- acl: Global ACL file handling was broken when multiple entries
matched the mailbox name

- imap: Don't send HIGHESTMODSEQ anymore on SELECT/EXAMINE when

(When [NOMODSEQ] is returned by SELECT, mainly with in-memory

- stats plugin: Processes that only temporarily dropped privileges
(e.g. indexer-worker) may have been logging errors about not being

"--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.
- 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.
- master process was doing a hostname.domain lookup for each created
process, which may have caused a lot of unnecessary DNS lookups.
- dsync: Syncing over 100 messages at once caused problems in some
situations, causing messages to get new UIDs.
- fts-solr: Different Solr hosts for different users didn't work.
- director: v2.2.5 changes caused "SYNC lost" errors

- doveadm -A: Don't waste CPU by doing a separate config lookup
for each user

- mbox: Fixed mailbox_list_index=yes to work correctly
- added some missing man pages (by Pascal Volk)
- director: Users near expiration could have been redirected to
different servers at the same time.
- pop3: Avoid assert-crash if client disconnects during LIST.
- mdbox: Corrupted index header still wasn't automatically fixed.
- dsync: Various fixes to work better with imapc and pop3c storages.
- ldap: sasl_bind=yes caused crashes, because Dovecot's lib-sasl
symbols conflicted with Cyrus SASL library.
- imap/pop3 proxy: Master user logins were broken in v2.2.3
- sdbox/mdbox: A corrupted index header with wrong size was never
automatically fixed in v2.2.3.
- mbox: Fixed assert-crashes related to locking.

ENVELOPE reply with a huge literal value, effectively causing the
IMAP client to wait for more data forever.
- IMAP: Various URLAUTH fixes.
- imapc: Various bugfixes and improvements
- pop3c: Various fixes to make it work in dsync (without imapc)
- dsync: Fixes to syncing subscriptions. Fixes to syncing mailbox
renames.

- IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag.
- mailbox_list_index=yes still caused crashes.
- maildir: Fixed a crash after dovecot-keywords file was re-read.
- maildir: If files had reappeared unexpectedly to a Maildir, they
were ignored until index files were deleted.
- Maildir: Fixed handling over 26 keywords in a mailbox.
- imap/pop3-login proxying: Fixed a crash if TCP connection succeeded,
but the remote login timed out.
Some of the documentation in %docdir (wiki/Migration*.txt) uses perl as
an interpreter, which causes rpmbuild to autogenerate deps on perl.
Filter this out as it's not needed for the main dovecot functionality.

- Mailbox list indexes weren't using proper file permissions based
on the root directory.
- replicator: doveadm commands and user list export may have skipped
some users.
- Various fixes to mailbox_list_index=yes
- v2.1.11+ had a race condition where it sometimes overwrote data in
dovecot.index.cache file. This could have caused Dovecot to return
the same cached data to two different messages.
- mdbox: Fixes to handling duplicate GUIDs during index rebuild
- lmtp proxy: Fixed hanging if remote server was down.
- doveadm: Various fixes to handling doveadm-server connections.
- auth: passdb imap was broken in v2.1.10.
