# Cyrus IMAP 2.4.13 Release Notes

Changes to the Cyrus IMAP Server since 2.4.12

- Bug #3565 - fix gcc compiler warnings - thanks Dilyan Palauzov <dilyan.palauzov@aegee.org>
- Bug #2685 - rename annots in delayed folder delete. Avoids annotations “reappearing” when a folder is recreated
- Bug #3566 - actually fix in a backward compatible way. 2.4.12 broke older versions of bison
- Lots of small cleanups from CMU as they prepared to build RSS into their 2.4 build. Thanks Ken
- Bug #3591/#3609 - fix crash in mupdate on partition move
- Bug #3610 - fix replication of partition move
- Bug #3564 - document the way prefork interacts with multiple network protocols
- Bug #3586 - allow rename of “\Noselect” if subfolders exist
- A handful of small cleanups (#3593, #3594, #3595) from David Carter <dpc22@cam.ac.uk>. Very much appreciated
- Disabled duplicate_check DEBUG level log messages by default. Thanks Philip Prindeville <philipp@redfish-solutions.com>
- Bug #3608 - log mailbox name in more sync failure cases
- Bug #3615 - fix proxyd_disable_mailbox_referrals. Thanks Andrew Morgan <morgan@orst.edu>
- Bug #3611 - fix crash in sync_mailbox_full if expunge fails
- Backported some nice fixes from master, including safer thread/sort (there were some crashes on bad messages before)
- Fixed infinite loop on suppress_capabilities with substrings of other capabilities. Ouch.
- Fixed LIST and LSUB again - this time to make LIST “” “*%” work without breaking other things
- Bug #3588 - make XFER not break if the wrong server name was used. The start of making murder safer
- Bug #3603 - tidied up usage of kick_mupdate so it never gets called on standard murder backends
- Bug #3604 - always suppress the `DELETED.*` mailbox names, even if delete_mode is immediate. It means a config change or different frontend won’t show undeletable mailboxes
- Bug #3602 - allow UpperCase in service names to work
