The Cyrus team is proud to announce the immediate availability of a new
version of Cyrus IMAP: 2.4.20.

This is a bug fix release for the old 2.4 series.  It should not be used
for new Cyrus installations, but may be useful to administrators of 2.4
murders who are migrating to 3.0.

The previous 2.4.19 release updated the XFER command to properly support
XFER to 2.5 and 3.0 servers, but also introduced an lmtpd crash.  This
release contains the fix for the lmtpd crash, so if you are migrating a
2.4 murder to 3.0, this will help.
