this file for information about what changed between 2.4 and
2.6 and how this may affect your application.
+--------------------------------------------------------------------------------
+Upgrade urgency levels:
+
+LOW: No need to upgrade unless there are new features you want to use.
+MODERATE: Program an upgrade of the server, but it's not urgent.
+HIGH: There is a critical bug that may affect a subset of users. Upgrade!
+CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP.
+--------------------------------------------------------------------------------
+
+---[ Redis 2.5.13 (2.6 Release Candidate 7) ]
+
+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.
+
+---[ 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.
+
+---[ Redis 2.5.11 (2.6 Release Candidate 5) ]
+
+UPGRADE URGENCY: HIGH.
+
+* [BUGFIX] Fixed Hash corruption when loading an RDB file generated by
+ previous versions of Redis that encoded hashes using
+ a different ziplist encoding format for small integers.
+ All the fileds that are integers in the range 0-255 may not
+ be recognized, or duplicated un updates, causing a crash
+ when the ziplist is converted to a real hash. (Issue #547).
+* [BUGFIX] Fixed the count of memory used by output buffers in the
+ setDeferredMultiBulkLength() function.
+
+---[ Redis 2.5.10 (2.6 Release Candidate 4) ]
+
+UPGRADE URGENCY: HIGH.
+
+* [BUGFIX] Allow PREFIX to be overwritten on "make install".
+* [BUGFIX] Run the test with just one client if the computer is slow.
+* [BUGFIX] Event port support in our event driven libray.
+* [BUGFIX] Jemalloc updated to 3.0.0. This fixes a possibly AOF rewrite issue.
+ See https://github.com/antirez/redis/issues/504 for info.
+* [BUGFIX] Fixed issue #516: ZINTERSTORE / ZUNIONSTORE with mixed sets/zsets.
+* [BUGFIX] Set fd to writable when poll(2) detects POLLERR or POLLHUP event.
+* [BUGFIX] Fixed RESTORE hash failure (Issue #532).
+* [IMPROVED] Allow an AOF rewrite buffer > 2GB (Related to issue #504).
+* [IMPROVED] Server cron function frequency is now configurable (REDIS_HZ).
+* [IMPROVED] Better, less blocking expired keys collection algorithm.
+* [FEATURE] New commands: BITOP and BITCOUNT.
+* [FEATURE] redis-cli --pipe for mass import.
+
What's new in Redis 2.5.9 (aka 2.6 Release Candidate 3)
=======================================================
* Better memory usage for "small" lists, ziplists and hashes when fields or
values contain small integers.
* Read only slaves.
+* New bit opeations: BITCOUNT and BITOP commands.
* Clients max output buffer soft and hard limits. You can specifiy different
limits for different classes of clients (normal,pubsub,slave).
+* More incremental (less blocking) expired keys collection algorithm, in
+ practical terms this means that Redis is more responsive when a very
+ big number of keys expire about at the same time.
* AOF is now able to rewrite aggregate data types using variadic commands,
often producing an AOF that is faster to save, load, and is smaller in size.
* Every redis.conf directive is now accepted as a command line option for the
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,
