+Redis 5.0.0     Released Wed Oct 17 13:28:26 CEST 2018
+================================================================================
+
+Upgrade urgency CRITICAL: Several fixes to streams AOF and replication.
+
+Hi all and welcome to the first stable release of Redis 5! \o/
+
+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. https://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 slaves / AOF.
+    - Lua scripts can now timeout and get in -BUSY state in the slave 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
