A couple of changes since rc1:

 + Added apparmor plugin. See https://wiki2.dovecot.org/Plugins/Apparmor 
 - director: v2.2.31 caused rapid reconnection loops to directors
   that were down.

Also this was already in rc1's list of changes, but wasn't actually in rc1 yet:

 - dict-ldap: %variable values used in the LDAP filter weren't escaped.

Plus a few other smaller fixes.
