+================================================================================
+
+Upgrade urgency HIGH: not critical but very important bugs fixed.
+
+Dear users, this is just a bugfix release of Redis 4. All new work
+is now focused on Redis 5, however we backported a number of bug fixes here:
+
+* The disconnection time between the master and slave was reset in an
+  incorrect place, sometimes a good slave will not be able to failover
+  because it claims it was disconnected for too much time from the master.
+* A replication bug, rare to trigger but non impossible, is in Redis for
+  years. It was lately discovered at Redis Labs and fixed by Oran Agra.
+  It may cause disconnections, desynchronizations and other issues.
+* RANDOMKEY may go in infinite loop on rare situations. Now fixed.
+* EXISTS now works in a more consistent way on slaves.
+* Sentinel: backport of an option to deny a potential security problem
+  when the SENTINEL command is used to configure an arbitrary script
+  to execute.
+
+Many of these issues are there for a very long time, however upgrading
+is a good idea.
