Redis 6.2 RC2 Released Tue Jan 12 16:17:20 IST 2021
|
||||
================================================================================
|
||||
|
||||
Upgrade urgency LOW: This is the second Release Candidate of Redis 6.2.
|
||||
|
||||
IMPORTANT: If you're running Redis on ARM64 or a big-endian system, upgrade may
|
||||
have significant implications. Please be sure to read the notes below.
|
||||
|
||||
Here is a comprehensive list of changes in this release compared to 6.2 RC1,
|
||||
each one includes the PR number that added it, so you can get more details
|
||||
at https://github.com/redis/redis/pull/<number>
|
||||
|
||||
New commands / args:
|
||||
* Add the REV, BYLEX and BYSCORE arguments to ZRANGE, and the ZRANGESTORE command (#7844)
|
||||
* Add the XAUTOCLAIM command (#7973)
|
||||
* Add the MINID trimming strategy and the LIMIT argument to XADD and XTRIM (#8169)

|
||||
* Add the CH, NX, XX arguments to GEOADD (#8227)
|
||||
* Add the COUNT argument to LPOP and RPOP (#8179)
|
||||

|
||||
* Change the proto-ver argument of HELLO to optional (#7377)
|
||||
* Add the CLIENT TRACKINGINFO subcommand (#7309)
|
||||
|
||||
Command behavior changes:
|
||||
* CLIENT TRACKING yields an error when given overlapping BCAST prefixes (#8176)
|
||||
* SWAPDB invalidates WATCHed keys (#8239)
|
||||
* SORT command behaves differently when used on a writable replica (#8283)
|
||||
|
||||
Other behavior changes:
|
||||
* Avoid propagating MULTI/EXEC for read-only transactions (#8216)
|
||||

|
||||

|
||||
* Sentinel: Fix missing updates to the config file after SENTINEL SET command (#8229)
|
||||
|
||||
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 that are only applicable to previous releases of Redis 6.2:
|
||||
* Resolve rare assertions in active defragmentation while loading (#8284, #8281)
|
||||
|
||||
Bug fixes:
|
||||
* Fix the selection of a random element from large hash tables (#8133)
|
||||
* 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)
|
||||

|
||||
* Fix saving of strings larger than 2GB into RDB files (#8306)
|
||||
|
||||
Additional improvements:
|
||||
* Improve replication handshake time (#8214)
|
||||
* Release client tracking table memory asynchronously in cases where the DB is also freed asynchronously (#8039)
|
||||
* Avoid wasteful transient memory allocation in certain cases (#8286, #5954)
|
||||
* Handle binary string values by the 'requirepass' and 'masterauth' configs (#8200)
|
||||
|
||||
Platform and deployment-related changes:
|
||||
* Install redis-check-rdb and redis-check-aof as symlinks to redis-server (#5745)
|
||||
* Add a check for an ARM64 Linux kernel bug (#8224)
|
||||
Due to the potential severity of this issue, Redis will refuse to run on
|
||||
affected platforms by default.
|
||||
|
||||
Info fields and introspection changes:
|
||||
* Add the errorstats section to the INFO command (#8217)
