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).
