This could be (one of) the last v2.2.x release. We're starting v2.3 development soon.

 + Added mailbox { autoexpunge=<time> } setting. See
   http://wiki2.dovecot.org/MailboxSettings for details.
 + ssl_options: Added support for no_ticket
 + imap/pop3/managesieve-login: Added postlogin_socket=path passdb extra
   field. This allows replacing the default service
   imap/pop3/managesieve {} settings for specific users (e.g. running
   their imap process via valgrind or strace).
 + doveadm fetch: Added date.sent/received/saved.unixtime
 + fs-posix: Added mode=auto parameter to set the created files' and
   directories' mode based on the parent dir if it has setgid-bit.
 + director: Support backends having hostnames, which makes it possible
   to verify their SSL certificates.
 - director: Directors' state became desynchronized if doveadm director
   commands were used to modify the same backend in multiple directors
   at the same time with conflicting changes. This fix includes some
   extra checks, which makes sure that if such a conflict still happens
   it's automatically fixed. In some situations such an automatic fix
   may now be unnecessarily triggered and an error logged.
 - director: Backend tags weren't working correctly.
 - ldap: tls_* settings weren't used for ldaps URIs.
 - ldap, mysql: Fixed setting connect timeout.
 - auth: userdb lookups via auth-worker couldn't change username
 - dsync: Fixed handling deleted directories. Make sure we don't go to
   infinite mailbox renaming loop.
 - imap: Fixed crash in NOTIFY when there were watched namespaces that
   didn't support NOTIFY.
 - imap: After SETMETADATA was used, various commands (especially FETCH)
   could have started hanging when their output was large.
 - stats: Idle sessions weren't refreshed often enough, causing stats
   process to forget them and log errors about unknown sessions when
   they were updated later.
 - stats: Fixed "Duplicate session ID" errors when LMTP delivered to
   multiple recipients and fts_autoindex=yes.
 - zlib plugin: Fixed copying causing cache corruption when zlib_save
   wasn't set, but the source message was compressed.
 - fts-solr: Fixed escaping Solr query parameters.
 - lmtp: quota_full_tempfail=yes was ignored with
   lmtp_rcpt_check_quota=yes
