I am pleased to announce the release of Cyrus IMAPd 2.3.9.  This release
should be considered production quality.  This release is currently 
deployed on the production Murder at CMU, as well as several other large 

This release fixes some bugs in the replication code, the handling of 
Sieve scripts when XFERing a mailbox between servers, and retains 
cyrus.expunge (and associated messages) when RENAMEing, XFERing, or 
replicating mailboxes.  This release also now disables plaintext 
authentication by default.  For full details, please see 
doc/changes.html and doc/install-upgrade.html which are included in the 

Please note that replication still does not work correctly for mailboxes
which have the IMAP CONDSTORE extension enabled on them.  Since most, if
not all, mainstream IMAP clients still do not have support for
CONDSTORE, this deficiency in Cyrus IMAP should not impact many sites.
It is expected that the next release will properly support replication
of CONDSTORE-enabled mailboxes.
