Hopefully one of the last v2.0.x releases.

	- IMAP: ENABLE CONDSTORE/QRESYNC + STATUS for a mailbox might not
	  have seen latest external changes to it, like new mails.
	- imap_id_* settings were ignored before login.
	- doveadm altmove did too much work sometimes, retrying moves
	  it had already done.
	- mbox: Fixed accessing Dovecot v1.x mbox index files without errors.
