 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.

.. note::
   The schedule of `Maintenance phases`_ changed during Ocata.
   The `old phases`_ were used until Newton.

.. _extended-maintenance-note:

.. note::
   If a branch is marked as Extended Maintenance, that means individual
   projects can be in state *Maintained*, *Unmaintained*, *Last* or
   *End of Life* on that branch. Please check specific project about its
   actual status on the given branch.

Series-Independent Releases
===========================

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

Teams
=====

Deliverables are produced by `project teams`_. Here you can find all OpenStack
deliverables, organized by the team that produces them:

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.
