The Cyrus team is proud to announce the immediate availability of a new
version of Cyrus IMAP: 3.1.1

This is a snapshot of the master branch, and should be considered for
testing purposes and bleeding-edge features only. It is available as a
git tag only, which can be found here:

This is the last commit point on the master branch at which the JMAP
implementation is compatible with the experimental version in 3.0.x. 
>From this point onwards, the JMAP implementation will be changing
rapidly as the specification reaches formalisation.

Please note that recent security fixes for CVE-2017-12843 are NOT
included at this commit, so if you use this development version you will
need to backport the fixes (6a20366 and d734a23) from the master branch.

Join us on Github at to report
issues, join in the deliberations of new features for the next Cyrus
IMAP release, and to contribute to the documentation.

On behalf of the Cyrus team,

Kind regards,
