Redis 5.0 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.
SECURITY: There are security fixes in the release.
--------------------------------------------------------------------------------
================================================================================
Redis 5.0.5 Released Wed May 15 17:57:41 CEST 2019
================================================================================
Upgrade urgency CRITICAL: This release fixes an important AOF fysnc bug
and other less critical issues.
Dear user,
Redis 5.0.5 fixes an important issue with AOF and adds multiple very useful
modules APIs. Moreover smaller bugs in other parts of Redis are fixed in
this release.
The AOF bug
-----------
The AOF bug happens when the fsync policy is set to "everysec", which is the
default: if the write load in the server drops immediately, the commands
executed in the latest second may not be fsync-ed to disk as it should.
This may lead to data loss in case the write load drops immediately and
successively a server crash happens.
Other things in this release
----------------------------
* Streams: a bug in the iterator could prevent certain items to be returned in
range queries under specific conditions.
* Memleak in bitfieldCommand fixed.
* Modules API: Preserve client->id for blocked clients.
* Fix memory leak when rewriting config file in case of write errors.
* New modules API: RedisModule_GetKeyNameFromIO().
* Fix non critical bugs in diskless replication.
* New mdouels API: command filtering. See RedisModule_RegisterCommandFilter();
* Tests improved to be more deterministic.
* Fix a Redis Cluster bug, manual failover may abort because of the master
sending PINGs to the replicas.
The following is the full list of commmits.
Regards,
Salvatore

Redis 5.0.4 Released Mon Mar 18 17:12:53 CET 2019
================================================================================
Upgrade urgency HIGH: This release fixes several Redis stability issues.
Dear Redis users, this release includes a number of fixes for bugs that may
result in Redis crashing in special conditions (not normal usage, but specific
artificial conditions), fixes to certain Redis behaviors especially around
Redis streams, and finally a set of new APIs for Redis Modules.
Specifically:
* Hyperloglog different coding errors leading to potential crashes were fixed.
* A replication bug leading to a potential crash in case of plain misuse of handshake commands was fixed.
* XCLAIM command incrementing of number of deliveries was fixed.
* LFU field management in objects was improved.
* A potential overflow in the redis-check-aof was fixed.
* A memory leak in case of API misuse was fixed.
* ZPOP* behavior when count is 0 is fixed.
* A few redis-cli --cluster bugs were fixed, plus a few improvements.
* Many other smaller bugs.
We suggest to upgrade Redis, especially in case your instance is facing
untrusted users (for instance Cloud providers) because several of these
bugs could result in unwanted crashes.

Redis 5.0.3 Released Tue Dec 11 18:17:26 CET 2018
================================================================================
Upgrade urgency HIGH: Redis 5 is consolidating, upgrading is a good idea.
However there is nothing very critical here, but certain
issues resolved could lead to very rare crashes.
Welcome to Redis 5.0.3, several interesting bug fixes here:
* Redis no longer panics when you send data to a replica-mode connection that
is in MONITOR or SYNC mode.
* Fixes to certain sorted set edge cases. You are unlikely to ever notice those
issues, but now it is more correct.
* Certain BSD variants now are better supported: build & register logging
on crash.
* The networking core now recovers if an IPv6 address is listed in bind but
is actually not able to work because there is no such protocol in the
system.
* redis-cli cluster mode improved in many ways. Especially the fix subcommand
work was enhanced to cover other edge cases that were still not covered
after the work done for Redis 5.
* MEMORY USAGE is now more accurate.
* DEBUG DIGEST-VALUE added in case you want to make sure a given set of keys
(and not the whole DB) are excatly the same between two instances.
* Fix a potential crash in the networking code related to recent changes
to the way the reply is consumed.
* Reject EXEC containing write commands against an instance that changed role
from master to replica during our transaction.
* Fix a crash in KEYS and other commands using pattern matching, in an edge
case where the pattern contains a zero byte.
* Fix eviction during AOF loading due to maxmemory triggered by commands
executed in loading state.
The following is the list of commmits if you want to check credits or dig
further in the details.
commit 2c6ee0f9b3d9ca48c6da8bd18796186784216bff
Author: antirez <[email protected]>
Date: Wed Dec 12 11:37:15 2018 +0100
freeMemoryIfNeeded() small refactoring.
Related to issue #5686 and PR #5689.
commit 107e93e75acfd5def0252efb6870751940816395
Author: zhaozhao.zz <[email protected]>
Date: Wed Dec 12 00:25:24 2018 +0800
evict: don't care about mem if loading
When loading data, we call processEventsWhileBlocked
to process events and execute commands.
But if we are loading AOF it's dangerous, because
processCommand would call freeMemoryIfNeeded to evict,
and that will break data consistency, see issue #5686.

Redis 5.0.2 Released Thu Nov 22 11:22:37 CET 2018
================================================================================
Upgrade urgency: CRITICAL if you use streams and consumer groups.
HIGH if you use redis-cli with Redis Cluster.
LOW otherwise.
Welcome to Redis 5.0.2. This release fixes two issues with Streams consumer
groups, where items could be returned duplicated by XREADGROUP when accessing
the history, and another bug where XREADGROUP can report some history even
if the comsumer pending list is empty. Both problems were addressed and unit
tests to avoid regressions implemented. Moreover this release fixes some
issue with redis-cli when in cluster mode. Finally some FreeBSD and DragonFly
build problems are now resolved. The list of the commits is below.
Enjoy,
Salvatore

Redis 5.0.1 Released Wed Nov 07 13:09:30 CET 2018
================================================================================
Upgrade urgency: URGENT if you use Redis Streams. MODERATE otherwise.
Hi all, this is the first patch level release of Redis 5. It contains
both fixes and improvements. Here there is a list of the major ones, however
read the commit messages at the end of the changelog if you want to know
more about the smaller things. Let's start with the new features:
* Sentinel now supports authentication! Check the Sentinel official doc
for more info.
* Redis-cli cluster "fix" is now able to fix a big number of clusters put
in a bad condition. Previously many corner cases were not covered.
Now the critical fixes:
1. Fix RESTORE mismatch reply when certain keys already expired.
2. Fix an XCLAIM non trivial issue: sometimes the command returned a wrong
entry or desynchronized the protocol.
And now the other fixes:
3. Stack trace generation on the Raspberry PI (and 32bit ARM) fixed.
4. Don't evict expired keys when the KEYS command is called, in order to
avoid a mass deletion event. However expired keys are not displayed
by KEYS as usually.
5. Improvements in the computation of the memory used, when estimating
the AOF buffers.
6. XRANGE COUNT of 0 fixed.
7. "key misses" stats accounting fixed. Many cache misses were not counted.
8. When in MULTI state, return OOM while accumulating commands and there
is no longer memory available.
9. Fix build on FreeBSD and possibly others.
10. Fix a crash in Redis modules, thread safe context reply accumulation.
11. Fix a race condition when producing the RDB file for full SYNC.
12. Disable protected mode in Sentinel.
13. More commands now have the HELP subcommand.
14. Fixed an issue about adaptive server HZ timer.
15. Fix cluster-replica-no-failover option name.
Finally, this is the list of commits. Enjoy Redis 5.0.1!

To start a quick recap of what's new in Redis 5:
1. The new Stream data type. https://redis.io/topics/streams-intro
2. New Redis modules APIs: Timers, Cluster and Dictionary APIs.
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
13. CLIENT UNBLOCK and CLIENT ID.
14. The LOLWUT command was added. http://antirez.com/news/123
15. We no longer use the "slave" word if not for API backward compatibility.
16. Differnet optimizations in the networking layer.
17. Lua improvements:
- Better propagation of Lua scripts to replicas / AOF.
- Lua scripts can now timeout and get in -BUSY state in the replica as well.
18. Dynamic HZ to balance idle CPU usage with responsiveness.
19. The Redis core was refactored and improved in many ways.
However the list above really does not do justice to the changes of Redis 5
since the core was improved in many ways during the development of the new
version. However certain changes were back ported into Redis 4 once they were
sensed as safe, because many improvements were hard to distinguish from fixes.
The most important user facing improvement is without doubts the introduction
of the new general purpose data type after years: the streams.
Note that we worked to improve and fix streams till a few hours ago, so while
we are not aware of critical bugs in this release, surely there is to handle it
with some care for the first weeks. Bug reporting will be highly appreciated and
we are ready to work immediately to release 5.0.1 once there is enough important
stuff to justify a new release (probably soon).
People not using the streams can have probably a better production-ready
experience with Redis 5, also because many internals are shared with Redis 4
so the jump is not as big as it was between 3.2 and 4 in terms of how things
internally work.
Well, many thanks to the Redis community and the developers that made
this release possible, contributing bug reports, patches, new features, working
on the clients, sometimes debugging problems for days. Also thank to everybody
that adopted Redis for their use cases making things work for users worldwide.
The list of commits in this release follows.
Cheers,
Salvatore
