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 3.8.2. Documentation at

Development Version

Latest development snapshot is 3.9.0-alpha0. Documentation at


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.
