# 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.
<ChangeLog>
# 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>
<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 bug in "new Sentinel" config propagation.
* [FIX] Fixed a false positive in Redis tests.
</ChangeLog>
<ChangeLog>
UPGRADE URGENCY: MODERATE.
* [FIX] Stop writes when fork() fails when trying to BGSAVE. BGSAVE errors
were trapped only in the case the saving child failed, so the fork()
error was no trapped as no child is created at all.
* [FIX] Fix a serious memory efficiency regression, Redis 2.6.16 is
significantly better with large values (>= a few kbytes) and will
be able to store two times the amount of data compared to Redis 2.6.15
when values are in that range.
* [FIX] Fixed an issue with Table conversion in the lua-cmsgpack library exposed
by the Redis scripting engine.
* [NEW] DEBUG SDSLEN was introduced to debug memory inefficiencies due to
SDS allocation more easily.
</ChangeLog>
Add support for lang/lua, disabled by default.
<ChangeLog>
UPGRADE URGENCY: MODERATE, upgrade ASAP only if you experience issues related to
the expired keys collection algorithm, or if you use the
ZUNIONSTORE command.
* [FIX] Improved expired keys collection algorithm. Even under heavy load keys
to be expired can't accumulate because of lack of CPU time.
* [FIX] Fixed Issue #1240, ZUNIONSTORE could lead to wrong result.
* [NEW] redis-benchmark improvements.
* [NEW] dict.c API wrong usage detection.
WARNING: redis-benchmark released with 2.6.15 features non backward compatible
change in the way the random arguments are specified, use the --help
option for more information.

UPGRADE URGENCY: HIGH because of the following two issues:
* Lua scripting + Replication + AOF in slaves problem (see Issue #1164).
* AOF + expires possible race condition (see Issue #1079).
* [FIX] AOF bug: expire could be removed from key on AOF rewrite.
* [FIX] Allow writes from scripts called by AOF loading in read-only slaves.
* [FIX] Sentinel: parse new verison of INFO replication output correctly.
* [NEW] Reset masterauth if an empty string is configured.

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

because of copy on write.

unlikely conditions (almost impossible in real world).

literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().
In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.

* [BUGFIX] Fixed issue #141 part 1: Possible protocol desyncs when clients send
wrong protocol is now fixed. (See issue 141 for more details)
* [BUGFIX] Fixed issue #141 part 2: Connection of multiple slaves used to result
from time to time into corrupted protocol send to slaves connected
after the first one. (See issue 141 for more details)
