Upgrading Dovecot v2.1 to v2.2
==============================

v2.2 is compatible with v2.1 settings, but there are a couple of changes you
should be aware of:

 * When creating home directories, the permissions are copied from the parent
   directory if it has setgid-bit set. For full details, see
   <SharedMailboxes.Permissions.txt>.
 * "doveadm auth" command was renamed to "doveadm auth test"

Downgrading can be done safely to v2.1.11 and newer. Older versions may think
the dovecot.index.cache files are corrupted and complain about "Invalid magic
in hole header".
