-What's new in Redis 2.6.0
-=========================
+What's new in Redis 2.5.9 (aka 2.6 Release Candidate 3)
+=======================================================
+
+UPGRADE URGENCY: critical, upgrade ASAP.
+
+* [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.

-                 upgrade after some testing of the application with the new

+* [BUGFIX] Fix for KEYS command: if the DB contains keys with expires the KEYS
+           command may return the wrong output, having duplicated or missing
+           keys. See issue #487 and #488 on github for details.

+What's new in Redis 2.5.7 (aka 2.6 Release Candidate 1)
+=======================================================
+
+UPGRADE URGENCY: upgrade not recommended because this is an RC release.

+* This is the first release candidate for Redis 2.6. We are not aware of
+  bugs, but part of this code is young and was never tested in production
