Upgrade urgency CRITICAL ONLY for Redis Cluster users. Otherwise no reason
to upgrade at all.
Redis 4.0.8 fixes a single critical bug in the radix tree data structure
used for Redis Cluster keys slot tracking. The problem was actually fixed
10 months ago into unstable, but it was fixed in a commit related to Streams
so it was never backported (for error) into the 4.0 branch.
The problem will crash Redis Cluster instances during deletions, but it is
very hard to trigger: only when the node removed is in the edge of a memory
mapped area there are the conditions to create an issue, because otherwise
the code just accesses an out of range word in read-only way in an allocated
structure: this is almost always harmless.

<ChangeLog>
* Many 32 bit overflows were addressed in order to allow to use Redis with
a very significant amount of data, memory size permitting. (zhaozhao.zz,
Oran Agra)
* MEMORY USAGE fixed for the list type. (gnuhpc)
* Allow read-only scripts in Redis Cluster. (Salvatore Sanfilippo)
* Fix AOF pipes setup in edge case. (heqin)
* AUTH option for MIGRATE. (AlexStocks, Salvatore Sanfilippo, Fabio Nicotra)
* HyperLogLogs are no longer converted from sparse to dense in order
to be merged. (Salvatore Sanfilippo)
* Fix AOF rewrite dead loop under edge cases. (heqin)
* Fix processing of large bulk strings (>= 2GB). (Oran Agra)
* Added RM_UnlinkKey in modules API. (Dvir Volk)
* Fix Redis Cluster crashes when certain commands with a variable number
of arguments are called in an improper way. (Salvatore Sanfilippo)
* Fix memory leak in lazyfree engine. (zhaozhao.zz)
* Fix many potentially successful partial synchronizations that end
doing a full SYNC, because of a bug destroying the replication
backlog on the slave. So after a failover the slave was often not able
to PSYNC with masters, and a full SYNC was triggered. The bug only
happened after 1 hour of uptime so escaped the unit tests. (Oran Agra)
* Improve anti-affinity in master/slave allocation for Redis Cluster
when the cluster is created. (Salvatore Sanfilippo)
* Improve output buffer handling for slaves, by not limiting the amount
of writes a slave could receive. (Guy Benoish)

Upgrade urgency LOW: This release mainly fixes a rare GEO API bug and a crash
related to the modules subsystem.
Redis 4.0.0-RC2 (version number 3.9.102) just fixes two bugs:
1. GEORADIUS could fail reporting items with very big radius lengths because
of a bug in the bounding box computation function. This was fixed and tests
with large radius sizes were added.
2. There was a crash in the modules subsystem that was not merged into RC1 for
an error, while it was already fixed into the "unstable" branch.

--[ Redis 3.0.7 ] Release date: 28 jan 2016
Upgrade urgency MODERATE: this release fixes important Redis Cluster bugs.
* [FIX] avg_ttl reporting in INFO improved. (Salvatore Sanfilippo)
* [FIX] Redis Cluster address update (via gossip section) processing improved
to avoid initiating inwanted handshakes.
* [FIX] Many fixes to MIGRATE multiple keys implementation. The command
could handle errors in a faulty way leading to crashes or other
unexpected behaviors. MIGRATE command refactoring.
(The analysis of the faulty conditions was conducted by
Kevin McGehee. The fix was developed by Salvatore Sanfilippo)
* [FIX] A Redis Cluster node crash was fixed because of wrong handling of
node->slaveof pointers.
(Reported by JackyWoo, fixed by Salvatore Sanfilippo)
* [FIX] Fix redis-trib rebalance when nodes need to be left empty because
the specified weight is zero.
(Reported by Shahar Mor, fixed by Salvatore Sanfilippo)
* [FIX] MIGRATE: Never send -ASK redirections for MIGRATE when there are
open slots. Redis-trib and other cluster management utility must
always be free to move keys between nodes about open slots, in order
to reshard, fix the cluster configuration, and so forth.
(Salvatore Sanfilippo)
* [FIX] Redis-trib is now able to fix more errors. A new CLUSTER subcommand
called BUMPEPOCH was introduced in order to support new modes
for the "fix" subcommand. (Salvatore Sanfilippo)
* [NEW] Cluster/Sentinel tests now use OSX leak to perform leak detection
at the end of every unit. (Salvatore Sanfilippo)
* [NEW] Detect and show server crashes during Cluster/Sentinel tests.
(Salvatore Sanfilippo)
* [NEW] More reliable Cluster/Sentinel test becuase of timing errors and
-LOADING errors. (Salvatore Sanfilippo)
--[ Redis 3.0.6 ] Release date: 18 Dec 2015
Upgrade urgency: MODERATE. We fixed a crash that happens very rarely, so
updating does not hurt, but most users are unlikely to
experience this condition because it requires some odd
timing. However if you are a Redis Cluster user, upgrading
is strongly adviced since this release includes very
important improvements to Redis Cluster.
* [FIX] lua_struct.c/getnum security issue fixed. (Luca Bruno discovered it,
patched by Sun He and Chris Lamb)
* [FIX] Redis Cluster replica migration fixed. See issue #2924 for details.
(Salvatore Sanfilippo)
* [FIX] Fix a race condition in processCommand() because of interactions
with freeMemoryIfNeeded(). Details in issue #2948 and especially
in the commit message d999f5a. (Race found analytically by
Oran Agra, patch by Salvatore Sanfilippo)
* [NEW] Backported from the upcoming Redis 3.2:
MIGRATE now supports an extended multiple-keys pipelined mode, which
is an order of magnitude faster. Redis Cluster now uses this mode
in order to perform reshardings and rebalancings. (Salvatore Sanfilippo)
* [NEW] Backported from the upcoming Redis 3.2:
Redis Cluster has now support for rebalancing via the redis-trib
rebalance command. Demo here:
https://asciinema.org/a/0tw2e5740kouda0yhkqrm5790
Official documentation will be available ASAP. (Salvatore Sanfilippo)
* [NEW] Redis Cluster redis-trib.rb new "info" subcommand.
* [NEW] Redis Cluster tests improved. (Salvatore Sanfilippo)
* [NEW] Log offending memory access address on SIGSEGV/SIGBUS (Salvatore
Sanfilippo)
</ChangeLog>
<ChangeLog>
--[ Redis 3.0.5 ] Release date: 15 Oct 2015
Upgrade urgency: MODERATE, the most important thing is a fix in the replication
code that may make the slave hanging forever if the master
remains with an open socket even if it is no longer able to
reply.
* [FIX] MOVE now moves the TTL as well. A bug lasting forever... finally
fixed thanks to Andy Grunwald that reported it.
(reported by Andy Grunwald, fixed by Salvatore Sanfilippo)
* [FIX] Fix a false positive in HSTRLEN test.
* [FIX] Fix a bug in redis-cli --pipe mode that was not able to read back
replies from the server incrementally. Now a mass import will use
a lot less memory, and you can use --pipe to do incremental streaming.
(reported by Twitter user @fsaintjacques, fixed by Salvatore
Sanfilippo)
* [FIX] Slave detection of master timeout. (fixed by Kevin McGehee, refactoring
and regression test by Salvatore Sanfilippo)
* [NEW] Cluster: redis-trib fix can fix an additional case for opens lots.
(Salvatore Sanfilippo)
* [NEW] Cluster: redis-trib import support for --copy and --replace options
(David Thomson)
</ChangeLog>
<ChangeLog>
Upgrade urgency: HIGH for Redis and Sentinel. However note that in order to
fix certain replication bugs, the replication internals were
modified in a very heavy way. So while this release is
conceptually saner, it may contain regressions. For this
reason, before the release, QA activities were performed by
me (antirez) and Redis Labs and no evident bug was found.
* [FIX] A number of bugs related to replication PSYNC and the (yet experimental)
diskless replication feature were fixed. The bugs could lead to
inconsistency between masters and slaves. (Salvatore Sanfilippo, Oran
Agra fixed the issue found by Yuval Inbar)
* [FIX] A replication bug in the context of PSYNC partial resynchonization was
found and fixed. This bug happens even when diskless replication is off
in the case different slaves connect at different times while the master
is creating an RDB file, and later a partial resynchronization is
attempted by a slave that connected not as the first one. (Salvatore
Sanfilippo, Oran Agra)
* [FIX] Chained replication and PSYNC interactions leading to potential stale
chained slaves data set, see issue #2694. (Salvatore Sanfilippo fixed
an issue reported by "GeorgeBJ" user at Github)
* [FIX] redis-cli --scan iteration fixed when returned cursor overflows
32 bit signed integer. (Ofir Luzon, Yuval Inbar)
* [FIX] Senitnel: fixed a bug during the master switch process, where for a
failed conditional check, the new configuration is rewritten, during
a small window of time, in a corrupted way where the master is
also reported to be one of the slaves. This bug is rare to trigger
but apparently it happens in the wild, and the effect is to see
a replication loop where the master will try to replicate with itself.
A detailed explanation of the bug and its effects can be found in
the commit message here:
c20218eb57.
The bug was found by Jan-Erik Rediger using a static analyzer and
fixed by Salvatore Sanfilippo.
* [FIX] Sentinel lack of arity checks for certain commands.
(Rogerio Goncalves, Salvatore Sanfilippo)
* [NEW] Replication internals rewritten in order to be more resistant to bugs.
The replication handshake in the slave side was rewritten as a non
blocking state machine. (Salvatore Sanfilippo, Oran Agra)
* [NEW] New "replication capabilities" feature introduced in order to signal
from the master to the slave what are the features supported, so that
the master can choose the kind of replication to start (diskless or
not) when master and slave are of different versions. (Oran Agra,
Salvatore Sanfilippo)
* [NEW] Log clients details when SLAVEOF command is received. (Salvatore
Sanfilippo with inputs from Nick Craver and Marc Gravell).
</ChangeLog>
<ChangeLog>
--[ Redis 3.0.3 ] Release date: 17 Jul 2015
Upgrade urgency: LOW for Redis and Sentinel.
* [FIX] Fix blocking operations timeout precision when HZ is at its default
value (not increased) and there are thousands of clients connected
at the same time. This bug affected Sidekiq users that experienced
a very long delay for BLPOP and similar commands to return for
timeout. Check commit b029ff1 for more info. (Salvatore Sanfilippo)
* [FIX] MIGRATE "creating socket: Invalid argument" error fix. Check
issues #2609 and #2612 for more info. (Salvatore Sanfilippo)
* [FIX] Be able to connect to the master even when the slave is bound to
just the loopback interface and has no valid public address in the
network the master is reacahble. (Salvatore Sanfilippo)
* [FIX] ZADD with options encoding promotion fixed. (linfangrong)
* [FIX] Reset aof_delayed_fsync on CONFIG RESETSTATS. (Tom Kiemes)
* [FIX] PFCOUNT key parsing in cluster fixed. (MOON_CLJ)
* [FIX] Fix Solaris compilation of Redis 3.0. (Jan-Erik Rediger)
* [NEW] Variadic EXISTS command. Now the command accepts multiple arguments
and returns the total count of existing keys.
</ChangeLog>
<ChangeLog>
--[ Redis 3.0.2 ] Release date: 4 Jun 2015
Upgrade urgency: HIGH for Redis because of a security issue.
LOW for Sentinel.
* [FIX] Critical security issue fix by Ben Murphy: http://t.co/LpGTyZmfS7
* [FIX] SMOVE reply fixed when src and dst keys are the same. (Glenn Nethercutt)
* [FIX] Lua cmsgpack lib updated to support str8 type. (Sebastian Waisbrot)
* [NEW] ZADD support for options: NX, XX, CH. See new doc at redis.io.
(Salvatore Sanfilippo)
* [NEW] Senitnel: CKQUORUM and FLUSHCONFIG commands back ported.

--[ Redis 3.0.0 RC6 (version 2.9.106) ] Release date: 24 mar 2015
Upgrade urgency: HIGH because of bugs related to Redis Custer and replication.
This is the 6th release candidate of Redis 3.0.0. This release fixes important
issues discovered during stress testing, and implements safest behavior
for blocking operations during clients reshardings, and a new much needed
functionality of Redis Cluster manual failovers.
In order to fix certain bugs quite a bit of refactoring was needed which
is usually non advisabble in a Release Candidate, but needed in order to
end with a clean fix.
>> General changes
* [FIX] Redis (non clustered & clustered) replication bug involving blocking
operations: see issue #2473. (Salvatore Sanfilippo)
>> Cluster changes
* [FIX] clientsArePaused() fix crashing the old master during manual failover.
(Salvatore Sanfilippo)
* [FIX] Lua scripts replication in Redis Cluster was totally broken.
(Salvatore Sanfilippo)
* [FIX] Redirect clients blocked into list operations when the hash slot
they are blocked into is migrated to another instance or the cluster
state turns into "fail". (Salvatore Sanfilippo)
* [NEW] TAKEOVER option for CLUSTER FAILOVER implemented. It is now possible
to fix a cluster manually in the minority side of the partition, for
example in order to allow for multi DC setups & recovery.
(Salvatore Sanfilippo)
>> Sentinel changes
No changes in Sentinel.
--[ Redis 3.0.0 RC5 (version 2.9.105) ] Release date: 20 mar 2015
Upgrade urgency: Moderate for Redis Cluster users, low otherwise.
This is the 5th release candidate of Redis 3.0.0, released in order to fix
a moderate bug in Redis Cluster. This RC does not shift in the future the
Redis 3.0.0 final release which is scheduled in a few days (we are in the
process of finishing the documentation for Redis Cluster).
>> General changes
* [FIX] Fix LATENCY command crash. (Salvatore Sanfilippo, thx to Ingmar)
* [FIX] Config: missing activerehashing option support in CONFIG SET added.
(Salvatore Sanfilippo, thx to Bill Anderson)
* [FIX] Fix for backtrace generation issue. (Mariano Pérez Rodríguez, Matt Stancliff, Salvatore Sanfilippo)
* [NEW] Redis-cli --latency-dist backported from unstable.
(Salvatore Sanfilippo)
>> Cluster changes
* [FIX] Avoid redundant SELECT in MIGRATE. (Tommy Wang, Salvatore Sanfilippo)
* [FIX] More robust slave check in CLUSTER REPLICATE. (Salvatore Sanfilippo)
* [FIX] Fixed possible Redis Cluster node crash due to wrong separation of
concerns between getNodeByQuery() and Cluster global state update
fnuction. (Salvatore Sanfilippo, thx to Ingmar)
* [NEW] Add command CLUSTER MYID to easily featch instance ID. (Michel Martens)
>> Sentinel changes
* [NEW] Support for CLIENT command added. It was missing in the command table.

--[ Redis 3.0.0 RC4 (version 2.9.104) ] Release date: 13 feb 2015
Upgrade urgency: High for Redis if you use LRU eviction, low otherwise.
This is the 4th release candidate of Redis 3.0.0, it fixes problems with
LRU eviction that are not present in older release (2.8.x is not affected)
and adds new tools to inspect latency and load-test LRU.
>> General changes
* [FIX] redis-cli CSV output NIL spurious newline removed. (Matt Collier)
* [FIX] Memory efficiency test in unit test is now much faster: it affacted
the total "make test" execution time in a bad way. (Salvatore
Sanfilippo)
* [FIX] Fixes and improvements to dict.c and LRU eviction. Redis 3.0.0 new
LRU eviction had bugs creating high latency spikes when LRU was
happening during the keys dictionary rehashing. This bug is not
present into 2.8, was 3.0 specific. As a side effect of this issue
dict.c is now improved, and LRU algorithm is more precise (better
approximates true LRU). This was a joint effort, see issue
#2306 for details. (Oran Agra, Sun He, Salvatore Sanfilippo).
Thanks to Charsyam for spotting an integer overflow.
* [NEW] New latency tool: redis-cli --latency-dist is able to show an
xterm-256 based spectrum of latencies over time. (Salvatore Sanfilippo)
* [NEW] redis-cli --lru-test implemented (cache workload simulator). (Salvatore
Sanfilippo)
* [NEW] redis-cli --stat now shows LOAD when Redis is loading data.
* [NEW] Support "1G" etc. units in CONFIG SET. (Chris Lamb, Salvatore
Sanfilippo)

Upgrade urgency: High for Redis Cluster users, Low otherwise.
This is the third release candidate for Redis 3.0.0, the new RC fixes
several critical issues with Redis Cluster.
>> General changes
* [FIX] AOF bug unlikely to happen in practice and mostly harmless: child
process segfaults when parent is not reachable via pipe. (Sun He)
* [FIX] Scripting engine now reports an error when misused with Lua debug
hooks, instead of crashing. (Salvatore Sanfilippo)
>> Cluster changes
* [FIX] Several issues with Redis Cluster internal nodes objects handling.
(Matt Stancliff & Salvatore Sanfilippo)
* [FIX] Improvements in the Cluster test.
(Matt Stancliff & Salvatore Sanfilippo).
* [FIX] Cluster memory leaks / double frees (Matt Stancliff).
* [FIX] /dev/urandom surrogate for generation of unique IDs in a more
cheap way. (Salvatore Sanfilippo)
* [FIX] Fixes and improvements to PING / PONG packets gossip sections
in order to improve (and fix) failure detection and speedup
cluster info propagation. (Salvatore Sanfilippo)
* [NEW] CLUSTER count-failure-reports command added. (Salvatore Sanfilippo)

--[ Redis 3.0.0 RC2 (version 2.9.102) ] Release date: 13 jan 2014
Upgrade urgency: LOW.
This is the second release candidate of Redis Cluster. The major changes
are back porting of things implemented into the unstable branch while
this was still possible (with the new development model adopted only
bug fixes will be merged in the future).
RC2 also fixes a few Redis Cluster non critical bugs.
>> General changes
* [FIX] A number of minor bug fixes.
* [NEW] Diskless replication backportede.
* [NEW] Lua bitops and updated cmsgpack backported.
* [NEW] Transparent Huge Pages warnings and reporting backported.
>> Cluster changes
* [FIX] Fix PUBLISH cluster bus message count field.
* [FIX] It is no longer possible to write outside node hash slots using Lua.
* [FIX] Valgrind warnings (no actual bugs).
* [FIX] Less strict in acceptiong myself->ip if it's not populated.
* [NEW] Better testing of Lua scripts.
>> Sentinel changes
No changes to Sentinel.
</ChangeLog>
<ChangeLog>
--[ Redis 3.0.0 RC1 (version 2.9.101) ] Release date: 9 oct 2014
This is the first release candidate of Redis Cluster.
>> General changes
* [FIX] An very large number of small fixes, old and new, merged in the
context of a the issue #1906. Please see the issue page here
for exact credits: https://github.com/antirez/redis/pull/1906
of each commit. (Matt Stancliff and many others).
* [FIX] SAVE is no longer propagated to AOF / slaves.
* [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] DEBUG POPULATE two args form implemented. It is now possible to
call it with DEBUG POPULATE <count> <prefix>. Default prefix
is "key:" as usually.
* [NEW] INCR: Modify incremented object in-place when possible. This results
in speed improvements + possibly better memory locality.
>> Cluster changes
* [FIX] Cluster: claim ping_sent time even if we can't connect.
* [FIX] redis-trib should not abort easily on connection issues.
* [FIX] Cluster test: less console-spammy resharding test.
* [FIX] Fix logic to detect we are among a minority.
* [FIX] Process gossip section only for known nodes.
* [NEW] Redis Cluster is stable and tested enough, there is a clear MVP,
so it was promoted from beta to stable.
* [NEW] New unit 09, Pub/Sub across the cluster.
* [NEW] New unit 08, update messages.
* [NEW] New cluster option to work with partial slots coverage.
* [NEW] More chatty cluster slaves when failover is stalled. They log reason
with rate limiting, only when reason changes or a given time
has elapsed.
>> Sentinel changes
* [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] 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.
* [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)

* [NEW] Faster ll2string() implementation. (Salvatore Sanfilippo)
>> Cluster changes
* [FIX] CLUSTER RESET: Flush slave dataset on reset. (Salvatore Sanfilippo)
* [FIX] Replica migration: don't migrate to masters that never had slaves
in the past, but only to masters that remained orphaned after
failure events. (Salvatore Sanfilippo)
* [NEW] redis-trib: allow to reshard in non-interactive way. (Salvatore
Sanfilippo)
* [NEW] Cluster test: unit 04, check consistency during resharding. (Salvatore
Sanfilippo)
* [NEW] Cluster test: unit 05, slave selection. (Salvatore Sanfilippo)
* [NEW] Cluster test: unit 06, slaves with stale data can't failover. (Salvatore
Sanfilippo)
