UPGRADE URGENCY: LOW, however updating is encouraged if you have many instances
per server and you want to lower the CPU / energy usage.
* [BUGFIX] Replication: more strict error checking for master PING reply.
* [BUGFIX] redis-cli: use keepalive socket option for improved reliability.
* [BUGFIX] Allow AUTH while loading the DB in memory.
* [BUGFIX] Don't segfault on unbalanced quotes while parsing config file.
* [IMPROVED] serverCron() frequency is now a runtime parameter (was REDIS_HZ).
* [IMPROVED] Use a lot less CPU when idle, even with many configured DBs.

<ChangeLog>
* [BUGFIX] Fixed compilation on FreeBSD.
* [IMPROVED] SRANDMEMBER <count> that returns multiple random elements.
* [IMPROVED] Sentinel backported to 2.6. It will be taken in sync with 2.8.
* [IMPROVED] Helper function for scripting to return errors and status replies.
* [IMPROVED] SORT by nosort [ASC|DESC] uses sorted set elements ordering.
* [BUGFIX] Better resistence to system clock skew.
* [IMPROVED] Warn the user when the configured maxmemory seems odd.
* [BUGFIX] Hashing function is now murmurhash2 for security purposes.

UPGRADE URGENCY: HIGH
* [BUGFIX] Theoretical bug in ziplist fixed.
* [BUGFIX] Better out of memory handling (Log produced in log file).
* [BUGFIX] Incrementally flush RDB file on slave side while performing the
first synchronization with the master. This makes Redis less
blocking in environments where disk I/O is slow.
* [BUGFIX] Don't crash with Lua's redis.call() without arguments.
* [BUGFIX] Don't crash after a big number of Lua calls on 32 bit systems
because of a failed assertion.
* [BUGFIX] Fix SORT behaviour when called from scripting.
* [BUGFIX] Adjust slave PING period accordingly to REDIS_HZ define.
* [BUGFIX] BITCOUNT: fix crash on overflowing arguments.
* [BUGFIX] Return an error when SELECT argument is not an integer.
* [BUGFIX] Blocking operations on lists were completely reimplemented for
correctness. Now blocking list ops and pushes originated from
Lua scripts will play well together and will be replicated
and transmitted to the AOF correctly.
* [IMPROVED] Send async PING before starting replication to avoid blocking if
master allows us to connect but it is actually not able to reply.
* [IMPROVED] Support slave-priority for Redis Sentinel.
* [IMPROVED] Hiredis library updated.

Adopt patch for redis.conf.
Previously and by default redis was compiled with debugging
information, that didn't respect CFLAGS. So, now its
possible to compile with debugging information by use
WITH_DEBUG knob.
Take maintainership.
