OpenStack Releases

Release Series

OpenStack is developed and released around 6-month cycles. After the initial release, additional stable point releases will be released in each release series. You can find the detail of the various release series here on their series page. Subscribe to the combined release calendar for continual updates.

Series-Independent Releases

Some projects are released independently from the OpenStack release series. You can find their releases listed here:

Cryptographic Signatures

Git tags created through our release automation are signed by centrally-managed OpenPGP keys maintained by the OpenStack Infrastructure team. Detached signatures of many separate release artifacts are also provided using the same keys. A new key is created corresponding to each development cycle and rotated relatively early in the cycle. (Implementation completed late in the Newton cycle, so many early Newton artifacts have no corresponding signatures.)

OpenStack Infrastructure root sysadmins and Release Managers publish their own signatures of these keys into the global keyserver network. Copies of the public keys can be found below along with the date ranges during which each key was in general use.
