+Redis 4.0.3     Released Thu Nov 30 13:14:50 CET 2017
+================================================================================
+
+Upgrade urgency CRITICAL: Several PSYNC2 bugs can corrupt the slave data set
+                          after a restart and a successful PSYNC2 handshake.
+
+Hi all, Redis 4.0.3 contains several bug fixes to different parts of Redis 4.0,
+but the highlight is definitely in the "PSYNC after restart" that the new
+RDB format, containing replication metadata information, was able to provide
+to Redis 4.0. There were several bugs that are addressed in this release.
+Moreover several LFU fixes improve the ability of Redis to correctly estimate
+the popularity of keys. This release also fixes important bugs in Redis modules,
+including bugs related to replication of modules commands, reloading the same
+module multiple times, and other related things. Finally there is even a
+security fix related to loading a corrupted Cluster state from a corrupted
+file. We advice to upgrade ASAP. Check the list of commits for credits, several
+people helped a lot in this release. I'm grateful to each of them.
+
+Cheers,
+Salvatore
