[release] Redis 4.0.1 is out

[Salvatore Sanfilippo]

Hello, the first patch level release of Redis 4.0 is already here due
to the obvious last minute fixes.
Here is the official change log that says it all:

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
