Hello! This file is just a placeholder, since this is the "unstable" branch Redis 5.0 release notes
of Redis, the place where all the development happens. =======================
There is no release notes for this branch, it gets forked into another branch --------------------------------------------------------------------------------
every time there is a partial feature freeze in order to eventually create Upgrade urgency levels:
a new stable release.
Usually "unstable" is stable enough for you to use it in development environments LOW: No need to upgrade unless there are new features you want to use.
however you should never use it in production environments. It is possible MODERATE: Program an upgrade of the server, but it's not urgent.
to download the latest stable release here: HIGH: There is a critical bug that may affect a subset of users. Upgrade!
CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP.
SECURITY: There are security fixes in the release.

================================================================================
More information is available at http://redis.io Upgrade urgency LOW: This is the first RC of Redis 5.
Happy hacking! Introduction to the Redis 5 release
===================================
Redis 5 is a release focused on a few important features. While Redis 4
was very very focused on operations, Redis 5 changes are mostly user-facing,
with the implementation of new data types and operations on top of existing
types. The following are the major features of this release:
1. The new Stream data type. https://redis.io/topics/streams-intro
2. New Redis modules APIs: Timers and Cluster API.
3. RDB now store LFU and LRU information.
4. The cluster manager was ported from Ruby (redis-trib.rb) to C code
inside redis-cli. Check `redis-cli --cluster help` for more info.
5. New sorted set commands: ZPOPMIN/MAX and blocking variants.
6. Active defragmentation version 2.
7. Improvemenets in HyperLogLog implementations.
8. Better memory reporting capabilities.
9. Many commands with sub-commands now have an HELP subcommand.
10. Better performances when clients connect and disconnect often.
11. Many bug fixes and other random improvements.
12. Jemalloc was upgraded to version 5.1
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.

Migrating from 4.0 to 5.0
=========================
Redis 4.0 is mostly a strict subset of 5.0, you should not have any problem
upgrading your application from 4.0 to 5.0. However this is a list of small
non-backward compatible changes introduced in the 5.0 release:
* redis-cli now implements the cluster management tool. We still ship the
old redis-trib, but new fixes will be implemented only in redis-cli.
See `redis-cli --cluster help` for more info.
* The RDB format changed. Redis 5.0 is still able to read 4.0 (and all the
past versions) files, but not the other way around.
* Certain log formats and sentences are different in Redis 5.0.
--------------------------------------------------------------------------------
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
