Redis 7.2 RC1 Released Wed Mar 22 12:00:00 IST 2023
================================================================================
Upgrade urgency LOW: This is the first Release Candidate for Redis 7.2.
Redis Release Candidate (RC) versions are early versions that are made available
for early adopters in the community to test them. We do not consider
them suitable for production environments.
Introduction to the Redis 7.2 release
=====================================
Redis 7.2 includes optimizations, several new commands, some improvements,
bug fixes, and several new module APIs.
In particular, users should be aware of the following changes:
1. Redis 7.2 uses a new format (version 11) for RDB files, which is incompatible
with older versions.
2. See section about breaking changes mentioned below.
3. If you use modules, see the module API breaking changes section below.
Here is a comprehensive list of changes in this release compared to 7.0.10.
Each one includes the PR number that added it so that you can get more details
at https://github.com/redis/redis/pull/<number>
New Features
============
* Introduce WAITAOF command, to block the client until a specified number
of Redises have synced all previous write commands to the AOF on disk,
see https://redis.io/commands/waitaof/
New user commands or command arguments
--------------------------------------
* WAITAOF blocks until writes have been synced to disk (#11713)
* Add WITHSCORE option to ZRANK and ZREVRANK (#11235)
New administrative and introspection commands and command arguments
-------------------------------------------------------------------
* CLIENT SETINFO lets client library report name and version Redis (#11758)
* CLIENT NO-TOUCH for clients to run commands without affecting LRU/LFU of keys (#11483)
Command replies that have been extended
---------------------------------------
* ACL LOG - Add entry id, timestamp created, and timestamp last updated time (#11477)
* COMMAND DOCS - Repurpose arg names as the unique ID (#11051)
* CLIENT LIST has `T` flag to indicate CLIENT NO-TOUCH (#11483)
* CLIENT LIST show lib-name, lib-ver (#11758)
Potentially Breaking / Behavior Changes
=======================================
* Client side tracking for scripts now tracks the keys that are read by the
script instead of the keys that are declared by the caller of EVAL / FCALL (#11770)
* Freeze time sampling during command execution and in scripts (#10300)
* When a blocked command is being unblocked, checks like ACL, OOM, etc are
re-evaluated (#11012)
* Unify ACL failure error message text and error codes (#11160)
* Blocked stream command that's released when key no longer exists carries a
different error code (#11012)
* Command stats are updated for blocked commands only when / if the command
actually executes (#11012)
* The way ACL users are stored internally no longer removes redundant command
and category rules, which may alter the way those rules are displayed as part
of `ACL SAVE`, `ACL GETUSER` and `ACL LIST` (#11224)
* Client connections created for TLS-based replication use SNI if possible (#11458)
* Stream consumers: Re-purpose seen-time, add active-time (#11099)
* XREADGROUP and X[AUTO]CLAIM create the consumer regardless of whether it was
able to perform some reading/claiming (#11099)
* ACL default newly created user set sanitize-payload flag in ACL LIST/GETUSER #11279
* Fix HELLO command not to affect the client state unless successful (#11659)
* Normalize `NAN` in replies to a single nan type, like we do with `inf` (#11597)
Deprecations
============

* Delete RDB loading code for pre-release RDB formats (#11058)
Performance and resource utilization improvements

* Significant memory optimization for small set type keys (#11290)
* Significant memory optimization for large sets (#11595)
* Significant speed optimization in ZRANGE replies WITHSCORES in case of integer scores (#11779)
* Significant speed optimization in double replies, mainly sorted sets commands (#10587)
* Optimize the performance of commands with multiple keys in cluster mode (#11044)
* Incrementally reclaim OS page cache of RDB file (#11248)
* Improve memory management of cluster bus links when there is a large number of pending messages (#11343)
* Minor performance improvement for workloads that use commands without pipelining (#11220)
Changes in CLI tools
====================
* redis-cli accepts commands in subscribed mode (#11873)
Other General Improvements
==========================
* WAIT now no longer waits for the replication offset after your last command,
but rather the replication offset after your last write (#11713)
* Automatically propagate node deletion to other nodes in a cluster when
`CLUSTER FORGET` is called, allowing nodes to be deleted with a single call
in most cases (#10869)
* Blocking commands that were disallowed in scripts now behave in scripts the
same they did in MULTI (#11568)
Platform / toolchain support related changes
=================================================

will consume more memory (#11595)

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.
