authentication was aborted/failed without a username set.
- director: If two users had different tags but the same hash,
the users may have been redirected to the wrong tag's hosts.

"Missing middle file seq=.." to be logged and index rebuild.
This happened more easily with IMAP hibernation enabled.
- Various fixes to restoring state correctly in un-hibernation.

is because 3 bytes per email were being wasted that could have been
used for IMAP keywords.

weren't handled correctly. They were incorrectly merged together.
- master process's listener socket was leaked to all child processes.
This might have allowed untrusted processes to capture and prevent
"doveadm service stop" comands from working.
- login proxy: Fixed crash when outgoing SSL connections were hanging.

from previous userdbs didn't work there.

had the same prefix as the parent.

been triggered at least by a Sieve script.

used in default_fields, override_fields or LDAP pass/user_attrs.
userdb result_* were also ignored when user was found from cache.

caught actual hangs or otherwise unwanted behavior towards IMAP

transform. It now extracts text for HTML message parts.

alt storage as well.

any configured master=yes passdbs

trigger this, because messages must end with an "LF.". A user could
trigger this for him/herself though.
- lmtp: Client was sometimes disconnected before all the output was
sent to it.
- replicator: Database wasn't being exported to disk every 15 minutes

automatically fixed in v2.2.3.
