# UPGRADE URGENCY: MODERATE for Redis and Sentinel.
* [FIX] Makefile compatibility with non common make variants improved.
* [FIX] SDIFF crash in very unlikely to trigger state fixed.
* [FIX] Config rewriting fixed: don't wipe options unknown to the rewrite
process.
* [FIX] Set TCP port to 0 works again to disable TCP networking.
* [FIX] Fixed replication with old Redis instances as masters by not
sending REPLCONF ACK to them.
* [FIX] Fix keyspace notifications rewrite and CONFIG GET output.
* [FIX] Fix RESTORE TTL handling in 32 bit systems (32 bit overflow).
* [NEW] Sentinel now has a run time configuration API.
* [NEW] Log when we lost connection with master or slave.
* [NEW] When instance is turned from slave to master now inherits the
old master replication offset when possible. This improves the
Sentinel failover procedure.
</ChangeLog>
Use modern name for dependent libraries.

# UPGRADE URGENCY: MODERATE for Redis, HIGH for Sentinel.
* [FIX] Sentinel instance role sampling fixed, the system is now more
reliable during failover and when reconfiguring instances with
non matching configuration.
* [FIX] Inline requests are now handled even when terminated with just LF.
* [FIX] Replication timeout handling greatly improved, now the slave is able
to ping the master while removing the old data from memory, and while
loading the new RDB file. This avoid false timeouts sensed by
masters.
* [FIX] Fixed a replication bug involving 32 bit instances and big datasets
hard to compress that resulted into more than 2GB of RDB file sent.
* [FIX] Return error for inline requests with unbalanced quotes.
* [FIX] Publish the slave replication offset even when disconnected from the
master if there is still a cached master instance.
</ChangeLog>
<ChangeLog>
# UPGRADE URGENCY: MODERATE for both Redis and Sentinel.
* [FIX] Sentinel better desynchronization to avoid split-brain elections
where no Sentinel managed to get elected.
* [FIX] Stop accepting writes on "MISCONF" error only if master, not slave.
* [FIX] Reply to PING with an error on "MISCONF" errors.
</ChangeLog>

# UPGRADE URGENCY: LOW for Redis, CRITICAL for Senitnel. You don't need to
upgrade your Redis instances but it is highly recommended
to upgrade and restart all the Sentinel processes.

* [FIX] Fixed a false positive in Redis tests.
</ChangeLog>
<ChangeLog>
# UPGRADE URGENCY: LOW, unless you want to upgrade to new Sentinel code.

* [NEW] Log the new master when SLAVEOF command is used.
* [NEW] Sentinel code synchronized with the unstable branch, the new Sentinel
is a reimplementation that uses more reliable algorithms.

UPGRADE URGENCY: MODERATE
Warning: this release of Redis introduces a different behavior in MULTI/EXEC
handling of errors. This was done because the new behavior is safer
compared to the old one, and should not break any code targeting
Redis 2.6 in a critical way.
For more information check http://redis.io/topics/transactions
* [IMPROVED] RDB/AOF childern now log amount of additional memory used
because of copy on write.

* [BUGFIX] Fix integer overflow in zunionInterGenericCommand resulting
into Z[INTER|UNION][STORE] commands to crash under extremely
unlikely conditions (almost impossible in real world).

- Fixed a not critical but important VM bug: from time to time a race
condition may happen and a client may never get the reply from a given
request.
- Now we have a make install target as stated in the README.
- redis-cli no longer tries to understand if it's part of a pipe
so there is to use the -x option to read the last arg from stdin.
This prevents it from creating problem when running inside cron scripts.
- Fixed the init script provided in the tar.gz. It was totally broken.
- Fixed a bug related to connecting more than 10k clients to Redis.

Redis 1.2.6 fixes two critical replication bugs, and a few
improvements.
- Fixed Issue 207 (http://code.google.com/p/redis/issues/detail?id=207)
(broken replication with binary arguments not in the last position
with the MSET command or any other command issued with new
multi-bulk protocol).
- Fixed Issue 174 (http://code.google.com/p/redis/issues/detail?id=174)
(temp names collisions producing broken slave-side .rdb files).
- Redis-cli backported from Redis master, with interactive mode, line
editing via the linenoise library, auth ability, and much more.
- ZRANGEBYSCORE now supports WITHSCORES as well (backported from
master).
- A simplified version of redis-stat (from redis tools) added.

Redis 1.2.5 fixes a replication bug: multiple slaves
connecting to the same master could lead to random
crashes or corruptions.
</ChangeLog>
Feature safe: yes
<ChangeLog>
redis-1.2.2 is a bugfix release, fixing a problem with BGSAVE and BGREWRITEAOF
copy-on-write semantics. This version of Redis will use a lot less CPU and
memory while performing a BGSAVE and BGREWRITEAOF operation.
It is very important to upgrade ASAP to this version if you are using Redis
with data persistence via snapshotting or append only file.
Another minor change is that the INFO command will now have a new field showing
memory usage in an human readable form. This was backported from Redis unstable
as well.
</ChangeLog>
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.
