[release] Redis 3.0.3 is out!

[Salvatore Sanfilippo]

Hello,

Redis 3.0.3 is out with a few interesting changes. A few highlights:

1. Ever noticed blocking operations timeout much longer than the one
specified, when many clients are connected at the same time? Now this
is gone.
2. Solaris compilation of Redis 3.0 is fixed in 3.0.3.
3. EXISTS is now variadic, returning the number of keys that exist
among the ones specified.

Full changelog:

--[ Redis 3.0.3 ] Release date: 17 Jul 2015

Upgrade urgency: LOW for Redis and Sentinel.

* [FIX] Fix blocking operations timeout precision when HZ is at its default
value (not increased) and there are thousands of clients connected
at the same time. This bug affected Sidekiq users that experienced
a very long delay for BLPOP and similar commands to return for
timeout. Check commit b029ff1 for more info. (Salvatore Sanfilippo)
* [FIX] MIGRATE "creating socket: Invalid argument" error fix. Check
issues #2609 and #2612 for more info. (Salvatore Sanfilippo)
* [FIX] Be able to connect to the master even when the slave is bound to
just the loopback interface and has no valid public address in the
network the master is reacahble. (Salvatore Sanfilippo)
* [FIX] ZADD with options encoding promotion fixed. (linfangrong)
* [FIX] Reset aof_delayed_fsync on CONFIG RESETSTATS. (Tom Kiemes)
* [FIX] PFCOUNT key parsing in cluster fixed. (MOON_CLJ)
* [FIX] Fix Solaris compilation of Redis 3.0. (Jan-Erik Rediger)

* [NEW] Variadic EXISTS command. Now the command accepts multiple arguments
and returns the total count of existing keys.

Cheers,
Salvatore
