> A few minor changes since v2.2.13.rc1, mainly making the Pigeonhole  
> tests pass.
>
> 	* Fixed a DoS attack against imap/pop3-login processes. If SSL/TLS
> 	  handshake was started but wasn't finished, the login process
> 	  attempted to eventually forcibly disconnect the client, but failed
> 	  to do it correctly. This could have left the connections hanging
> 	  arond for a long time. (Affected Dovecot v1.1+)
>
> 	+ mdbox: Added mdbox_purge_preserve_alt setting to keep the file
> 	  within alt storage during purge. (Should become enforced in v2.3.0?)
> 	+ fts: Added support for parsing attachments via Apache Tika. Enable
> 	  with: plugin { fts_tika = http://tikahost:9998/tika/ }
> 	+ virtual plugin: Delay opening backend mailboxes until it's necessary.
> 	  This requires mailbox_list_index=yes to work. (Currently IMAP IDLE
> 	  command still causes all backend mailboxes to be opened.)
> 	+ mail_never_cache_fields=* means now to disable all caching. This may
> 	  be a useful optimization as doveadm/dsync parameter for some admin
> 	  tasks which shouldn't really update the cache file.
> 	+ IMAP: Return SPECIAL-USE flags always for LSUB command.
> 	- pop3 server was still crashing in v2.2.12 with some settings
> 	- maildir: Various fixes and improvements to handling compressed mails,
> 	  especially when they have broken/missing S=sizes in filenames.
> 	- fts-lucene, fts-solr: Fixed crash on search when the index contained
> 	  duplicate entries.
> 	- Many fixes and performance improvements to dsync and replication
> 	- director was somewhat broken when there were exactly two directors
> 	  in the ring. It caused errors about "weak users" getting stuck.
> 	- mail_attachment_dir: Attachments with the last base64-encoded line
> 	  longer than the rest wasn't handled correctly.
> 	- IMAP: SEARCH/SORT PARTIAL was handled completely wrong in v2.2.11+
> 	- acl: Global ACL file handling was broken when multiple entries
> 	  matched the mailbox name. (Only the first entry was used.)
