	+ Mail cache lookups work for the mail being saved. This improves
	  performance by avoiding the need to parse the mail multiple times
	  when using some plugins (e.g. mail_log).
	+ Mail cache works for recently cached data also with in-memory
	  indexes.
	+ imapc: Many performance improvements, especially when working with
	  dsync. Also added imapc_feature=fetch-headers which allows using
	  FETCH BODY.PEEK[HEADER.FIELDS (..)] to avoid reading the entire
	  header.
	+ mail_location = ..:FULLDIRNAME=dbox-Mails is the same as
	  :DIRNAME=dbox-Mails, but it will also be used for
	  :INDEX and :CONTROL directories. (It should have worked this way
	  from the beginning, but can't be changed anymore without breaking
	  existing installations).
	- Fixed infinite loop in message parsing if message ends with
	  "--boundary" and CR (without LF). Messages saved via SMTP/LMTP can't
	  trigger this, because messages must end with an "LF.". A user could
	  trigger this for him/herself though.
	- lmtp: Client was sometimes disconnected before all the output was
	  sent to it.
	- imap_zlib plugin caused crashes during client disconnection in
	  v2.2.7
	- replicator: Database wasn't being exported to disk every 15 minutes
	  as it should have. Instead it was being imported, causing "doveadm
	  replicator remove" commands to not work very well.
