+What's new in Redis 2.2.8
+* A new form of dict.c (hash table implementation) iterator that performs less
+ copy-on-write of pages, introduced in Redis 2.2.7, caused ZINTERSTORE,
+ ZUNIONSTORE, SINTER, SINTERSTORE commands to behave in the wrong way.
+* Print version info before running the test with 'make test'. This is mainly
+ useful for the Continuous Integration system we run.
+* Fix for DEBUG DIGEST, key may expire on lookup, producing the wrong result.
+* Replication with expire test modified to produce no or less false failures.
+* Fixed Z*STORE when dealing with intsets, regression test added.
