Here's the first beta release of Dovecot v2.1. This version has already
been tested quite a lot, so I'm not expecting any major bugs. So please
upgrade and see if you can find any problems. I'm optimistic about
getting rc1 released this year and perhaps even v2.1.0.

Since alpha2 there have been a lot of fixes, especially to imapc
backend. There are probably also some small new features, but nothing

As a reminder, here's the largest changes since v2.0:

	* Plugins now use UTF-8 mailbox names rather than mUTF-7:
	  acl, autocreate, expire, trash, virtual
	* auth_username_format default changed to %Lu. If you really want
	  case sensitive usernames, set it back to empty.
	* Solr full text search backend changed to use mailbox GUIDs instead of
	  mailbox names, requiring reindexing everything. solr_old backend can
	  be used with old indexes to avoid reindexing, but it doesn't support
	  some newer features.

	+ imapc (= IMAP client) storage allows using a remote IMAP server to
	  be used as storage. This allows using Dovecot as a smart (caching)
	  proxy or using dsync to do migration from remote IMAP server.
	+ Mailbox indexing via queuing indexer service (required for Lucene)
	+ Lucene full text search (FTS) backend rewritten with support for
	  different languages
	+ FTS finally supports "OR" search operation
	+ FTS supports indexing attachments via external programs
	+ IMAP FUZZY extension, supported by Lucene and Solr FTS backends
	+ Mailbox list indexes
	+ Statistics tracking via stats service. Exported via doveadm stats.
	+ Autocreate plugin creates/subscribes mailboxes physically only when
	  the mailbox is opened for the first time. Mailbox listing shows the
	  autocreated mailboxes even if they don't physically exist.
	+ Password and user databases now support default_fields and
	  override_fields settings to specify template defaults/overrides.
	- listescape plugin works perfectly now
