Redis 5.0.5:

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.
