[RELEASE] Redis 6.0.10 is out

[re...@redis.io]

Hi all,

Redis 6.0.10 is out. This is a maintenance release - please see the full
release notes below.

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)

Cheers,
The Redis team
