v2.1.0 had a couple of bugs, but overall people have been pretty quiet
about it. I'm hoping v2.1.2 won't need to be released for many more
weeks. :)

BTW. v2.2 branch has also been opened in hg. Not much stuff in there yet
though.

	+ dsync: If message with same GUID is saved multiple times in session,
	  copy it instead of re-saving. 
	- acl plugin + autocreated mailboxes crashed when listing mailboxes
	- doveadm force-resync: Don't skip autocreated mailboxes (especially
	  INBOX). 
	- If process runs out of fds, stop listening for new connections only
	  temporarily, not permanently (avoids hangs with process_limit=1
	  services)
	- auth: passdb imap crashed for non-login authentication (e.g. smtp).
