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.
