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:

+* 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

+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

* 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
