Performance Enhancements:
* Many micro-optimizations result in 20.3% more work for the same number of CPU cycles relative to the previous release. The cumulative performance increase since version 3.8.0 is 61%. (Measured using cachegrind on the speedtest1.c workload on Ubuntu 13.10 x64 with gcc 4.8.1 and -Os. Your performance may vary.)
* The sorter can use auxiliary helper threads to increase real-time response. This feature is off by default and may be enabled using the PRAGMA threads command or the SQLITE_DEFAULT_WORKER_THREADS compile-time option.
* Enhance the skip-scan optimization so that it is able to skip index terms that occur in the middle of the index, not just as the left-hand side of the index.
* Improved optimization of CAST operators.
* Various improvements in how the query planner uses sqlite_stat4 information to estimate plan costs.
New Features:
* Added new interfaces with 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_result_blob64(), sqlite3_bind_text64(), and sqlite3_result_text64().
* Added the new interface sqlite3_msize() that returns the size of a memory allocation obtained from sqlite3_malloc64() and its variants.
* Added the SQLITE_LIMIT_WORKER_THREADS option to sqlite3_limit() and PRAGMA threads command for configuring the number of available worker threads.
* The spellfix1 extension allows the application to optionally specify the rowid for each INSERT.
* Added the User Authentication extension.
Bug Fixes:
* Fix a bug in the partial index implementation that might result in an incorrect answer if a partial index is used in a subquery or in a view.
* Fix a query planner bug that might cause a table to be scanned in the wrong direction (thus reversing the order of output) when a DESC index is used to implement the ORDER BY clause on a query that has an identical GROUP BY clause.
* Fix a bug in sqlite3_trace() that was causing it to sometimes fail to print an SQL statement if that statement needed to be re-prepared.
* Fix a faulty assert() statement.

Intented as a clean implementation (replacement) of wip/mysql-sphinxse.
SphinxSE is MySQL storage engine which can be compiled into MySQL server 5.x
using its pluggable architecture. Despite the name, SphinxSE does not
actually store any data itself. It is actually a built-in client which
allows MySQL server to talk to searchd, run search queries, and obtain
search results. All indexing and searching happen outside MySQL.
See http://sphinxsearch.com/docs/current.html#sphinxse-overview
Peewee is a simple and small ORM. It has few (but expressive)
concepts, making it easy to learn and intuitive to use.
Supports SQLite, MySQL and PostgreSQL.

Fixed a bug that DB_ENV->log_get_config did not work correctly before DB_ENV->open.
Fixed a bug that could cause a SQL build failure when FTS3 is enabled.
Fixed a bug that prevented in-memory SQL database from being created properly. They can now be created without the use of the SQLITE_OPEN_CREATE flag.
Fixed a memory leak in SQL online backup.
Added additional examples for C++
Fixed a bug that could make odbc fail to build with sqlite source code.
Fixed bugs in compaction of large keys in the upper levels of btrees.
The db utilities (db_xxxx) no longer operate on replication clients that are being automatically initialized. The DB_REP_LOCKOUT error is now returned.
Using DB_TXN_SNAPSHOT on an HA client will now result in an error.
Fixed a bug that prevented a sub-database from being created under the directory identified in DB->set_create_dir.
Fixed a race condition on a cursor when using a multi-threaded application with the SQL API.
Fixed a race condition in the failchk code when cleaning up mutexes.
Fixed a resource leak in the db->verify() function for btrees. The bug would slow down verification and possibly cause it to run out of memory.

* Fixed a bug with the bytearray support introduced in 2.10.2. Thanks
Josh Owen.
* 2.10.2
* Added support for Hiredis's new bytearray support. Thanks
https://github.com/tzickel
* POSSIBLE BACKWARDS INCOMPATBLE CHANGE: Fixed a possible race condition
when multiple threads share the same Lock instance with a timeout. Lock
tokens are now stored in thread local storage by default. If you have
code that acquires a lock in one thread and passes that lock instance to
another thread to release it, you need to disable thread local storage.
Refer to the doc strings on the Lock class about the thread_local
argument information.
* Fixed a regression in from_url where "charset" and "errors" weren't
valid options. "encoding" and "encoding_errors" are still accepted
and preferred.
* The "charset" and "errors" options have been deprecated. Passing
either to StrictRedis.__init__ or from_url will still work but will
also emit a DeprecationWarning. Instead use the "encoding" and
"encoding_errors" options.
* Fixed a compatability bug with Python 3 when the server closes a
connection.
* Added BITPOS command. Thanks https://github.com/jettify.
* Fixed a bug when attempting to send large values to Redis in a Pipeline.
A new libmongoc-priv.so library is installed that does not have symbols
hidden. You can access private headers via the -private.h variants. This
means you will need to recompile your project every time the library is
changed (if you use those private headers, as they are subject to change).
For other minor changes, see commits made since 0.98.0:
https://github.com/mongodb/mongo-c-driver/compare/0.98.0...1.0.0
--[ Redis 2.8.17 ] Release date: 19 Sep 2014
# UPGRADE URGENCY: HIGH for Redis Sentinel.
LOW for Redis Server (unmodified compared to 2.8.16).
* [FIX] Resolved a memory leak in the hiredis library causing a memory leak
in Redis Sentinel when a monitored instance or another Sentinel is
unavailable. Every reconnection attempt will leak a small amount of
memory, but in the long run the process can reach a considerable size.
--[ Redis 2.8.16 ] Release date: 16 Sep 2014
# UPGRADE URGENCY: HIGH for Redis if you are using 2.8.15 + AOF.
LOW for Sentinel.
* [FIX] The ability to load truncated AOF files introduced with Redis 2.8.15
contains a bug fixed in this release: after loading the file was not
truncated to the last valid command, so the new commands are appended
after a non well formed command. This means that:
1) The first AOF rewrite triggered by the server will automatically
fix the problem.
2) However, if the server is restarted before the rewrite, Redis may
not be able to load the file and you need to manually fix it.
In order to fix a corrupted file you should start the redis-check-aof
utility WITHOUT the --fix option, just to check the offset where the
corruption is found. Around the offset reported by the check utility
you'll find, inside your AOF file, a command which is not complete
according to the Redis protocol. Just remove this incomplete command
leafing the file unaltered before and after the offending command,
and restart the server.
IMPORTANT #1: Redis 2.8.15 is the only stable version of Redis with
this bug so probably no actual real-world problem happened since the
problem is automatically fixed at the first automatic AOF rewrite.
IMPORTANT #2: Before upgrading to Redis 2.8.16, if you are using Redis
2.8.15 with AOF enabled, make sure to trigger a manual AOF rewrite
using the BGREWRITEAOF command.
* [FIX] SAVE is no longer propagated to AOF / slaves.
--[ Redis 2.8.15 ] Release date: 12 Sep 2014
# UPGRADE URGENCY: LOW for Redis, HIGH for Sentinel.
* [FIX] Sentinel critical bug fixed: the absolute majority was computed in a
wrong way because of a programming error. Now the implementation does
what the specification says and the majority to authorize a failover
(that should not be confused with the ODOWN quorum) is the majority of
*all* the Sentinels ever seen for a given master, regardless of their
current state.
* [FIX] GETRANGE test no longer fails for 32 bit builds (Matt Stancliff).
* [FIX] Limit SCAN latency when the hash table is in an odd state (very few
populted buckets because rehashing is in progress). (Xiaost and
Salvatore Sanfilippo)
* [NEW] Redis is now able to load truncated AOF files without requiring a
redis-check-aof utility run. The default now is to load truncated
(but apparently not corrupted) AOFs, you can change this in redis.conf.
(Salvatore Sanfilippo).
* [NEW] Sentinel: ability to announce itself with an arbitrary IP/port to work
in the context of natted networks. However this is probably still
not enough since there is no equivalent mechanism for slaves listed
in the master INFO output. (Dara Kong and Salvatore Sanfilippo)
--[ Redis 2.8.14 ] Release date: 1 Sep 2014
# UPGRADE URGENCY: HIGH for Lua scripting users, the server could crash because
of a bug introduced in Redis 2.8.10, otherwise LOW.
LOW for Redis Sentinel.
* [FIX] Don't prevent use of shared integers if maxmemory policy is non-LRU.
(Salvatore Sanfilippo)
* [FIX] Fail SYNC if background save child aborted due to a signal.
(Yossi Gottlieb)
* [FIX] Different small redis-cli fixes. (Dov Murik, Charsyam, cubicdaiya,
Kashif Rasul, Jan-Erik Rediger, Matt Stancliff)
* [FIX] AIX compilation fixes. (Siah Lyimo)
* [FIX] A number of other smaller issues.
* [FIX] Improved SIGINT handling (Matt Stancliff, Salvatore Sanfilippo)
* [FIX] Use unsigned types in SDS header to raise limit to 4GB.
(Matt Stancliff, Salvatore Sanfilippo)
* [FIX] Handle signed/unsigned comparisons with more care around the code.
(Salvatore Sanfilippo)
* [FIX] Colorized test output fixed to don't change the background color.
(Mariano Pérez Rodríguez)
* [FIX] More Sentinel IPv6 fixes. (Eiichi Sato)
* [FIX] Deny CLIENT command in scripts. (Matt Stancliff)
* [FIX] Allow datasets with more than 2 billion of keys, initial work.
* [FIX] Fix a Lua scripting crash by storing the length of the static
argv when first allocated. (Paddy Byers)
* [NEW] Pub/Sub PING. (Salvatore Sanfilippo)
* [NEW] Much faster ZUNIONSTORE. (Kyle Hubert, Salvatore Sanfilippo)
* [NEW] Faster ll2string() implementation. (Salvatore Sanfilippo)
* [NEW] **WARNING, minor API change**: PUBSUB NUMSUB: return type modified
to integer. (Matt Stancliff)
* [NEW] redis-benchmark support for AUTH. (CharSyam)

Version 3.4.2 Released September 25, 2015 (git commit 61440e1f4ccb6c293c5838676da1942e0df67271)
- Fix bug where single-quoted type arguments to the table_info()
method were causing a SQL error.
[Greg Sabino Mullane] (CPAN bug #99144)
InnoDB: An ALTER TABLE ... ADD FOREIGN KEY operation could cause a serious error.
InnoDB: With a transaction isolation level less than or equal to READ COMMITTED, gap locks were not taken when scanning a unique secondary index to check for duplicates. As a result, duplicate check logic failed allowing duplicate key values in the unique secondary index.
InnoDB: During recovery, a segmentation fault would occur when marking a table as corrupt.
yaSSL client code did not validate the encryption size or session ID length, which could cause the client to exit.
MySQL installation from RPM packages could fail if Postfix had been installed using yum.
yaSSL could fail preauthorization if the client supplied inaccurate buffer lengths.
Competition between threads could lead to timeout failure trying to rotate the audit log file.
On Linux (OEL6), if Sun DTrace was installed, the MySQL build failed.
LPAD() and RPAD() could cause a server exit if the pad string argument was not well formed.
The optimizer could create a zero-length column for a temporary table, causing a server exit.
The --skip-innodb option is now deprecated and its use results in a warning. It will be removed in a future MySQL release. This also applies to its synonyms (--innodb=OFF, --disable-innodb, and so forth).
MySQL Enterprise Edition now includes a set of encryption functions based on the OpenSSL library that expose OpenSSL capabilities at the SQL level.
Replication: The new variable simplified_binlog_gtid_recovery can be used to change the way binary log files are searched for previous GTIDs during recovery, speeding up the process when a large number of binary log files exist.
Internally, spatial data types such as Geometry are represented as BLOB values, so when invoked with the --hex-blob option, mysqldump now displays spatial values in hex.

PostGIS adds support for geographic objects to the PostgreSQL object-relational
database. In effect, PostGIS "spatially enables" the PostgreSQL server,
allowing it to be used as a backend spatial database for geographic information
systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS
follows the OpenGIS "Simple Features Specification for SQL" and has been
certified as compliant with the "Types and Functions" profile.
PostGIS/PostgreSQL includes the following functionality:
* Simple Features as defined by the OpenGIS Consortium (OGC)
* Support for Well-Known Text and Well-Known Binary representations of GIS
objects
* Fast spatial indexing using GiST
* Geospatial analysis functions
* PostgreSQL JDBC extension objects corresponding to the geometries
* Support for OGC access functions as defined by the Simple Features
Specification
This is postgis 2.x, the currently-maintained and recommended version.
