Release Notes
*************

Cyrus uses an odd-even release cycle.

With our versioning system using "major.minor.micro" numbering, the
minor (middle) number reveals whether a version is stable (even), or
development-only (odd).

A 3.**0**.1 release is stable, but a 3.**1**.4 release is
developmental only.


Stable Version
==============

Latest stable version is . Documentation at
https://www.cyrusimap.org/.


Development Version
===================

Latest development snapshot is . Documentation at
https://www.cyrusimap.org/dev/.

Warning:

  Development versions are tagged snapshots of the master branch, and
  should be considered for **testing purposes** and **bleeding-edge
  features** only. We will try to tag these snapshots at coherent
  development points, but there will generally be **large breaking
  changes** occurring between releases in this series.
