change the target address in config.yml, you have to make sure you control the correct keys.
We now only migrate Beta 19 and newer installations.
We have removed cbor2 as a dependency.
We updated various dependencies including cryptography, packaging, portalocker, and pyyaml - most of which are only development dependencies.

Fixed

The function that estimated total farming space was counting space at twice the actual rate. Netspace will display half of the previous space estimate which is now a correct estimate of the actual space currently being farmed.
We fixed many sync and stay in sync issue for both node and wallet including that both would send peaks to other peers multiple times and would validate the same transaction multiple times.
The GUI was incorrectly reporting the time frame that the netspace estimate it displays utilizes. It is technically 312.5 minutes, on average, over the trailing 1000 sub blocks.
Coloured coins were not working in the new consensus.
Some Haswell processors do not have certain AVX extensions and therefor would not run.
The cli wallet, chia wallet, was incorrectly displaying TXCH balances as if they were Coloured Coins.
We addressed CVE-2020-28477 in the GUI.
We made changes to CI to hopefully not repeat our skipped releases from the previous release cycle.

[1.0beta26] aka Beta 1.26 - 2021-02-05

Added

We now use our own faster primality test based on Baillie-PSW. The new primality test is based on the 2020 paper "Strengthening the Baillie-PSW primality test" by Robert Baillie, Andrew Fiori, Samuel S. Wagstaff Jr. The new test works approximately 20% faster than GMP library's mpz_probab_prime_p() function when generating random 1024-bit primes. This lowers the load on Timelords and speeds up VDF verifications in full node.
The GUI now checks for an an already running GUI and stops the second launch. Thank you for that PR to @dkackman !
Transactions are now validated in a separate process in full node.
chia plots check -l will list all duplicate plot IDs found on the machine. Thanks very much for this PR @eFishCent.

Changed

Significant improvements have been made to how the full node handles the mempool. This generally cuts CPU usage of node by 2x or more. Part of this increase is that we have temporarily limited the size of transactions. If you want to test sending a transaction you should keep the value of your transaction below 20 TXCH as new consensus will cause you to use a lot of inputs. This will be returned to the expected level as soon as the integration of clvm rust is complete.
We have changed the way TLS between nodes and between chia services work. Each node now has two certificate authorities. One is a public, shared CA that signs the TLS certificates that every node uses to connect to other nodes on 8444 or 58444. You now also have a self generated private CA that must sign e.g. farmer and harvester's certificates. To run a remote harvester you need a new harvester key that is then signed by your private CA. We know this is not easy for remote harvester in this release but will address it quickly.
We have changed the way we compile the proof of space plotter and added one additional optimization. On many modern processors this will mean that using the plotter with the -e flag will be 2-3% faster than the Beta 17 plotter on the same CPU. We have found this to be very sensitive to different CPUs but are now confident that, at worst, the Beta 24 plotter with -e will be the same speed as Beta 17 if not slightly faster on the same hardware. Huge thanks to @xorinox for meticulously tracking down and testing this.
If a peer is not responsive during sync, node will disconnect it.
Peers that have not sent data in the last hour are now disconnected.
We have made the "Help Translate" button in the GUI open in your default web browser and added instructions for adding new translations and more phrases in existing translations at that URL. Try the "Help Translate" option on the language selection pull down to the left of the dark/light mode selection at the top right of the GUI.
Sync store now tracks all connected peers and removes them as they get removed.
The Rate Limited Wallet has been ported to new consensus and updated Chialisp methods.
We are down to only one sub dependency that does not ship binary wheels for all four platforms. The only platform still impacted is ARM64 (generally Raspberry Pi) but that only means that you still need the minor build tools as outlined on the wiki.
We upgraded to Electron 9.4.2 for the GUI.
We have upgraded to py-setproctitle 1.2.2. We now have binary wheels for setproctitle on all four platforms and make it a requirement in setup.py. It is run-time optional if you wish to disable it.

Fixed

On the Farm page of the GUI Latest Block Challenge is now populated. This shows you the actual challenge that came from the Timelord. Index is the signage point index in the current slot. There are 64 signage points every 10 minutes on average where 32 sub blocks can be won.
Last Attempted Proof is now fixed. This will show you the last time one of your plots passed the plot filter.
Plot filename is now back in the Plots table of the GUI.
There was a bug in adding a sub block to weight proofs and an issue in the weight proof index.
Over time the node would think that there were no peers attached with peak sub block heights higher than 0.
There was a potential bug in Python 3.9.0 that required us to update blspy, chiapos, chiavdf, and chiabip158.
An off by one issue could cause syncing to ask for 1 sub block when it should ask for e.g. 32.
Short sync and backtrack sync both had various issues.
There was an edge case in bip158 handling.

Known issues

There is a remaining sync disconnect issue where your synced node will stop hearing responses from the network even though it still gets a few peaks and then stalls. Restarting node should let you quickly short sync back to the blockchain tip.

Added

The GUI now displays sub blocks as well as transaction blocks on the Full Node page.
chia plots check enforces a minimum of -n 5 to decrease false negatives. Thanks to @eFishCent for these ongoing pull requests!
Testnets and mainnets will now have an initial period of sub blocks where transactions are blocked.
Transaction volume testing added to tests and various tests have been sped up.
We have added connection limits for max_inbound_wallet, max_inbound_farmer, and max_inbound_timelord.

Changed

On starting full node, the weight proof cache does not attempt to load all sub blocks. Startup times are noticeably improved though there remains a hesitation when validating the mempool. Our clvm Rust implementation, which will likely ship in the next release, will drop example processing times from 180 to 3 seconds.
Changes to weight proofs and sub block storage and cacheing required a new database schema. This will require a re-sync or obtaining a synced blockchain_v23.db.
clvm bytecode is now generated and confirmed that the checked-in clvm and ChiaLisp code matches the CI compiled code.
We have removed the '-r' flag from chia as it was being overridden in most cases by the -r for restart flag to chia start. Use chia --root-path instead.
chia -h now recommends chia netspace -d 192 which is approximately one hours worth of sub blocks. Use -d 1000 to get the same estimate of netspace as the RPC and GUI.
chia show -c now displays in MiB and the GUI has been changed to MiB to match.
chia configure now accepts the shorter -upnp and -log-level arguments also.
chia plots check now defaults to -n 30 instead of -n 1 - HT @eFishCent.
chia plots create now enforces a minimum of k=22. As a reminder, anything less than k=32 is just for testing and be careful extrapolating performance of a k less than 30 to a k=32 or larger.
We have updated development dependencies for setuptools, yarl, idna, multidict, and chardet.
Updated some copyright dates to 2021.

Fixed

We upgraded our fork of aiosqlite to version 16.0 which has significant performance improvements. Our fixes to aiosqlite are waiting to be upstreamed.
The Plots tab in the GUI will no longer show red/error when the node is still syncing.
Inbound and outbound peer connection limits were not being honored.
Weight proofs were not correctly extending.
In some cases when closing a p2p connection to another node, there was an infinite "Closing" loop.
chia show -c was showing upload MiB in the download column and vice versa. @pyl and @psydafke deserves credit for insisting it was broken and @kd637xx for the PR assist.
chia show handles sub block 0 better.

[1.0beta22] aka Beta 1.22 - 2021-01-19

Added

Node now attempts to pre-validate and cache transactions.
The harvester will try to not load a plot file that is too small for its k size. This should help keep from partial plots being found when they are copied into a harvester directory. Harvester will check again on the next challenge and find a completed copy of a plot file then.
chia plots create -x skips adding [final dir] to harvester for farming

Changed

We now use bech32m and have added the bech32m tests from Pieter Wuille (@sipa) outlined here with thanks.
In the GUI, choosing to parallel plot with a delay now is a delay between the start of the parallel plots started in one session.
Removed loading plot file names when starting chia plots create; decreases plotter time when there are a lot of plots on the machine. Huge thanks to @eFishCent for this PR!

Fixed

Various fixes to improve node's ability to sync. There are still plenty of additional performance improvements coming for node so expect it to get easier to run on less powerful devices.
Wallet now handles large amounts of coins much better and generally syncs better.
Thanks to @nup002 for the PR to use scientific notation in the logs for address_manager.select_peer timings.
chia show -h now correctly states that you use the first 8 characters of the node id to remove a node on the cli.
Thank you to @wallentx for adding better help for chia configure --enable-upnp.
Pull requests from forks won't have failures on CI.

[1.0beta21] aka Beta 1.21 - 2021-01-16

Added

The cli now warns if you attempt to create a plot smaller than k=32.
chia configure now lets you enable or disable uPnP.
If a peer gives a bad weight proof it will now be disconnected.

Changed

Harvester now only checks every 2 minutes for new files and otherwise caches the plot listing in memory and logs how long it took to load all plot files at INFO level.
Harvester multithreading is now configureable in config.yaml.
Websocket heartbeat timeout was increased from 30 seconds to 300 seconds.
Bumped Colorlog to 4.7.2, and pyinstaller to 4.2.

Fixed

Weight proofs were failing to verify contributing to a chain stall. This release gets things moving again but nodes are using too much CPU and can pause/lag at times. This may resolve as people upgrade to Beta 21.
A toxic combination of transaction limits set too high and a non performant clvm kept the chain stalled. A faster rust implementation of clvm is already nearing completion.
chia netspace -s would not correctly look up the start block height by block hash. Additionally netspace now flips to PiB above 1024 TiB. To compare netspace to chia show of the GUI use chia netspace -d 1000 as chia netspace defaults to -d 192 which is one hour.

[1.0beta20] aka Beta 1.20 - 2021-01-14

Added

Plotting now checks to see if there are MacOS created ._ plot files and ignores them.
Mnemonics now autocomplete in the GUI.

Changed

Node sync is now multithreaded and much quicker.
Peer gossip is faster and smarter. It also will no longer accidentally gossip a private IP address to another peer.
When syncing in the GUI, estimated time to win just shows syncing until synced.
If harvester hits an exception it will be caught, logged and skipped. This normally happens if it attempts to harvest a plot file you are still copying in.
The Rate Limited wallet has been updated to work in new consensus.

Fixed

There was a bug in block reorg code that would keep a peer with a lower weight chain from validating and syncing to a higher weight chain when the node thought it had a double spend in the other chain. This caused a persistent chain split.
The Farm page in the GUI should not report just error when initially starting to sync.

[1.0beta19] aka Beta 1.19 - 2021-01-12

Added

Welcome to the new consensus. This release is an all but a full re-write of the blockchain in under 30 days. There is now only one tip of the blockchain but we went from two chains to three. Block times are now a little under a minute but there are a couple of sub blocks between each transaction block. A block is also itself a special kind of sub block and each sub block rewards the farmer who won it 1 TXCH. Sub blocks come, on average, about every 17 to 18 seconds.
Starting with this Beta, there are 4608 opportunities per day for a farmer to win 1 TXCH compared to Beta 18 where there were 288 opportunities per day for a farmer to win 16 TXCH.
There is a lot more information and explanation of the new consensus algorithm in the New Consensus Working Document linked from chia.net. Among the improvements this gives the Chia blockchain are a much higher security level against all attacks, more frequent transaction blocks that have less time variation between them and are then buried under confirmations (sub blocks also count towards re-org security) much more quickly.
New consensus means this is a very hard fork. All of your TXCH from Beta 17/18 will be gone. Your plots and keys will work just fine however. You will have to sync to the new chain.
You now have to sync 16 times more "blocks" for every 5 minutes of historical time so syncing is slower than it was on the old chain. We're aware of this and will be speeding it up and addressing blockchain database growth in the nest couple of releases.
Prior to this Beta 19, we had block times that targeted 5 minutes and rewarded 16 TXCH to one farmer. Moving forward we have epoch times that target 10 minutes and reward 32 TXCH to 32 farmers about every 17-18 seconds over that period. This has subtle naming and UI impacts in various places.
Total transaction throughput is still targeted at 2.1x Bitcoin's throughput per hour but you will get more confirmations on a transaction much faster. This release has the errata that it doesn't limit transaction block size correctly.
For testing purposes this chain is quickly halving block rewards. By the time you're reading this and using the chain, farmers and pools will be receiving less than 1 TXCH for each block won as if it were 15-20 years from now. Block rewards are given in two components, 7/8's to the pool key and 1/8 to the farmer. The farmer also receives any transaction fees from the block.
You can now plot in parallel using the GUI. A known limitation is that you can't yet specify that you want 4 sets of two parallel plots. Each parallel plot added starts immediately parallel. We will continue to improve this.
The GUI now warns if you attempt to create a plot smaller than k=32.
Added Chinese language localization (zh-cn). A big thank you to @goomario for their pull request!
You can now specify which private key to use for chia plots create. After obtaining the fingerprint from chia keys show, try chia plots create -a FINGERPRINT. Thanks to @eFishCent for this pull request!
We use a faster hash to prime function for chiavdf from the current release of gmp-6.2.1 which we have upgraded chiavdf and blspy to support.
There is a new cli command - chia configure. This allows you to update certain configuration details like log level in config.yaml from the command line. This is particularly useful in containerization and linux automation. Try chia configure -h. Note that if chia services are running and you issue this command you will have to restart them for changes to take effect but you can use this command in the venv when no services are running or call it directly by path in the venv without activating the venv. Expect the options for this command to expand.
We now fully support Python 3.9.

Changed

The Plot tab on the GUI is now the Plots tab. It starts out with a much more friendly new user wizard and otherwise keeps all of your farming plots listed here. Use the "+ ADD A PLOT" button in the top right to plot your second or later plot.
The new plots page offers advanced plotting options in the various "Show Advanced Options" fold outs.
The plotter supports the new bitfield back propagation method and the old method from Beta 17. To choose the old method add a -e to the command line or choose "Disable bitfield plotting" in "Show Advanced Options" of the Plots tab. Bitfield back propagation writes about 13% less total writes and can be faster on some slower hard drive temp spaces. For now, SSD temp space will likely plot faster with bitfield back propagation disabled. We will be returning to speed enhancements to the plotter as we approach and pass our mainnet launch.
The Farm tab in the GUI is significantly enhanced. Here you have a dashboard overview of your farm and your activity in response to challenges blockchain challnegs, how long it will take you - on average - to win a block, and how much TXCH you've won so far. Harvester and Full Node connections have moved to Advanced Options.
Harvester and farmer will start when the GUI starts instead of waiting for key selection if there are already keys available. This means you will start farming on reboot if you have the Chia application set to launch on start.
Testnet is now running at the primary port of 58444. Update your routers appropriately. This opens 8444 for mainnet.
All networking code has been refactored and mostly moved to websockets.
RPCs and daemon now communicate over TLS with certificates that are generated into ~/.chia/VERSION/config/
We have moved to taproot across all of our transactions and smart transactions.
We have adopted chech32m encoding of keys and addresses in parallel to bitcoin's coming adoption of bech32m.
The rate limited wallet was updated and re-factored.
All appropriate Chialisp smart transactions have been updated to use aggsig_me.
Full node should be more aggressive about finding other peers.
Peer disconnect messages are now set to log level INFO down from WARNING.
chiavdf now allows passing in input to a VDF for new consensus.
sha256tree has been removed from Chialisp.
chia show -s has been refactored to support the new consensus.
chia netspace has been refactored for new consensus.
aiohttp, clvm-tools, colorlog, concurrent-log-handler, keyring, cryptography, and sortedcontainers have been upgraded to their current versions.
Tests now place a cache of blocks and plots in the ~/.chia/ directory to speed up total testing time.
Changes were made to chiapos to correctly support the new bitfiled backpropogation on FreeBSD and OpenBSD. With the exception of needing to work around python cryptography as outlined on the wiki, FreeBSD and OpenBSD should be able to compile and run chia-blockchain.
With the change to new consensus many components of the chain and local database are not yet stored optimally. Startup and sync times may be slower than usual so please be patient. This will improve next release.
Errata: Coinbase amount is missing from the GUI Block view.
Eratta: wallet Backup, and Fly-sync on the wallet are currently not working.

Fixed

There was a regression in Beta 18 where the plotter took 499GiB of temp space for a k32 when it used to only use 332GiB. The plotter should now use just slightly less than it did in Beta 17.
blspy was bumped to 0.3.1 which now correctly supports the aggsig of no signatures and is built with gmp-6.2.1.
Fixed a plotter crash after pulling a disk without ejecting it first.
sh install.sh now works properly on Linux Mint.
chia show -s now is less brain dead when a node is initially starting to sync.

[1.0beta18] aka Beta 1.18 - 2020-12-03

Added

F1 generation in the plotter is now fully parallel for a small speedup.
We have bitfield optimized phase 2 of plotting. There is only about a 1% increase in speed from this change but there is a 12% decrease in writes with a penalty of 3% more reads. More details in PR 120. Note that some sorts in phase 2 and phase 3 will now appear "out of order" and that is now expected behavior.
Partial support for Python 3.9. That includes new versions of Chia dependencies like chiabip158.

Changed

We have moved from using gulrak/filesystem across all platforms to only using it on MacOS. It's required on MacOS as we are still targeting Mojave compatibility. This should resolve Windows path issues.
We upgraded to cbor 5.2.0 but expect to deprecate cbor in a future release.

Fixed

A segfault caused by memory leaks in bls-library has been fixed. This should end the random farmer and harvester crashes over time as outlined in Issue 500.
Plotting could hang up retrying in an "error 0" state due to a bug in table handling in some edge cases.
CPU utilization as reported in the plotter is now accurate for Windows.
FreeBSD and OpenBSD should be able to build and install chia-blockchain and its dependencies again.
Starting with recent setuptools fixes, we can no longer pass an empty string to the linker on Windows when building binary wheels in the sub repos. Thanks @jaraco for tracking this down.

[1.0beta17] aka Beta 1.17 - 2020-10-22

Changed

Bumped aiohttp to 3.6.3

Fixed

In the GUI there was a regression that removed the scroll bar on the Plot page. The scroll bar has returned!
In Dark Mode you couldn't read the white on white plotting log text.
To fix a bug in Beta 15's plotter we introduced a fixed that slowed plotting by as much as 25%.
Certain NTFS root mount points couldn't be used for plotting or farming.
Logging had a regression where log level could no longer be set by service.

[1.0beta16] aka Beta 1.16 - 2020-10-20

Added

The Chia GUI now supports dark and light mode.
The GUI now supports translations and localizations. If you'd like to add your language you can see the examples in the locales directory of the chia-blockchain repository.
chia check plots now takes a -g option that allows you to specify a matching path string to only check a single plot file, a wild card list of plot files, or all plots in a single directory instead of the default behavior of checking every directory listed in your config.yaml. A big thank you to @eFishCent for this pull request!
Better documentation of the various timelord options in the default config.yaml.

Changed

The entire GUI has been refactored for code quality and performance.
Updated to chiapos 0.12.32. This update significantly speeds up the F1/first table plot generation. It also now can log disk usage while plotting and generate graphs. More details in the chiapos release notes.
Node losing or not connecting to another peer node (which is entirely normal behaviour) is now logged at INFO and not WARNING. Your logs will be quieter.
Both the GUI and CLI now default to putting the second temporary directory files into the specified temporary directory.
SSL Certificate handling was refactored along with Consensus constants, service launching, and internal configuration management.
Updated to clvm 0.5.3. This fixed a bug in the point_add operator, that was causing taproot issues. This also removed the SExp.is_legit_list function. There were significant refactoring of various smart transactions for simplicity and efficiency.
WalletTool was generally removed.
Deprecated pep517.build for the new standard python -m build --sdist --outdir dist .

Fixed

A bug in bls-singatures/blspy could cause a stack overflow if too many signatures were verified at once. This caused the block of death at 11997 of the Beta 15 chain. Updated to 0.2.4 to address the issue.
GUI Wallet now correctly updates around reorgs.
chiapos 0.12.32 fixed a an out of bounds read that could crash the plotter. It also contains a fix to better handle the case of drive letters on Windows.
Node would fail to start on Windows Server 2016 with lots of cores. This python issue explains the problem.

Known Issues

On NTFS, plotting and farming can't use a path that includes a non root mountpoint. This is fixed in an upcoming version but did not have enough testing time for this release.

[1.0beta15] aka Beta 1.15 - 2020-10-07

Added

Choosing a larger k size in the GUI also increases the default memory buffer.

Changed

The development tool WalletTool was refactored out.
Update to clvm 0.5.3.
As k=30 and k=31 are now ruled out for mainnet, the GUI defaults to a plot size of k=32.

Fixed

Over time the new peer gossip protocol could slowly disconnect all peers and take your node offline.
Sometimes on restart the peer connections database could cause fullnode to crash.

[1.0beta14] aka Beta 1.14 - 2020-10-01

Added

Node peers are now gossiped between nodes with logic to keep connected nodes on disparate internet networks to partially protect from eclipse attacks. This is the second to last step to remove our temporary introducer and migrate to DNS introducers with peer gossip modeled directly off of Bitcoin. This adds a new database of valid peer nodes that will persist across node restarts. This also makes changes to config.yaml's contents.
For 'git clone' installs there is now a separate install-gui.sh which speeds up running install.sh for those who wish to run headless and makes docker and other automation simpler.
The rate limited wallet library now supports coin aggregation for adding additional funds after the time of creation.
Fees are now used in all applicable rate limited wallet calls
New parameters for plotting: -r (number of threads) -s (stripe size) -u (number of buckets) in cli and GUI
chiavdf now has full IFMA optimizations for processors that support it.

Changed

Multithreading support in chiapos, as well as a new algorithm which is faster and does 70% less IO. This is a significant improvement in speed, much lower total writing, and configurability for different hardware environments.
Default -b changed to 3072 to improve performance
The correct amount of memory is used for plotting
sh install.sh was upgraded so that on Ubuntu it will install any needed OS dependencies.
Wallet and puzzlehash generation have been refactored and simplified.
Wallet has had various sync speed ups added.
The rpc interfaces of all chia services have been refactored, simplified, and had various additional functionality added.
Block timestamps are now stored in the wallet database. Both database versions were incremented and databases from previous versions will not work with Beta 14. However, upon re-sync all test chia since Beta 12 should appear in your wallet.
All vestigial references to plots.yaml have been removed.

Fixed

Temporary space required for each k size was updated with more accurate estimates.
Tables in the README.MD were not rendering correctly on Pypi. Thanks again @altendky.
Chiapos issue where memory was spiking and increasing
Fixed working space estimates so they are exact
Log all errors in chiapos
Fixed a bug that was causing Bluebox vdfs to fail.

[1.0beta13] aka Beta 1.13 - 2020-09-15

Added

Changed

Long_description_content_type is now set to improve chia-blockchian's Pypi entry. Thanks to @altendky for this pull request.
A minor edit was made to clarify that excessive was only related to trolling in the Code of Conduct document.

Fixed

When starting the GUI from an installer or the command line on Linux, if you had not previously generated a key on your machine, the generate new key GUI would not launch and you would be stuck with a spinner.
Farmer display now correctly displays balance.

[1.0beta12] aka Beta 1.12 - 2020-09-14

Added

Rate limited wallets can now have unspent and un-spendable funds clawed back by the Admin wallet.
You can now backup your wallet related metadata in an encrypted and signed file to a free service from Chia Network at backup.chia.net. Simply having a backup of your private key will allow you to fully restore the state of your wallet including coloured coins, rate limited wallets, distributed identity wallets and many more. Your private key is used to automatically restore the last backup you saved to the Chia backup cloud service. This service is open source and ultimately you will be able to configure your backups to go to backup.chia.net, your own installation, or a third party's version of it.
Added a Code of Conduct in CODE_OF_CONDUCT.md.
Added a bug report template in .github/ISSUE_TEMPLATE/bug_report.md.

Changed

This is a new blockchain as we changed how the default puzzle hashes are generated and previous coins would not be easy to spend. Plots made with Beta 8 and newer continue to work, but all previous test chia are left on the old chain and do not migrate over. Configuration data like plot directories automatically migrate in your ~/.chia directory.
Proof of Space now requires significantly less temp space to generate a new plot. A k=32 that used to require 524GiB now requires only 313GiB - generally a 40% decrease across all k sizes.
When plotting, instead of 1 monolithic temp file, there are now 8 files - one for each of the 7 tables and one for sorting plot data. These files are deleted as the -2 or -d final file is written so the final file can fit within the footprint of the temporary files on the same filesystem.
We've made various additional CPU optimizations to the Proof of Space plotter that reduces plotting time by an additional 13%. These changes will also reduce CPU utilization in harvesting.
We have ruled out k=30 for mainnet minimum plot size. k=31 may still make mainnet. k=32 and larger will be viable on mainnet.
We moved to react-styleguidist to develop reusable components in isolation and better document the UI. Thanks to @embiem for this pull request.
Coloured coins have been updated to simplify them, remove 'a', and stop using an 'auditor'.
clvm has been significantly changed to support the new coloured coins implementation.
Bumped cryptography to 3.1. Cryptography is now publishing ARM64 binary wheels to PyPi so Raspberry Pi installs should be even easier.
chia init now automatically discovers previous releases in each new release.

Fixed

chia show -w should now more reliably work. Wallet balances should be more often correct.
View -> Developer -> Developer Tools now correctly opens the developer tools. Thank you to @roxaaams for this pull request!
Fixed 'Receive Address' typo in Wallet. Thanks @meurtn on Keybase.
Fixed a typo in chia show -w with thanks to @pyl on Keybase.
In Windows the start menu item is now Chia Network and the icon in Add/Remove is updated.

[1.0beta11] aka Beta 1.11 - 2020-08-24

Added

The Chia UI now has a proper About menu entry that gives the various component versions and directs people to submit issues on GitHub. Thank you to @freddiecoleman for this pull request!
Ability to run only the farmer, wallet, or timelord services, for more advanced configurations (chia run farmer-only, wallet-only, timelord-only)

Changed

To complement the new About menu, we have revamped all Electron menus and made them OS native. There are now direct links to the Wiki, Keybase, and FAQ in the Help menu.
There are minor improvements to how working space is calculated and displayed by the plotter. The plotter also has additional debugging information in its output.
Successful plots only have an atomic rename.

Fixed

kOffsetSize should have been 10 bits and not 9. This was causing plots, especially larger plots, to fail with "Error 0". This bug was introduced in Beta 8 with the new plot file format.
A bug in aiosqlite was causing tests to hang - especially on the ci. This may also have been causing wallet database corruption.
chia show -w now correctly outputs all wallet types and balances from the local wallet.

[1.0beta10] aka Beta 1.10 - 2020-08-18

Added

Meet our new Rate Limited wallet. You can now fund a wallet from an Admin wallet that will set how many coins can be spent over a given range of blocks for a given User wallet. Once combined with on chain wallet recovery, this makes it much easier to secure your "spending money" wallet so that if it is compromised you have time to get most of the funds back before an attacker can steal them all. This wallet should be considered alpha in this release as additional fixes and functionality will be coming in subsequent releases.
We've added unhardened HD keys to bls-signatures for the smart wallets that need them. We've added significant cross project testing to our BLS implementation.
The python implementation of bls-signatures is now current to the new specification.
chia show -b now returns plot public key and pool public key for each block.
Added cbor2 binary wheels for ARM64 to the Chia simple site. Raspberry Pi should be just a little easier to install.

Changed

Wallet addresses and other key related elements are now expressed in Chech32 which is the Chia implementation of Bech32. All of your old wallet addresses will be replaced with the new Chech32 addresses. The only thing you can't do is send test chia between 1.8/1.9 and 1.10 software. Anyone who upgrades to 1.10 will keep their transactions and balances of test chia from the earlier two releases however.
We added a first few enhancements to plotting speed. For a k=30 on a ramdisk with -b 64 GiB it results in an 11% speedup in overall plotting speed and a 23% improvement in phase 1 speed. Many more significant increases in plotting speed are in the works.
The proof of space document in chiapos has been updated to the new format and edited for clarity. Additionally GitHub actions now has the on demand ability to create the PDF version.
Relic has upstreamed our changes required for the IETF BLS standard. We now build directly from the Relic repository for all but Windows and will be migrating Windows in the next release.
Minor improvements to the Coloured Coin wallet were integrated in advance of an upcoming re-factor.
Smart wallet backup was upgraded to encrypt and sign the contents of the backup.

Fixed

Proof of space plotting now correctly calculates the total working space used in the -t directory.
chia show -w now displays a message when balances cannot be displayed instead of throwing an error. Thanks to @freddiecoleman for this fix!
Fix issue with shutting down full node (full node processes remained open, and caused a spinner when launching Chia)
Various code review alerts for comparing to a wider type in chiapos were fixed. Additionally, unused code was removed from chiapos
Benchmarking has been re-enabled in bls-signatures.
Various node security vulnerabilities were addressed.
Updated keyring, various GitHub actions, colorlog, cbor2, and clvm_tools.

[1.0beta9] aka Beta 1.9 - 2020-07-27

Added

See wallet balances in command line: chia show -w
Retry opening invalid plots every 20 minutes (so you can copy a large plot into a plot directory.)
We've added chia keys sign and chia keys verify to allow farmers to certify their ownership of keys.
Windows BLS Signature library now uses libsodium for additional security.
You can now backup and restore Smart Wallet metadata.
Binary wheels for ARM64/aarch64 also build for python 3.7.
See and remove plot directories from the UI and command line.
You can now specify the memory buffer in UI.
Optimized MPIR for Sandybridge and Ivybridge CPUs under Windows

Changed

chia start wallet-server changed to chia start wallet, for consistency.
All data size units are clarified to displayed in GiB instead of GB (powers of 1024 instead of 1000.)
Better error messages for restoring wallet from mnemonic.

Fixed

Fixed open_connection not being cancelled when node exits.
Increase the robustness of node and wallet shutdown.
Handle disconnection and reconnection of hard drives properly.
Addressed pre-Haswell Windows signatures failing.
MacOS, Linux x64, and Linux aarch64 were not correctly compiling libsodium in the blspy/bls-signatures library.
Removed outdated "200 plots" language from Plot tab.
Fixed spelling error for "folder" on Plot tab.
Various node dependency security vulnerabilities have been fixed.
Request peers was not returning currently connected peers older than 1 day.
Fixed timeout exception inheritance changes under python 3.8 (pull 13528)

Deprecated

Removed legacy scripts such as chia-stop-server, chia-restart-harvester, etc.

[1.0beta8] aka Beta 1.8 - 2020-07-16

Added

We have released a new plot file format. We believe that plots made in this format and with these IETF BLS keys will work without significant changes on mainnet at launch.
We now use chacha8 and blake3 for proof of space instead of the now deprecated AES methods. This should increase plotting speed and support more processors.
Plot refreshing happens during all new challenges and only new/modified files are read.
Updated blspy to use the new IETF standard for BLS signatures.
Added a faster VDF process which generates n-wesolowski proofs quickly after the VDF result is known. This requires a high number of CPUs. To use it, set timelord.fast_algorithm = True in the config file.
Added a new type of timelord helper - blue boxes, which generate compact proofs of time for existing proven blocks. This helps reducing the database size and speeds up syncing a node for new users joining the network. Full nodes send 100 random un-compact blocks per hour to blue boxes, and if timelord.sanitizer_mode = True, the blue box timelord will work on those challenges. Unlike the main timelord, average machines can run blue boxes and contribute to the chain. Expect improvements to the install method for blue boxes in future releases.
From the UI you can add a directory that harvester will always check for existing and new plots. Harvester will only look in the specific directory you specify so you'll have to add any subfolders you want to also contain plots.
The UI now asks for confirmation before closing and shows shutdown progress.
UI now tries to shut down servers gracefully before exiting, and also closes the daemon before starting.
The various sub repositories (chiapos, chiavdf, etc.) now build ARM64 binary wheels for Linux with Python 3.8. This makes installing on Ubuntu 20.04 lts on a Raspberry Pi 3 or 4 easy.
Ci's check to see if they have secret access and attempt to fail cleanly so that ci runs successfully complete from PRs or forked repositories.
Farmer now sends challenges after a handshake with harvester.
The bls-signatures binary wheels include libsodium on all but Windows which we expect to add in future releases.
The chia executable is now available if installing from the Windows or MacOS Graphical installer. Try ./chia -h from ~\AppData\Local\Chia-Blockchain\app-0.1.8\resources\app.asar.unpacked\daemon\ in Windows or /Applications/Chia.app/Contents/Resources/app.asar.unpacked/daemon on MacOS.

Changed

Minor changes have been made across the repositories to better support compiling on OpenBSD. HT @n1000.
Changed XCH units to TXCH units for testnet.
A push to a branch will cancel all ci runs still running for that branch.
Ci's now cache pip and npm caches between runs.
Improve test speed with smaller discriminants, less blocks, less keys, and smaller plots.
RPC servers and clients were refactored.
The keychain no longer supports old keys that don't have mnemonics.
The keychain uses BIP39 for seed derivation, using the "" passphrase, and also stores public keys.
Plots.yaml has been replaced. Plot secret keys are stored in the plots, and a list of directories that harvester can find plots in are in config.yaml. You can move plots around to any directory in config.yaml as long as the farmer has the correct farmer's secret key too.
Auto scanning of plot directories for .plot files.
The block header format was changed (puzzle hashes and pool signature).
Coinbase and fees coin are now in merkle set, and bip158 filter.
New harvester protocol with 2/2 harvester and farmer signatures, and modified farmer and full node protocols.
255/256 filter which allows virtually unlimited plots per harvester or drive.
Improved create_plots and check_plots scripts, which are now "chia plots create" and "chia plots check".
Add plot directories to config.yaml from the cli with "chia plots add".
Use real plot sizes in UI instead of a formula/
HD keys now use EIP 2333 format instead of BIP32, for compatibility with other chains.
Keys are now derived with the EIP 2334 (m/12381/8444/a/b).
Removed the ability to pass in sk_seed to plotting, to increase security.
Linux builds of chiavdf and blspy now use a fresh build of gmp 6.2.1.

Fixed

uPnP now works on Windows.
Log rotation should now properly rotate every 20MB and keep 7 historical logs.
Node had a significant memory leak under load due to an extraneous fork in the network code.
Skylake processors on Windows without AVX would fail to run.
Harvester no longer runs into 512 maximum file handles open issue on Windows.
The version generator for new installers incorrectly handled the "dev" versions after a release tag.
Due to a python bug, ssl connections could randomly fail. Worked around Python issue 29288
Removed websocket max message limit, allowing for more plots
Daemon was crashing when websocket gets improperly closed

Deprecated

All keys generated before Beta 1.8 are of an old format and no longer useful.
All plots generated before Beta 1.8 are no longer compatible with testnet and should be deleted.

Known Issues

For Windows users on pre Haswell CPUs there is a known issue that causes "Given G1 element failed g1_is_valid check" when attempting to generate keys. This is a regression from our previous fix when it was upstreamed into relic. We will make a patch available for these systems shortly.

[1.0beta7] aka Beta 1.7 - 2020-06-08

Added

Added ability to add plot from filesystem (you will need pool_pk and sk from plots.yaml.)
Added ability to import private keys in the UI.
Added ability to see private keys and mnemonic seeds in the keys menu
User can specify log level in the config file (defaults to info.)
The Windows installer is now signed by a Chia Network certificate. It may take some time to develop enough reputation to not warn multiple times during install.

Changed

Plots are now refreshed in the UI after each plot instead of at the end of plotting.
We have made performance improvements to plotting speed on all platforms.
The command line plotter now supports specifying it's memory buffer size.
Test plots for the simulation and testing harness now go into ~/.chia/test-plots/
We have completely refactored all networking code towards making each Chia service use the same default networking infrastructure and move to websockets as the default networking wire protocol.
We added additional improvements and more RPCs to the start daemon and various services to continue to make chia start/stop reliable cross platform.
The install.sh script now discovers if it's running on Ubuntu less than 20.04 and correctly upgrades node.js to the current stable version.
For GitHub ci builds of the Windows installer, editbin.exe is more reliably found.
All installer ci builds now obtain version information automatically from setuptools_scm and convert it to an installer version number that is appropriate for the platform and type of release (dev versus release.)
We now codesign the Apple .dmg installer with the Chia Network developer ID on both GitHub Actions and Azure Pipelines. We will be notarizing and distributing the Azure Pipelines version as it's built on MacOS Mojave (10.14.6) for stronger cross version support.

Fixed

Having spaces in the path to a plot or temporary directory caused plotting to fail.
Changing keys will no longer interrupt plotting log.
1.6 introduced a bug where certain very many core machines would sync the blockchain very slowly.
The plotter log in the UI should scroll more reliably.
The plotter UI should display the correct log on all platforms
Starting chia now waits for the full node to be active before contacting the introducer.

[1.0beta6] aka Beta 1.6 - 2020-06-01

Added

Windows and MacOS now have one click installers that then send users to a GUI on both platforms to farm or use their wallets. Windows is built on GitHub Actions and MacOS is also built on Azure Pipelines so as to build on Mojave.
You can see and control your farmer, harvester, and plotter from the GUI on Windows, MacOS, and Linux.
Create plots and see the plotting log from a GUI on Windows, MacOS, and Linux.
You can now create or import private keys with a 24 word mnemonic, both in the UI and 'chia keys' command line.
You can delete and change active keys from the GUI and cli.
We added a new keychain system that replaces keys.yaml, and migrates existing users from keys.yaml. It utilizes each OS's keychain for slightly more secure key storage.
We added a chia keys command line program, to see, add, and remove private keys.
We added RPC servers and RPC client implementations for Farmer and Harvester. The new UI uses these for additional information and functionality.
We added total network storage space estimation to the node RPC at the /get_network_space endpoint instead of only being available in the cli. The RPC endpoint takes two block header hashes and estimates space between those header hashes.
Logs now autorotate. Once the debug.log reaches 20MB it is compressed and archived keeping 7 historical 20MB logs.
We now have a CHANGELOG.md that adheres closely to the Keep a Changelog standard. We merged in the version history and updated some previous release notes to capture items important to the change log. We are modifying our release process to accumulate changes at the top of the change log and then copy those to the release notes at the time of the release.
We added lgtm source analysis on pull request to the chia-blockchain, chiapos, chiavdf, chiabip158, and bls-library repositories to add some automated security analysis to our ci.

Changed

Due to an issue with aggsig and aggsig-me, the beta 1.6 blockchain is not compatible with earlier chains.
We replaced the Electron/JavaScript interface with a React user interface which is cleaner and more responsive.
We now have a multithreaded harvester to farm more plots concurrently. This is especially faster when there are multiple disks being harvested. The class is also made thread safe with mutex guards. This is achieved by releasing GIL in the python bindings when fetching qualities and proofs. We estimate that the former guidance of only 50 plots per physical drive should be updated to 250-350 plots per physical drive. We will continue to improve the plots per physical drive limit during the beta period.
Syncing a node is now much faster and uses less memory.
chia netspace has been refactored to use the /get_network_space RPC. The command syntax has changed slightly. By default it calculates the last 24 blocks from the current LCA. Optionally you can use the -b flag to start the calculation from a different block height. Use -d to specify the delta number of blocks back into history to estimate over from either LCA or your -b block height.
The Full node RPC response formats have been changed. All API calls now return a dict with success, and an additional value, for example {"success": True, "block": block}.
chiapos is now easier to compile with MSVC.
create plots now takes in an optional sk_seed, it is no longer read in from keys.yaml. If not passed in, it is randomly generated. The -i argument can now only be used when you provide an sk_seed.
Moved to PyYAML 5.3.1 which prevents arbitrary code execution during python/object/new constructor.
Moved to Python cryptography 2.9.2 which deprecates OpenSSL 1.0.1 and now relies upon OpenSSL 1.1.1g.
Moved to aiosqlite 0.13.0 which adds official support for Python 3.8 and fixes a possible hung thread if a connection failed.

Fixed

In beta 1.5 we introduced a bug in aggsig and aggsig-me that we have fixed in this release. That forced a hard fork of the chain so coins and balances are lost from beta 1.5. There is no impact on existing plots.
Starting and stopping servers now works much more reliably.
chia-check-plots uses the plot root and checks the plots in the same manner as harvester.
chia-check-plots now does not override plots.yaml, which means concurrent plots will properly be added to plots.yaml.
Fixed and issue where Relic and thus blspy would crash on processors older than Haswell as they don't support lzc.
Some non-critical networking errors are no longer logged.
Blocks with compact proofs of time are now able to be updated into the node database.
The install-timelord.sh script now correctly determines which version of python it is running under and correctly builds vdf_client and correctly links to vdf_bench. It also handles upgrading CMake on Ubuntu's older than 20.04LTS do satisfy the new CMake 3.14+ requirement to build Timelord.
An issue in asyncio was not being caught correctly and that could cause nodes to crash.
The build status shield layout is fixed in README.md
Raspberry Pi 3/4 with Ubuntu 20.04LTS 64 bit should compile again.

1.0beta5 aka Beta 1.5 - 2020-05-05

Added

This release is primarily a maintenance release for Beta 1.4.
We have added an option to chia-create-plots to specify the second temporary directory. Creating a plot is a three step process. First a working file ending in .dat.tmp is created. This file is usually 5 times larger than the final plot file. In the later stages of plotting a second temp file is created ending in .dat.2.tmp which will grow to the size of the final plot file. In the final step, the .dat.2.tmp is copied to the final .dat plot file. You can now optionally set the directory for the .dat.2.tmp file with the -2 flag. An example use case is plotting on a ramdisk and writing both the second temp file and the final file out to an SSD - chia-create-plots -n 1 -k 30 -t /mnt/ramdisk -2 /mnt/SSD -d /mnt/SSD.

Changed

chia init properly migrates from previous versions including the k>=32 workaround. Additionally, the farming target key is checked to make sure that it is the valid and correct public key format.
We have implemented a workaround for the chia start issues some were having upon crash or reboot. We will be rebuilding start and stop to be robust across platforms.
This release re-includes chia-start-harvester.
Coloured coins now have a prefix to help identify them. When sending transactions, the new prefix is incompatible with older clients.
The user interface now refers to chia coins with their correct currency code of XCH.
The next release will now be in the dev branch instead of the e.g. beta-1.5. Additionally we are enforcing linear merge into dev and prefer rebase merges or partial squash merges of particularly chatty commit histories.
Building the sub reposities (chiapos, chiavdf, blslibrary) now requires CMake 3.14+.

Fixed

There was a regression in Chia Proof of Space (chiapos) that came from our efforts to speed up plotting on Windows native. Now k>=32 plots work correctly. We made additional bug fixes and corrected limiting small k size generation.
There was a bug in Timelord handling that could stop all VDF progress.

Deprecated

We have made significant changes to the full node database to make it more reliable and quicker to restart. This requires re-syncing the current chain. If you use chia init then sync on first start will happen automatically. "$CHIA_ROOT" users will need to delete $CHIA_ROOT/db/* before starting Beta 1.5. This also fixes the simulation issue in Beta 1.4 where tips could go "back in time."

Known issues

uPnP support on Windows may be broken. However, Windows nodes will be able to connect to other nodes and, once connected, participate fully in the network.
Currently, there is no way to restore a Coloured Coin Wallet.

1.0beta4 aka Beta 1.4 - 2020-04-29

Added

This release adds Coloured coin support with offers. Yes that is the correct spelling. Coloured coins allow you to issue a coin, token, or asset with nearly unlimited issuance plans and functionality. They support inner smart transactions so they can inherit any of the other functionality you can implement in Chialisp. Offers are especially cool as they create a truly decentralized exchange capability. Read much more about them in Bram's blog post on Coloured coins.
This release adds support for native Windows via a (mostly) automated installer and MacOS Mojave. Windows still requires some PowerShell command line use. You should expect ongoing improvements in ease of install and replication of the command line tools in the GUI. Again huge thanks to @dkackman for continued Windows installer development. Native Windows is currently slightly slower than the same version running in WSL 2 on the same machine for both block verification and plotting.
We made some speed improvements that positively affected all platforms while trying to increase plotting speed in Windows.
The graphical Full Node display now shows the expected finish times of each of the prospective chain tips.
Now you can run estimates of the total space currently farming the network. Try chia netspace -d 12 to run an estimate over the last 12 blocks which is approximately 1 hour.
We’ve added TLS authentication for incoming farmer connections. TLS certs and keys are generated during chia init and only full nodes with your keys will be able to connect to your Farmer. Also, Harvester, Timelord, and Wallet will now not accept incoming connections which reduces the application attack surface.
The node RPC has a new endpoint get_header_by_height which allows you to retrieve the block header from a block height. Try chia show -bh 1000 to see the block header hash of block 1000. You can then look up the block details with chia show -b f655e1a9f7f8c89a703e40d9ce82ae33508badaf7b37fa1a56cad27926b5e936 which will look up a block by it's header hash.
Our Windows binaries check the processor they are about to run on at runtime and choose the best processor optimizations for our MPIR VDF dependency on Windows.
Most of the content of README.md and INSTALL.md have been moved to the repository wiki and placed in INSTALL and Quick Start Guide
Harvester is now asynchronous and will better be able to look up more plots spread across more physical drives.
Full node startup time has been sped up significantly by optimizing the loading of the blockchain from disk.

Changed

Most scripts have been removed in favor of chia action commands. You can run chia version or chia start node for example. Just running chia will show you more options. However chia-create-plots continues to use the hyphenated form. Also it's now chia generate keys as another example.
Chia start commands like chia start farmer and chia stop node now keep track of process IDs in a run/ directory in your configuration directory. chia stop is unlikely to work on Windows native for now. If chia start -r node doesn't work you can force the run/ directory to be reset with chia start -f node.
We suggest you take a look at our Upgrading documentation if you aren't performing a new install.
blspy now has libsodium included in the MacOS and Linux binary wheels.
miniupnpc and setprotitle were dynamically checked for an installed at runtime. Removed those checks and we rely upon the install tools installing them before first run.
Windows wheels that the Windows Installer packages are also available in the ci Artifacts in a .zip file.
The script chia start wallet-gui has been chaned to chia start wallet which launches but the GUI and server on MacOS and Linux. chia start wallet-server remains for WSL 2 and Windows native.

Deprecated

This release breaks the wire protocol so it comes with a new chain. As we merged in Coloured coins we found that we needed to change how certain hashes were managed. Your 1.0beta3 coin balances will be lost when you upgrade but your plots will continue to work on the 1.0beta4 chain. Since we had to make a breaking wire protocol change we accelerated changing our hash to prime function for starting proofs of time. That was also going to be a future breaking change.

Known issues

Plots of k>=32 are not working for farming, and some broken plots can cause a memory leak. A workaround is available.
If you are running a simulation, blockchain tips are not saved in the database and this is a regression. If you stop a node it can go back in time and cause an odd state. This doesn't practically effect testnet participation as, on restart, node will just sync up a few blocks to the then current tips.
uPnP support on Windows may be broken. However, Windows nodes will be able to connect to other nodes and, once connected, participate fully in the network.
Coins are not currently reserved as part of trade offers and thus could potentially be spent before the offer is accepted resulting in a failed offer transaction.
Currently, there is no way to restore a Coloured Coin Wallet.
The chia stop all command sometimes fails, use chia-stop-all instead. In windows, use the task manager to stop the servers.

1.0beta3 aka Beta 1.3 - 2020-04-08

Added

Windows, WSL 2, Linux and MacOS installation is significantly streamlined. There is a new Windows installer for the Wallet GUI (huge thanks to @dkackman).
All installs can now be from the source repository or just the binary dependencies on WSL 2, most modern Linuxes, and MacOS Catalina. Binary support is for both Python 3.7 and 3.8.
There is a new migration tool to move from Beta1 (or 2) to Beta3. It should move everything except your plots.
There is a new command chia init that will migrate files and generate your initial configuration. If you want to use the Wallet or farm, you will also have to chia-generate-keys. You can read step by step instructions for upgrading from a previous beta release. If you've set $CHIA_ROOT you will have to make sure your existing configuration remains compatible manually.
Wallet has improved paper wallet recovery support.
We now also support restoring old wallets with only the wallet_sk and wallet_target. Beta3's Wallet will re-sync from scratch.
We've made lots of little improvements that should speed up node syncing
We added full block lookup to chia show.

Changed

chia-restart-harvester has been renamed from chia-start-harvester to better reflect its functionality. Use it to restart a harvester that's farming so that it will pick up newly finished plots.
We made the Wallet configurable to connect to a remote trusted node.
We now have farmers reconnect to their trusted node if they lose contact.
We updated our miniupnpc dependency to version 2.1.
We increase the default farmer propagate threshold to reduce chain stall probability.

Deprecated

You should not copy over any prior Wallet database as they are not compatible with Beta3. Your existing full node will not have to re-sync and its database remains compatible.

Fixed

Among a lot of bug fixes was removing a regression that slowed plotting on MacOS by 3 times and may have had smaller impacts on plotting speed on other platforms.
We've removed some race conditions in the Wallet
We resolved the "invalid blocks could disconnect farmers" bug
We and upped the default tls certificate size to 2048 for some unhappy operating systems.

Known issues

Windows native is close but not here yet. Also, we should be adding back MacOS Mojave support shortly.
So why is this Beta 3 you're wondering? Well, we're getting used to our new release management tools and a hotfix devoured our beta2 nomenclature... We've marked it YANKED here.
If you previously used the plot_root variable in config, your plot directory names might not migrate correctly. Please double check the filenames in ~/.chia/beta-1.0b3/config/plots.yaml after migrating

1.0beta2 aka Beta 1.2 - 2020-04-04 [YANKED]

1.0beta1 aka Beta 1.0 - 2020-04-02

Added

There is now full transaction support on the Chia blockchain. In this initial Beta 1.0 release, all transaction types are supported though the wallets and UIs currently only directly support basic transactions like coinbase rewards and sending coins while paying fees. UI support for our smart transactions will be available in the UIs shortly.
Wallet and Node GUI’s are available on Windows, Mac, and desktop Linux platforms. We now use an Electron UI that is a full light client wallet that can also serve as a node UI. Our Windows Electron Wallet can run standalone by connecting to other nodes on the network or another node you run. WSL 2 on Windows can run everything except the Wallet but you can run the Wallet on the native Windows side of the same machine. Also the WSL 2 install process is 3 times faster and much easier. Windows native node/farmer/plotting functionality are coming soon.
Install is significantly easier with less dependencies on all supported platforms.
If you’re a farmer you can use the Wallet to keep track of your earnings. Either use the same keys.yaml on the same machine or copy the keys.yaml to another machine where you want to track of and spend your coins.
We have continued to make improvements to the speed of VDF squaring, creating a VDF proof, and verifying a VDF proof.

Changed

We have revamped the chia management command line. To start a farmer all you have to do is start the venv with . ./activate and then type chia-start-farmer &. The README.md has been updated to reflect the new commands.
We have moved all node to node communication to TLS 1.3 by default. For now, all TLS is unauthenticated but certain types of over the wire node to node communications will have the ability to authenticate both by certificate and by inter protocol signature. Encrypting over the wire by default stops casual snooping of transaction origination, light wallet to trusted node communication, and harvester-farmer-node communication for example. This leaves only the mempool and the chain itself open to casual observation by the public and the various entities around the world.
Configuration directories have been moved to a default location of HomeDirectory/.chia/release/config, plots/ db/, wallet/ etc. This can be overridden by export CHIA_ROOT=~/.chia for example which would then put the plots directory in HomeDirectory/.chia/plots.
The libraries chia-pos, chia-fast-vdf, and chia-bip-158 have been moved to their own repositories: chiapos, chiavdf, and chaibip158. They are brought in by chia-blockchain at install time. Our BLS signature library remains at bls-signatures.
The install process now brings in chiapos, chiavdf, etc from Pypi where they are auto published via GitHub Actions ci using cibuildwheel. Check out .github/workflows/build.yml for build methods in each of the sub repositories.
chia-regenerate-keys has been renamed chia-generate-keys.
setproctitle is now an optional install dependency that we will continue to install in the default install methods.
The project now defaults to venv without the proceeding . to better match best practices.
Developer requirements were separated from the actual requirements.
install-timelord.sh has been pulled out from install.sh. This script downloads the source python package for chiavdf and compiles it locally for timelords. vdf_client can be included or excluded to make building normal user wheels easier.

Removed

The Beta release is not compatible with the history of the Alpha blockchain and we will be ceasing support of the Alpha chain approximately two weeks after the release of this Beta. However, your plots and keys are fully compatible with the Beta chain. Please save your plot keys! Examples of how to save your keys and upgrade to the Beta are available on the repo wiki.
The ssh ui and web ui are removed in favor of the cli ui and the Electron GUI. To mimic the ssh ui try chia show -s -c and try chia show --help for usage instructions.
We have removed the inkfish vdf implementation and replaced it with the pybind11 C++ version.

Known Issues

Wallet currently has limited support for restoring from a paper wallet. Wallet uses hierarchically deterministic keys, and assumes that any keys that are at index "higher than one" have not been used yet. If you have received a payment to an address associated with a key at a higher index and you want it to appear in Wallet, the current work around is to press the "NEW ADDRESS" button multiple times shortly after sync start. That will make wallet "aware of" addresses at higher indexes. Full support for paper wallet restoration will be added soon.
We. Don't... Have.. Windows.... Native. YET!?! But the entire project is compiling on Windows 10 natively. Assistance would be more than appreciated if you have experience building binary python wheels for Windows. We are pushing some limits like uint-128, avx-2, avx-512, and AES-NI so it's not as easy as it looks...

Alpha 1.5.1 - 2020-03-24

Fixed

Fixed a bug in harvester that caused plots not to be farmed.

Alpha 1.5 - 2020-03-08

Added

You can now provide an index to create_plots using the -i flag to create an arbitrary new plot derived from an existing plot key. Thanks @xorinox.
There is a new restart_harvester.sh in scripts/ to easily restart a harvester when you want to add a newly completed plot to the farm without restarting farmer, fullnode, timelord, etc.
Harvesters now log errors if they encounter a malformed or corrupted plot file. Again thanks @xorinox.
New AJAX based full node UI. To access go to http://127.0.0.1:8555/index.html with any modern web browser on the same machine as the full node.
If you want to benchmark your CPU as a VDF you can use vdf_bench square_asm 500000 for the assembly optimized test or just vdf_bench square 500000 for the plain C++ code path. This tool is found in lib/chiavdf/fast_vdf/.
Improvements to shutting down services in all of the scripts in scripts/. Another @xorinox HT.

Changed

VDF verification code is improved and is now more paranoid.
Timelords can now be run as a cluster of VDF client instances around a central Timelord instance.. Instructions are available in the Cluster Timelord section of the repo wiki.

Fixed

Thanks @dkackman for clean ups to the proof of space code.
Thanks to @davision for some typo fixes.

Alpha 1.4.1 - 2020-03-06

Fixed

Stack overflow in verifier

Alpha 1.4 - 2020-02-19

Added

Compiling and execution now detect AES-NI, or a lack of it, and fall back to a software AES implementation.
Software AES adds support for Raspberry Pi 4, related ARM processors and Celeron processors.
Added install instructions for CentOS/RHEL 8.1.
Plotting working directory and final directory can both be specified in config.yaml
Proof of space binary and create_plots scripts now allows passing in temp and final directories.
Plotting now logs a timestamp at each major step.
Added support for Python 3.8.

Changed

Due to changes to the sqlite database that are not backwards compatible, re-synch will be required.
Loading the blockchain only loads headers into memory instead of header blocks (header + proofs), speeds up the startup, and reduces normal operation memory usage by 80%.
Memory access is now synchronous to reduce use of locks and speed up block processing.
Chia fullnode, farmer and harvester now default to logging to chia.log in the chia-blockchain directory. This is configured in config.yaml and due to config.yaml changes it is recommended to edit the new template config instead of using older config.yaml’s from previous versions.
uvloop is now an optional add on.
Harvester/farmer will not try to farm plots that they don’t have the key for.

Fixed

Thanks to @A-Caccese for fixes to Windows WSL instructions.
Thanks @dkackman who also fixed some compiler warnings.

Alpha 1.3 - 2020-01-21

Added

FullNode performance improvements - Syncing up to the blockchain by importing all blocks is faster due to improvements in VDF verification speed and multithreading block verification.
VDF improvements - VDF verification and generation speed has increased and dependence on flint2 has been removed. We wish to thank Dr. William Hart (@wbhart) for dual licensing parts of his contributions in FLINT and Antic for inclusion in the Chia blockchain.
Implemented an RPC interface with JSON serialization for streamables - currently on port 8555.
Added details on how to contribute in CONTRIBUTING.md. Thanks @RichardLitt.
Added color logging
Now chia_harvester will periodically announce which plots it is currently farming and their k sizes.

Changed

Moved the ssh UI to use RPC.
Changed the displayed process names for harvester, farmer, fullnode, timelords, and VDFs to to chia_full node, chia_harvester, etc. Fixed a bug that could cause inadvertent shutdown of other processes like an ongoing plotting session when new chia services were started.
Clarified the minimum version of boost required to build timelord/VDFs. Hat tip @AdrianScott
Consensus and related documentation moved to the repository wiki.

Fixed

Fixed a bug where the node may not sync if it restarts close to a tip.
Fixed a typo in the UI. Hat tip to @lvcivs for the pr.
Fixed a memory leak in qfb_nudupl.
Lots of smaller bug and documentation fixes.

Removed

Mongodb removed and replaced with SQLite for the blockchain database. This will require nodes to re-sync with the network. Luckily this is now faster.

Alpha 1.2 - 2020-01-08

Added

Performance improvements
- Removes database access from blockchain, and handles headers instead of blocks
- Avoid processing blocks and unfinished blocks that we have already seen.
- Also adds test for load.

Changed

Improvements to plotting via lookup table - as much as 15% faster

Fixed

Fixed a blockchain initialization bug

Alpha 1.1.1 - 2019-12-25

Added

Added install instructions for Windows using WSL and Ubuntu.
Added install instructions for CentOS 7.7.

setuptools_scm was corrupting .zip downloads of the repository.

Alpha 1.1 - 2019-12-12

Added

Introducer now makes sure it only sends peer addresses to peers of peers that it can reach on port 8444 or their UPnP port.
We are now using setuptools_scm for versioning.

Changed

Timelord VDF submission and management logic upgraded.

Fixed

FullNode: A long running or low ulimit situation could cause an “out of files” issue which would stop new connection creation. Removed the underlying socket leak.
FullNode: Multiple SSH UI bugs fixed.
Harvester: Farming a plot of k = 30 or greater could lead to a segfault in the harvester.
Updated blspy requirement to address an issue in the underlying bls-signatures library.

Alpha 1.0 - 2019-12-05
