Redis 2.6 release notes
+=======================
-Migrating from 2.4 to 2.6
-=========================
-
-Redis 2.4 is mostly a strict subset of 2.6. However there are a few things
-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
- for the time needed to perform the version upgrade.
+** IMPORTANT ** Check the 'Migrating from 2.4 to 2.6' section at the end of
+ this file for information about what changed between 2.4 and
+ 2.6 and how this may affect your application.
-There are also a few API differences, that are unlikely to cause problems,
-but it is better to keep them in mind:
-
-* SORT now will refuse to sort in numerical mode elements that can't be parsed
- as numbers.
-* EXPIREs now all have millisecond resolution (but this is very unlikely to
- break code that was not conceived exploting the previous resolution error
- in some way.)
-* INFO output is a bit different now, and contains empty lines and comments
- starting with '#'. All the major clients should be already fixed to work
- with the new INFO format.
-
-Also the following redis.conf and CONFIG GET / SET parameters changed name:
+What's new in Redis 2.5.9 (aka 2.6 Release Candidate 3)
+=======================================================
- * hash-max-zipmap-entries, now replaced by hash-max-ziplist-entries
- * hash-max-zipmap-value, now replaced by hash-max-ziplist-value
- * glueoutputbuf option was now completely removed (was deprecated)
+UPGRADE URGENCY: critical, upgrade ASAP.
----------
-CHANGELOG
----------
+* [BUGFIX] Fix for issue #500 (https://github.com/antirez/redis/pull/500).
+ Redis 2.6-RC1 and RC2 may corrupt ziplist-encoded sorted sets
+ produced by Redis 2.4.x.
+* [BUGFIX] Fixed several bugs in init.d script.
+* [BUGFIX] syncio.c functions modified for speed and correctness. On osx
+ (and possibly other BSD-based systems) the slave would block on
+ replication to send the SYNC command when the master was not
+ available. This is fixed now, but was not affecting Linux installs.
+* Now when slave-serve-stale-data is set to yes and the master is down, instead
+ of reporting a generic error Redis replies with -MASTERDOWN.
What's new in Redis 2.5.8 (aka 2.6 Release Candidate 2)
=======================================================
* Better support for big endian and *BSD systems.
* Build system improved.

+
+The following INFO fields were renamed for consistency:
+
+ changes_since_last_save -> rdb_changes_since_last_save
+ bgsave_in_progress -> rdb_bgsave_in_progress
+ last_save_time -> rdb_last_save_time
+ last_bgsave_status -> rdb_last_bgsave_status
+ bgrewriteaof_in_progress -> aof_rewrite_in_progress
+ bgrewriteaof_scheduled -> aof_rewrite_scheduled
+
+The following redis.conf and CONFIG GET / SET parameters changed:

+ * hash-max-zipmap-entries, now replaced by hash-max-ziplist-entries
+ * hash-max-zipmap-value, now replaced by hash-max-ziplist-value
