1============================== 2Cyrus IMAP 2.4.3 Release Notes 3============================== 4 5Changes to the Cyrus IMAP Server since 2.4.2 6 7* Many fixes to replication edge case handling 8* Added missing flags to reconstruct 9* Replicate DELETED.user folders in sync_client -u (matches XFER behaviour now) 10* Make sync_client only connect after forking in rolling mode. Fixes two things - ssl crashes due to shared resource conflicts, and also means master will start up even if the replica is not contactable 11* Fixed crash on cyr_expire and ipurge annotation based expiry 12* Many XFER fixes for compatibility across versions: 13* allowing XFER in from delayed_expunge mailboxes 14* allowing XFER back all the way to Cyrus 2.2.12. This was accomplished by adding logic that can generate backwards-compatible older version indexes, and version detection from the imapd banner. 15* correctly fixing seen information for sub-mailboxes on XFER in 16* Multi-target replication. Strictly this is a new feature - there was a broken implementation in 2.4.0, which is how this snuck in to the bugfix release. It's not super-well documented yet, but it works by creating a separate log file for each destination "channel", and then running one sync_client process per channel, so replication can fall behind on one without affecting replication to the other. 17* Fixed some crashes and errors which occured when upgrading and opening corrupted mailboxes 18* Modified AFS ptloader configure options to allow building on more modern systems 19 20:ref:`imap-release-notes-2.4` 21
