================================================================================
Redis 6.0.15 Released Wed Jul 21 16:32:19 IDT 2021
================================================================================

Upgrade urgency: SECURITY, contains fixes to security issues that affect
authenticated client connections on 32-bit versions. MODERATE otherwise.

Fix integer overflow in BITFIELD on 32-bit versions (CVE-2021-32761).
An integer overflow bug in Redis version 2.2 or newer can be exploited using the
BITFIELD command to corrupt the heap and potentially result with remote code
execution.

Bug fixes that involve behavior changes:
* Change reply type for ZPOPMAX/MIN with count in RESP3 to nested array (#8981).
  Was using a flat array like in RESP2 instead of a nested array like ZRANGE does.

Bug fixes:
* Fail EXEC command in case a watched key is expired (#9194)
* Fix SMOVE not to invalidate dest key (WATCH and tracking) when member already exists (#9244)
* Fix SINTERSTORE not to delete dest key when getting a wrong type error (#9032)
* Fix overflows on 32-bit versions in GETBIT, SETBIT, BITCOUNT, BITPOS, and BITFIELD (#9191)
* Set TCP keepalive on inbound cluster bus connections (#9230)
* Fix ziplist length updates on big-endian platforms (#2080)
* Fix diskless replica loading to recover from RDB short read on module AUX data (#9199)
* Fix race in client side tracking (#9116)
* If diskless repl child is killed, make sure to reap the child pid (#7742)
* Add a timeout mechanism for replicas stuck in fullsync (#8762)

CLI tools:
* redis-cli cluster import support source and target that require auth (#7994)
* redis-cli cluster import command may issue wrong MIGRATE command, sending COPY instead of REPLACE (#8945)
* redis-cli support for RESP3 set type in CSV and RAW output (#7338)

================================================================================
Redis 6.0.14 Released Tue June 1 12:00:00 IST 2021
================================================================================

Upgrade urgency: SECURITY, Contains fixes to security issues that affect
authenticated client connections. MODERATE otherwise.

Fix integer overflow in STRALGO LCS (CVE-2021-32625)
An integer overflow bug in Redis version 6.0 or newer can be exploited using the
STRALGO LCS command to corrupt the heap and potentially result with remote code
execution. This is a result of an incomplete fix by CVE-2021-29477.

Other bug fixes:
* Fix crash in UNLINK on a stream key with deleted consumer groups (#8932)
* SINTERSTORE: Add missing keyspace del event when none of the sources exist (#8949)

================================================================================
Redis 6.0.13 Released Mon May 3 19:00:00 IST 2021
================================================================================

Upgrade urgency: SECURITY, Contains fixes to security issues that affect
authenticated client connections. LOW otherwise.

Integer overflow in STRALGO LCS command (CVE-2021-29477):
An integer overflow bug in Redis version 6.0 or newer could be exploited using
the STRALGO LCS command to corrupt the heap and potentially result in remote
code execution. The integer overflow bug exists in all versions of Redis
starting with 6.0.

Integer overflow in COPY command for large intsets (CVE-2021-29478):
An integer overflow bug in Redis 6.2 could be exploited to corrupt the heap and
potentially result with remote code execution. The vulnerability involves
changing the default set-max-intset-entries configuration value, creating a
large set key that consists of integer values and using the COPY command to
duplicate it. The integer overflow bug exists in all versions of Redis starting
with 2.6, where it could result with a corrupted RDB or DUMP payload, but not
exploited through COPY (which did not exist before 6.2).

Bug fixes:
* Cluster: Skip unnecessary check which may prevent failure detection (#8585)
* Fix not starting on alpine/libmusl without IPv6 (#8655)

Improvements:
* Fix performance regression in BRPOP on Redis 6.0 (#8689)

Modules:
* Fix edge-case when a module client is unblocked (#8618)

================================================================================
Redis 6.0.12     Released Mon Mar  1 17:29:52 IST 2021
================================================================================

Upgrade urgency: LOW, fixes a compilation issue.

Bug fixes:
* Fix compilation error on non-glibc systems if jemalloc is not used (#8533)

================================================================================
Redis 6.0.11     Released Mon Feb 22 16:13:23 IST 2021
================================================================================

Upgrade urgency: SECURITY if you use 32bit build of redis (see bellow), LOW
otherwise.

Integer overflow on 32-bit systems (CVE-2021-21309):
Redis 4.0 or newer uses a configurable limit for the maximum supported bulk
input size. By default, it is 512MB which is a safe value for all platforms.
If the limit is significantly increased, receiving a large request from a client
may trigger several integer overflow scenarios, which would result with buffer
overflow and heap corruption.

Bug fixes:
* Avoid 32-bit overflows when proto-max-bulk-len is set high (#8522)
* Fix handling of threaded IO and CLIENT PAUSE (failover), could lead to data loss or a crash (#8520)
* Fix the selection of a random element from large hash tables (#8133)
* Fix broken protocol in client tracking tracking-redir-broken message (#8456)
* XINFO able to access expired keys on a replica (#8436)
* Fix broken protocol in redis-benchmark when used with -a or --dbnum (#8486)
* Avoid assertions (on older kernels) when testing arm64 CoW bug (#8405)
* CONFIG REWRITE should honor umask settings (#8371)
* Fix firstkey,lastkey,step in COMMAND command for some commands (#8367)

Modules:
* RM_ZsetRem: Delete key if empty, the bug could leave empty zset keys (#8453)

================================================================================
Redis 6.0.10     Released Tue Jan 12 16:20:20 IST 2021
================================================================================

Upgrade urgency MODERATE: several bugs with moderate impact are fixed,
Here is a comprehensive list of changes in this release compared to 6.0.9.

Command behavior changes:
* SWAPDB invalidates WATCHed keys (#8239)
* SORT command behaves differently when used on a writable replica (#8283)
* EXISTS should not alter LRU (#8016)
  In Redis 5.0 and 6.0 it would have touched the LRU/LFU of the key.
* OBJECT should not reveal logically expired keys (#8016)
  Will now behave the same TYPE or any other non-DEBUG command.
* GEORADIUS[BYMEMBER] can fail with -OOM if Redis is over the memory limit (#8107)

Other behavior changes:
* Sentinel: Fix missing updates to the config file after SENTINEL SET command (#8229)
* CONFIG REWRITE is atomic and safer, but requires write access to the config file's folder (#7824, #8051)
  This change was already present in 6.0.9, but was missing from the release notes.

Bug fixes with compatibility implications (bugs introduced in Redis 6.0):
* Fix RDB CRC64 checksum on big-endian systems (#8270)
  If you're using big-endian please consider the compatibility implications with
  RESTORE, replication and persistence.
* Fix wrong order of key/value in Lua's map response (#8266)
  If your scripts use redis.setresp() or return a map (new in Redis 6.0), please
  consider the implications.

Bug fixes:
* Fix an issue where a forked process deletes the parent's pidfile (#8231)
* Fix crashes when enabling io-threads-do-reads (#8230)
* Fix a crash in redis-cli after executing cluster backup (#8267)
* Handle output buffer limits for module blocked clients (#8141)
  Could result in a module sending reply to a blocked client to go beyond the limit.
* Fix setproctitle related crashes. (#8150, #8088)
  Caused various crashes on startup, mainly on Apple M1 chips or under instrumentation.
* Backup/restore cluster mode keys to slots map for repl-diskless-load=swapdb (#8108)
  In cluster mode with repl-diskless-load, when loading failed, slot map wouldn't
  have been restored.
* Fix oom-score-adj-values range, and bug when used in config file (#8046)
  Enabling setting this in the config file in a line after enabling it, would
  have been buggy.
* Reset average ttl when empty databases (#8106)
  Just causing misleading metric in INFO
* Disable rehash when Redis has child process (#8007)
  This could have caused excessive CoW during BGSAVE, replication or AOFRW.
* Further improved ACL algorithm for picking categories (#7966)
  Output of ACL GETUSER is now more similar to the one provided by ACL SETUSER.
* Fix bug with module GIL being released prematurely (#8061)
  Could in theory (and rarely) cause multi-threaded modules to corrupt memory.
* Reduce effect of client tracking causing feedback loop in key eviction (#8100)
* Fix cluster access to unaligned memory (SIGBUS on old ARM) (#7958)
* Fix saving of strings larger than 2GB into RDB files (#8306)

Additional improvements:
* Avoid wasteful transient memory allocation in certain cases (#8286, #5954)

Platform / toolchain support related improvements:
* Fix crash log registers output on ARM. (#8020)
* Add a check for an ARM64 Linux kernel bug (#8224)
  Due to the potential severity of this issue, Redis will print log warning on startup.
* Raspberry build fix. (#8095)

New configuration options:
* oom-score-adj-values config can now take absolute values (besides relative ones) (#8046)

Module related fixes:
* Moved RMAPI_FUNC_SUPPORTED so that it's usable (#8037)
* Improve timer accuracy (#7987)
* Allow '\0' inside of result of RM_CreateStringPrintf (#6260)

================================================================================
Redis 6.0.7     Released Fri Aug 28 11:05:09 IDT 2020
================================================================================

Upgrade urgency MODERATE: several bugs with moderate impact are fixed,
Specifically the first two listed below which cause protocol errors for clients.

Bug fixes:

* CONFIG SET could hung the client when arrives during RDB/ROF loading (When
  processed after another command that was also rejected with -LOADING error)
* LPOS command when RANK is greater than matches responded wiht broken protocol
  (negative multi-bulk count)
* UNLINK / Lazyfree for stream type key would have never do async freeing
* PERSIST should invalidate WATCH (Like EXPIRE does)
* EXEC with only read commands could have be rejected when OOM
* TLS: relax verification on CONFIG SET (Don't error if some configs are set
  and tls isn't enabled)
* TLS: support cluster/replication without tls-port
* Systemd startup after network is online
* Redis-benchmark improvements
* Various small bug fixes

New features:

* Add oom-score-adj configuration option to control Linux OOM killer
* Show IO threads statistics and status in INFO output
* Add optional tls verification mode (see tls-auth-clients)

Module API:

* Add RedisModule_HoldString
* Add loaded keyspace event
* Fix RedisModuleEvent_LoadingProgress
* Fix RedisModuleEvent_MasterLinkChange hook missing on successful psync
* Fix missing RM_CLIENTINFO_FLAG_SSL
* Refactor redismodule.h for use with -fno-common / extern

================================================================================
Redis 6.0.6     Released Mon Jul 20 09:31:30 IDT 2020
================================================================================

Upgrade urgency MODERATE: several bugs with moderate impact are fixed here.

The most important issues are listed here:

* Fix crash when enabling CLIENT TRACKING with prefix
* EXEC always fails with EXECABORT and multi-state is cleared
* RESTORE ABSTTL won't store expired keys into the db
* redis-cli better handling of non-pritable key names
* TLS: Ignore client cert when tls-auth-clients off
* Tracking: fix invalidation message on flush
* Notify systemd on Sentinel startup
* Fix crash on a misuse of STRALGO
* Few fixes in module API
* Fix a few rare leaks (STRALGO error misuse, Sentinel)
* Fix a possible invalid access in defrag of scripts (unlikely to cause real harm)

New features:

* LPOS command to search in a list
* Use user+pass for MIGRATE in redis-cli and redis-benchmark in cluster mode
* redis-cli support TLS for --pipe, --rdb and --replica options
* TLS: Session caching configuration support

Redis 6.0.5     Released Tue Jun 09 11:56:08 CEST 2020
================================================================================

Upgrade urgency MODERATE: several bugs with moderate impact are fixed here.

The most important issues are listed here:

* Fix handling of speical chars in ACL LOAD.
* Make Redis Cluster more robust about operation errors that may lead
  to two clusters to mix together.
* Revert the sendfile() implementation of RDB transfer. It causes some delay.
* Fix TLS certificate loading for chained certificates.
* Fix AOF rewirting of KEEPTTL SET option.
* Fix MULTI/EXEC behavior during -BUSY script errors.

================================================================================
Redis 6.0.4     Released Thu May 28 11:36:45 CEST 2020
================================================================================

Upgrade urgency CRITICAL: this release fixes a severe replication bug.

Redis 6.0.4 fixes a critical replication bug caused by a new feature introduced
in Redis 6. The feature, called "meaningful offset" and strongly wanted by
myself (antirez) was an improvement that avoided that masters were no longer
able, during a failover where they were demoted to replicas, to partially
synchronize with the new master. In short the feature was able to avoid full
synchronizations with RDB. How did it work? By trimming the replication backlog
of the final "PING" commands the master was sending in the replication channel:
this way the replication offset would no longer go "after" the one of the
promoted replica, allowing the master to just continue in the same replication
history, receiving only a small data difference.

However after the introduction of the feature we (the Redis core team) quickly
understood there was something wrong: the apparently harmless feature had
many bugs, and the last bug we discovered, after a joined effort of multiple
people, we were not even able to fully understand after fixing it. Enough was
enough, we decided that the complexity cost of this feature was too high.
So Redis 6.0.4 removes the feature entirely, and fixes the data corruption that
it was able to cause.

However there are two facts to take in mind.

Fact 1: Setups using chained replication, that means that certain replicas
are replicating from other replicas, up to Redis 6.0.3 can experience data
corruption. For chained replication we mean that:

    +--------+          +---------+         +-------------+
    | master |--------->| replica |-------->| sub-replica |
    +--------+          +---------+         +-------------+


People using chained replication SHOULD UPGRADE ASAP away from Redis 6.0.0,
6.0.1, 6.0.2 or 6.0.3 to Redis 6.0.4.

To be clear, people NOT using this setup, but having just replicas attached
directly to the master, SHOUDL NOT BE in danger of any problem. But we
are no longer confident on 6.0.x replication implementation complexities
so we suggest to upgrade to 6.0.4 to everybody using an older 6.0.3 release.
We just so far didn't find any bug that affects Redis 6.0.3 that does not
involve chained replication.

People starting with Redis 6.0.4 are fine. People with Redis 5 are fine.
People upgrading from Redis 5 to Redis 6.0.4 are fine.
TLDR: The problem is with users of 6.0.0, 6.0.1, 6.0.2, 6.0.3.

Fact 2: Upgrading from Redis 6.0.x to Redis 6.0.4, IF AND ONLY IF you
use chained replication, requires some extra care:

1. Once you attach your new Redis 6.0.4 instance as a replica of the current
   Redis 6.0.x master, you should wait for the first full synchronization,
   then you should promote it right away, if your setup involves chained
   replication. Don't give it the time to do a new partial synchronization
   in the case the link between the master and the replica  will break in
   the mean time.

2. As an additional care, you may want to set the replication ping period
   to a very large value (for instance 1000000) using the following command:

       CONFIG SET repl-ping-replica-period 1000000

   Note that if you do "1" with care, "2" is not needed.
   However if you do it, make sure to later restore it to its default:

       CONFIG SET repl-ping-replica-period 10

So this is the main change in Redis 6. Later we'll find a different way in
order to achieve what we wanted to achieve with the Meaningful Offset feature,
but without the same complexity.

Other changes in this release:

* PSYNC2 tests improved.
* Fix a rare active defrag edge case bug leading to stagnation
* Fix Redis 6 asserting at startup in 32 bit systems.
* Redis 6 32 bit is now added back to our testing environments.
* Fix server crash for STRALGO command,
* Implement sendfile for RDB transfer.
* TLS fixes.
* Make replication more resistant by disconnecting the master if we
  detect a protocol error. Basically we no longer accept inline protocol
  from the master.
* Other improvements in the tests.

antirez

================================================================================
Redis 6.0.2     Released Fri May 15 22:24:36 CEST 2020
================================================================================

Upgrade urgency MODERATE: many not critical bugfixes in different areas.
                          Critical fix to client side caching when
                          keys are evicted from the tracking table but
                          no notifications are sent.

The following are the most serious fix:

* XPENDING should not update consumer's seen-time
* optimize memory usage of deferred replies - fixed
* Fix CRC64 initialization outside the Redis server itself.
* stringmatchlen() should not expect null terminated strings.
* Cluster nodes availability checks improved when there is
  high Pub/Sub load on the cluster bus.
* Redis Benchmark: Fix coredump because of double free
* Tracking: send eviction messages when evicting entries.
* rax.c updated from upstream antirez/rax.
* fix redis 6.0 not freeing closed connections during loading.

New features:

* Support setcpuaffinity on linux/bsd
* Client Side Caching: Add Tracking Prefix Number Stats in Server Info
* Add --user argument to redis-benchmark.c (ACL)

Redis 6.0.1     Released Sat May 02 00:06:07 CEST 2020
================================================================================

Upgrade urgency HIGH: This release fixes a crash when builiding against
                      Libc malloc.

Here we revert 8110ba888, an optimization that causes a crash due to a
bug in the code. It does not happen with the default allocator because of
differences between Jemalloc and libc malloc, so this escaped all our
testing but was reported by a user. We'll add back the original optimization
that was reverted here later, after checking what happens: it is not a
critical optimization.

Redis 6.0.0 GA  Released Thu Apr 30 14:55:02 CEST 2020
================================================================================

Upgrade urgency CRITICAL: many bugs fixed compared to the last release
                          candidate. Better to upgrade if you see things
                          affecting your environment in the changelog.

Hi all, finally we have Redis 6.0.0 GA! Enjoy this new Redis release.
Most of the documentation was updated today so that you can likely
find what you are looking for about the new features at redis.io.
This is the list of what changed compared to the previoius release candidate:

* XCLAIM AOF/replicas propagation fixed.
* Client side caching: new NOLOOP option to avoid getting notified about
  changes performed by ourselves.
* ACL GENPASS now uses HMAC-SHA256 and have an optional "bits" argument.
  It means you can use it as a general purpose "secure random strings"
  primitive!
* Cluster "SLOTS" subcommand memory optimization.
* The LCS command is now a subcommand of STRALGO.
* Meaningful offset for replicas as well. More successful partial
  resynchronizations.
* Optimize memory usage of deferred replies.
* Faster CRC64 algorithm for faster RDB loading.
* XINFO STREAM FULL, a new subcommand to get the whole stream state.
* CLIENT KILL USER <username>.
* MIGRATE AUTH2 option, for ACL style authentication support.
* Other random bugfixes.

Enjoy Redis 6! :-)

================================================================================
Redis 6.0-rc4     Released Thu Apr 16 16:10:35 CEST 2020
================================================================================

Upgrade urgency LOW: If you are using RC3 without issues, don't rush.

Hi all, this the latest release candidate of Redis 6. This is likely to
be very similar to what you'll see in Redis 6 GA. Please test it and
report any issue :-)

Main changes in this release:

    * Big INFO speedup when using a lot of of clients.
    * Big speedup on all the blocking commands: now blocking
      on the same key is O(1) instead of being O(N).
    * Stale replicas now allow MULTI/EXEC.
    * New command: LCS (Longest Common Subsequence).
    * Add a new configuration to make DEL like UNLINK.
    * RDB loading speedup.
    * Many bugs fixed (see the commit messages at the end of this node)

See you in 14 days for Redis 6 GA.

================================================================================
Redis 6.0-rc3     Released Tue Mar 31 17:42:39 CEST 2020
================================================================================

Upgrade urgency CRITICAL: A connection management bug introduced with the
                          SSL implementation can crash Redis easily.

Dear users, this is a list of the major changes in this release, please check 
the list of commits for detail:

* Fix crash due to refactoring for SSL, for the connection code.
* Precise timeouts for blocking commands. Now the timeouts have HZ
  resolution regardless of the number of connected clinets. New timeouts
  are stored in a radix tree and sorted by expire time.
* Fix rare crash when resizing the event loop because of CONFIG maxclients.
* Fix systemd readiness after successful partial resync.
* Redis-cli ask password mode to be prompted at startup (for additional safety).
* Keyspace notifications added to MIGRATE / RESTORE.
* Threaded I/O bugs fixed.
* Implement new ACL style AUTH in Sentinel.
* Make 'requirepass' more backward compatible with Redis <= 5.
* ACL: Handle default user as disabled if it's off regardless of "nopass".
* Fix a potential inconsistency when upgrading an instance in Redis Cluster
  and restarting it. The instance will act as a replica but will actually be
  set as a master immediately. However the choice of what to do with already
  expired keys, on loading, was made from the POV of replicas.
* Abort transactions after -READONLY error.
* Many different fixes to module APIs.
* BITFIELD_RO added to call the command on read only replicas.
* PSYNC2: meaningful offset implementation. Allow the disconnected master
  that is still sending PINGs to replicas, to be able to successfully
  PSYNC incrementally to new slaves, discarding the last part of the
  replication backlog consisting only of PINGs.
* Fix pipelined MULTI/EXEC during Lua scripts are in BUSY state.
* Re-fix propagation API in modules, broken again after other changes.

================================================================================
Redis 6.0 RC2     Released Thu Mar 05 15:40:53 CET 2020
================================================================================

Upgrade urgency MODERATE: Normal bugfixing release of a non-GA branch.

Hi Redis users, Redis 6 is approaching and will be released 30th of April.
New release candidates will be released at the end of March, then another
one mid April, to finally reach the GA at the end of April.

Redis 6 RC2 brings many fixes and new things, especially in the area of
client side caching. This is the list of big changes in this release. As
usually you can find the full list of commits at the end:

New features and improvements:

* ACL LOG: log denied commands, keys accesses and authentications.
* Client side caching redesigned. Now we use keys not caching slots.
* Client side caching: Broadcasting mode implemented.
* Client side caching: OPTIN/OPTOUT modes implemented.
* Remove RDB files used for replication in persistence-less instances (option).

Fixes (only selected ones, see commits for all the fixes):

* Different fixes to streams in edge cases.
* Fix duplicated CLIENT SETNAME reply because of RESP3 changes.
* Fix crash due to new active expire division by zero.
* Avoid sentinel changes promoted_slave to be its own replica.
* Fix bug on KEYS command where pattern starts with * followed by \x00.
* Threaded I/O: now the main thread is used as well to do I/O.
* Many fixes to modules APIs, and more to come in the next RCs.
* ld2string should fail if string contains \0 in the middle.
* Make the Redis test more reliable.
* Fix SPOP returning nil (see #4709). WARNING: API change.

================================================================================
Redis 6.0 RC1   Released Thu Dec 19 09:58:24 CEST 2019
================================================================================

Upgrade urgency LOW: This is the first RC of Redis 6.

Introduction to the Redis 6 release
===================================

Redis 6 improves Redis in a number of key areas and is one of the largest
Redis releases in the history of the project, so here we'll list only
the biggest features in this release:

* The modules system now has a number of new APIs that allow module authors
  to make things otherwise not possible in the past. It is possible to
  store arbitrary module private data in RDB files, to hook on different
  server events, capture and rewrite commands executions, block clients on
  keys, and so forth. 
* The Redis active expire cycle was rewritten for much faster eviction of keys
  that are already expired. Now the effort is tunable.
* Redis now supports SSL on all channels.
* ACL support, you can define users that can run only certain commands and/or
  can only access only certain keys patterns.
* Redis now supports a new protocol called RESP3, which returns more
  semantical replies: new clients using this protocol can understand just
  from the reply what type to return to the calling program.
* There is server-side support for client-side caching of key values. This
  feature is still experimental and will get more changes during the next
  release candidates, but you can already test it and read about it here:
  https://redis.io/topics/client-side-caching
* Redis can now optionally use threads to handle I/O, allowing to serve
  2 times as much operations per second in a single instance when
  pipelining cannot be used.
* Diskless replication is now supported even on replicas: a replica is now
  able, under certain conditions the user can configure, to load the RDB
  in the first synchronization directly from the socket to the memory.
* Redis-benchmark now supports a Redis Cluster mode.
* SRANDMEMBER and similar commands have a better distribution.
* Redis-cli improvements.
* Systemd support rewritten.
* A Redis Cluster proxy was released here:
  https://github.com/artix75/redis-cluster-proxy
* A Disque module for Redis was released here:
  https://github.com/antirez/disque-module

Thanks to all the users and developers who made this release possible.
We'll follow up with more RC releases, until the code looks production ready
and we don't get reports of serious issues for a while.

A special thank you for the amount of work put into this release
(in decreasing number of commits, only listing contributors with more
than a single commit) by:

Migrating from 5.0 to 6.0
=========================

Redis 6.0 is mostly a strict superset of 5.0, you should not have any problem
upgrading your application from 5.0 to 6.0. However this is a list of small
non-backward compatible changes introduced in the 6.0 release:

* The SPOP <count> command no longer returns null when the set key does not
  exist. Now it returns the empty set as it should and as happens when it is
  called with a 0 argument. This is technically a fix, however it changes the
  old behavior.

--------------------------------------------------------------------------------

Credits: For each release, a list of changes with the relative author is
provided. Where not specified the implementation and design is done by
Salvatore Sanfilippo. Thanks to Redis Labs for making all this possible.
Also many thanks to all the other contributors and the amazing community
we have.

Commit messages may contain additional credits.

Enjoy,
Salvatore
