Migrating from 2.4 to 2.6
=========================
-Redis 2.4 is mostly a strict subset of 2.6.
-The only thing you should be aware is that you can't use .rdb and AOF files
-generated with 2.4 into a 2.2 instance.
+Redis 2.4 is mostly a strict subset of 2.6. However there are a few things
+that you should be aware of:
-2.4 slaves can be attached to 2.2 masters, but not the contrary, and only for
-the time needed to perform the version upgrade.
+* 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.
-From the point of view of the API Redis 2.4 only adds new commands
-(other commands now accepts a variable number of arguments) so you don't need
-to modify your program in order to use Redis 2.4.

-However there are a few semantical differences that you should be aware of:
+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.
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 '#'.
+ 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:
+
+ * hash-max-zipmap-entries, now replaced by hash-max-ziplist-entries
+ * hash-max-zipmap-value, now replaced by hash-max-ziplist-value
+ * glueoutputbuf was no completely removed as it does not make sense

in slaves.
* Milliseconds resolution expires, also added new commands with milliseconds
precision (PEXPIRE, PTTL, ...).
-* Clinets max output buffer soft and hard limits. You can specifiy different
+* Clients max output buffer soft and hard limits. You can specifiy different
limits for different classes of clients (normal,pubsub,slave).
* 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.
