CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP.
--------------------------------------------------------------------------------
+---[ Redis 2.5.12 (2.6 Release Candidate 6) ]
+
+UPGRADE URGENCY: MODERATE.
+
+* [BUGFIX] Fixed a timing attack on AUTH (Issue #560).
+* [BUGFIX] Don't assume that "char" is signed.
+* [BUGFIX] Check that we have connection before enabling pipe mode.
+* [BUGFIX] Use the optimized version of the function to convert a double to
+ its string representation. Compilation was disabled because of
+ a typo in the #if statement.
+* [IMPROVED} REPLCONF internal command introduced, now INFO shows slaves with
+ correct port numbers. This makes 2.5.12 Redis Sentinel compatible.
+* [IMPROVED] Truncate short write from the AOF for a cleaner restart. On short
+ writes (for instance out of space) Redis will now try to remove
+ the half-written data so that the next restart will work without
+ the need for the "redis-check-aof" utility.
+* [IMPROVED] New in INFO: aof_last_bgrewrite_status
+* [IMPROVED] Allow Pub/Sub in contexts where other commands are blocked.
+* [BUGFIX] mark fd as writable when EPOLLERR or EPOLLHUP is returned by
+ epoll_wait.

UPGRADE URGENCY: HIGH.
that you should be aware of:
* You can't use .rdb and AOF files generated with 2.6 into a 2.4 instance.
-* 2.4 slaves can be attached to 2.6 masters, but not the contrary, and only
+* 2.6 slaves can be attached to 2.4 masters, but not the contrary, and only
for the time needed to perform the version upgrade.
There are also a few API differences, that are unlikely to cause problems,
