Cyrus IMAP 2.4.21, 2.5.16 and 3.0.14 released

[ellie timoney]

The Cyrus team is proud to announce the immediate availability of new legacy versions of Cyrus IMAP.

The primary motivator for these releases is to allow XFER to correctly recognise newer Cyrus backends.  If you run a legacy Cyrus installation in a murder configuration, and ever wish to upgrade your backends to 3.1, 3.2 or 3.3, you will need these fixes.  Details and discussion of this issue are available at https://github.com/cyrusimap/cyrus-imapd/issues/3123

If your legacy Cyrus installation is not in a murder configuration, please check the release notes to see if any of the other changes are things you care about.
