> 	  It can usually be updated incrementally, so this makes THREAD fast.
> 	+ Added Dovecot-specific X-REFERENCES2 threading algorithm.
> 	  It's similar to REFERENCES, but it doesn't do base subject merging
> 	  and it sorts the threads by their newest message.
> 	+ When saving messages, update cache file immediately with the data
> 	  that we expect client to fetch later. Maildir-only currently.
> 	+ NFS attribute and data caches are are flushed whenever needed.
> 	  See mail_nfs_storage and mail_nfs_index settings.
> 	+ Mailbox list indexes. Mailbox metadata is stored there, so STATUS
> 	  commands can return synchronized mailboxes' metadata simply by
> 	  reading a single mailbox list index file. Currently works only with
> 	  Maildir++ layout.
> 	+ Out of order command execution (SEARCH, FETCH, LIST), nonstandard
> 	  command cancellation (X-CANCEL <tag>)
> 	+ Expire plugin can be used to keep track of oldest messages in

> 	  messages from the mailboxes that have them. The tracking is done
> 	  using lib-dict, so you can use either Berkeley DB or SQL database.
> 	+ Namespaces are supported everywhere now.
> 	+ Full text search indexing support with Lucene and Squat backends.
> 	+ OTP and S/KEY authentication mechanisms (by Andrey Panin).
> 	+ mbox and Maildir works with both Maildir++ and FS layouts. You can
> 	  change these by appending :LAYOUT=maildir++ or :LAYOUT=fs to
> 	  mail_location.
> 	+ LDAP: Support templates in pass_attrs and user_attrs
> 	+ Support for listening in multiple IPs/ports.
> 	+ Quota plugin rewrite: Support for multiple quota roots, warnings,
> 	  allow giving storage size in bytes or kilo/mega/giga/terabytes,
> 	  per-mailbox quota rules.
