+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 ANY argument to GEOSEARCH and GEORADIUS (#8259)
+* Add the CH, NX, XX arguments to GEOADD (#8227)
+* Add the COUNT argument to LPOP and RPOP (#8179)
+* Add the WRITE argument to CLIENT PAUSE for pausing write commands exclusively (#8170)
+* 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)
+* Remove the read-only flag from TIME, ECHO, ROLE, LASTSAVE (#8216)
+* Fix the command flags of PFDEBUG (#8222)
+* Tracking clients will no longer receive unnecessary key invalidation messages after FLUSHDB (#8039)
+* 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 redis-benchmark to use an IP address for the first cluster node (#8154)
+* 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)
+* Add the failed_calls and rejected_calls fields INFO's commandstats section (#8217)
+* Report child copy-on-write metrics continuously (#8264)
+
+Module API changes:
+* Add the RedisModule_SendChildCOWInfo API (#8264)
+* Add the may-replicate command flag (#8170)
