Redis 4.0 release notes
=======================
--------------------------------------------------------------------------------
Upgrade urgency levels:
LOW: No need to upgrade unless there are new features you want to use.
MODERATE: Program an upgrade of the server, but it's not urgent.
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.
--------------------------------------------------------------------------------
================================================================================
Redis 4.0.1 Released Mon Jul 24 15:51:31 CEST 2017
================================================================================
Upgrade urgency MODERATE: A few serious but non critical bugs in the modules
subsystem. A rare Redis Cluster crash fixed.
Many other minor fixes.
Hi everybody. This is the first patch level release of Redis 4.0, fixing the
obvious last minute issues discovered just after the 4.0.0 GA release, plus
a few other things that were no-brainers. The highlights here in terms
of bug fixing are:
1. Loading two or more modules exporting native data types resulted into the
inability to reload the RDB file.
2. Crash in modules when calling from Lua scripts module commands that would
block.
3. A Redis Cluster crash due to mis-handling of the "migrate-to" internal
flag.
4. Other smaller fixes not worth of a release per se, but nice to add here.
If you upgraded to 4.0 to use modules, definitely a required upgrade.
If you are using Redis Cluster, also a good idea to upgrade.
Otherwise... You can definitely wait for the next one :-)
Cheers,
Salvatore

Redis 4.0.0 Released Fri Jul 14 13:04:44 CEST 2017
================================================================================
Upgrade urgency CRITICAL: 4.0.0 GA fixes many important bugs.
Dear Redis users,
this is the first stable version of Redis 4.0. There are a number
of bug fixes and improvements compared to the previous RC, mainly:
* Different replication fixes to PSYNC2, the new 4.0 replication engine.
* Modules thread safe contexts were introduced. They are an experimental API right now, but the API is considered to be stable and usable when needed.
* SLOWLOG now logs the offending client name and address. Note that this is a backward compatibility breakage in case old code assumes that the slowlog entry is composed of exactly three entries.
* The modules native data types RDB format changed.
* The AOF check utility is now able to deal with RDB preambles.
* GEORADIUS_RO and GEORADIUSBYMEMBER_RO variants, not supporting the STORE option, were added in order to allow read-only scaling of such queries.
* HSET is now variadic, and HMSET is considered deprecated (but will be supported for years to come). Please use HSET in new code.
* GEORADIUS huge radius (>= ~6000 km) corner cases fixed, certain elements near the edges were not returned.
* DEBUG DIGEST modules API added.
* HyperLogLog commands no longer crash on certain input (non HLL) strings.
* Fixed SLAVEOF inside MULTI/EXEC blocks.
* Many other minor bug fixes and improvements.
Note that 4.0 is probably one of the most extreme releases of Redis ever
made in terms of changes inside the internals: all the aggregated data types
no longer use Redis Objects structures but directly SDS objects, certain
deletion operations are now threaded, the replication engine was modified
in many ways. So please handle this release with care. A few patch-level
releases will follow in the next weeks and months fixing the important issues
discovered by the users.
You can read the new set of features below in this file, there are a lot
of improvements that can make a real difference in real world use cases.
Also note that Redis 4.0 is, as usually, almost a perfect superset of Redis
3.2, so it is very rare that compatibility with the past is broken in terms
of exported commands.
IMPORTANT: Redis Cluster users, please note that, as specified in the list
of incompatibilities, Redis 4.0 cluster bus protocol is not compatible with
Redis 3.2, so in order to upgrade, a mass reboot of the instances is needed
and rolling upgrades are not possible. This change was needed in order to
add compatibility for Containers/NAT, where the bus port at a fixed offset
was not an acceptable design, so we had to change many things, resulting
in the incompatible protocol.
Have fun with Redis 4.0!

================================================================================
Redis 4.0-RC3 Released Sat Apr 22 11:19:56 CEST 2017
================================================================================
Upgrade urgency HIGH: Many bugs fixed and many improvements operated, so who
is using 4.0 RC2 should upgrade if possible, or at least
should carefully read this release notes to understand if
it may be affected by some bug.
Redis 3.9.103 (4.0 RC3 for the friends) is finally out, and the list of commits
is pretty long, so here is a synopsis of all the major changes operated in this
release.
Major things:
* Finally the infamous leakage of keys with an expire, in slaves that are
configured as writable, is fixed. (Salvatore Sanfilippo)
* A serious MIGRATE issue forgetting to store the TTL of the key under
certain conditions is fixed. (reported by Jinbei Wang, fixed by Jan-Erik
Rediger).
* An in-depth investigation of the ziplist implementation was performed.
The final result was:
1. An in depth auditing (Salvatore Sanfilippo and Oran Agra).
2. The discovery of a bug and its fix (Salvatore Sanfilippo).
3. The creation of a new specification to replace ziplists with something
better, listpacks: https://gist.github.com/antirez/66ffab20190ece8a7485bd9accfbc175 (Yuval Inbar, Salvatore Sanfilippo, Oran Agra).
4. Refactoring and function to dump a ziplist for debugging purposes
(Salvatore Sanfilippo).
* New major feature: Memory de-fragmentation. This feature, contributed by
Oran Agra, allows Redis to perform "online defragmentation" of memory
if the Jemalloc allocator is used. There is some documentation in the
example `redis.conf` file. (Oran Agra)
* Support for ARM. (Salvatore Sanfilippo)
* Fix a very important "family of bugs" about PSYNC2, thanks to the help
of Kevin McGehee, Siran Yang and Oran Agra.
* Hash function moved to SipHash 1-2 variant. (Salvatore Sanfilippo)
* Redis Cluster failure detection improved in different ways, the most
important result is to exchange a lot less messages among nodes. (Salvatore
Sanfilippo)
All the rest:
* A bug in the modules API ziplist iterator was fixed. (Dvir Volk).
* The HyperLogLog implementation final cardinality approximation function
was improved to use the LogLog-Beta algorithm. (Harish Murthy and
Salvatore Sanfilippo).
* Edge case copy-on-write disaster fix (Oran Agra).
* Now the Redis ASCII art logo is shown only if logging to stdout and if the
stdout is a tty. (Salvatore Sanfilippo because of users request).
* A new GEO bug fixed (and there is another pending when huge radiuses are
used, where elements at the edge may be miss-reported). (Salvatore
Sanfilippo). ***IMPORTANT*** See the list of incompatibilities below
since the GEO API has some potentially backward incompatible change.
* ZADD crash on syntax error fixed. (Itamar Haber)
* Fixed a division by zero but in MEMORY DOCTOR. (Jan-Erik Rediger)
* More MIGRATE bugs fixed. (Salvatore Sanfilippo)
* Different file descriptors potential lakes fixed. (multiple authors)
* Support for Solaris improved. (Salvatore Sanfilippo)
* Improve memory reclaiming in freeMemoryIfNeeded(). (Oran Agra and
Salvatore Sanfilippo)
* Fixes multiple bugs in the test suite. (Salvatore Sanfilippo)
* Fix asynchronous commands in modules API. (Dvir Volk and Salvatore Sanfilippo)
* A new data structure, the radix tree (rax.c) was introduced into Redis in
order to fix a major Redis Cluster slowdown. (Salvatore Sanfilippo)
* Fix `lua-time-limit` config ignored in `redis.conf`. (Salvatore Sanfilippo)
* Jemalloc downgraded to an apparently safe version, given that recent
releases apparently hang under certain conditions. See Redis issue #3799.

many information is inside the full commit message, while here only the first

Redis 4.0.0-RC2 Released Tue Dec 06 09:25:35 CET 2016
================================================================================
Upgrade urgency LOW: This release mainly fixes a rare GEO API bug and a crash
related to the modules subsystem.
Redis 4.0.0-RC2 (version number 3.9.102) just fixes two bugs:
1. GEORADIUS could fail reporting items with very big radius lengths because
of a bug in the bounding box computation function. This was fixed and tests
with large radius sizes were added.
2. There was a crash in the modules subsystem that was not merged into RC1 for
an error, while it was already fixed into the "unstable" branch.
The list of commits follows:

Redis 4.0.0-RC1 Released Fri Dec 2 10:40:01 CEST 2016
================================================================================
Redis 4.0.0-RC1 (version number 3.9.101) is the first release candidate of
Redis 4.0. It is not a production quality release but all the major features
received some testing at this point, the release in feature freeze excluding
things that are considered in the middle ground between fixes and improvements.
Redis 4.0 is not called 3.4 because it is a major release that adds a number
of important and non trivial features. Many core functionalities of Redis were
seriously reworked. In the next release candidates, with your help, we'll gain
informations about the stability level of this release and will produce a new
RC every 2-4 weeks. When the entity and frequency of bug reports will slow down
under a certain level, Redis 4.0 final will be released.
As usually, certain changes to Cluster and Sentinel may not follow the Redis
release cycle and could be incorporated into Redis 4.0 at RC stage or even
after the final version, every time the changes are considered to benefit
the user base enough to be worth incorporating them ASAP without waiting
for Redis 4.2.
So, what's new in Redis 4.0?
Major features
---
* Redis modules system. Redis now allows developers to write modules that can extend the Redis functionalities and implement new data types. The module API implements a complete abstraction layer that separates the Redis core from the module implementation, allowing the same module to be loaded by different versions of Redis without modifications. See the modules documentation here for more info: https://github.com/antirez/redis/blob/unstable/src/modules/INTRO.md
* Partial Replication (PSYNC) version 2. The replication protocol was enhanced (in a backward compatible way, so that 4.0 can still act as a slave of older instances) in order to be able to partially resynchronize slaves and masters in conditions where it was impossible in the past: after a master switch because of a failover and when a slave instance is restared. Even masters turned into slaves will usually be able to partially resynchronize with the new master, if the new master was a former slave of the old master instance. The way the replication work for chained slaves (sub-slaves) is now very different, and each slave receives the same replication stream generated by the top-level master.
* Cache eviction improvements. Redis 4.0 implements LFU (Least Frequently Used) as a new eviction algorithm, and improves the functionality, performances and precision of the existing algorithms. This blog post contains info about the changes: http://antirez.com/news/109
* Lazy freeing of keys. Redis is now able to delete keys in the background in a different thread without blocking the server. The new `UNLINK` command is the same as `DEL` but working in a non blocking way. Similarly an `ASYNC` option was added to `FLUSHALL` and `FLUSHDB` in order to let the entire dataset or a single database to be freed asynchronously.
