Release Notes — Cyrus IMAP 3.12.2 documentation

# 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 3.12.2. Documentation at https://www.cyrusimap.org/.

## Development Version

Latest development snapshot is 3.13.3. 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.
