+Virtual Router Out of Band reboots configurable
+-----------------------------------------------
+
+ As of Apache CloudStack 4.4.4 it is now configurable how Out of Band reboots of Virtual Routers should be treated.
+ A new setting ``router.reboot.when.migrated`` is introduced wich defaults to ``false``.
+
+ This behaviour changed in Apache CloudStack 4.4.3, and to restore that behaviour the setting should be set to ``true``.

+Duplicate SSH Keys are no longer allowed

+In previous versions you could register the same SSH Public Key more than once in the same account.
