From 6b484ba69f7024b794f68ff917936aead3d74f98 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Tue, 12 Jul 2022 17:34:14 -0400 Subject: [PATCH] doc: Add doc/develop/release_cycle.rst Migrate the RelaseCycle wiki page to Sphinx. In terms of visible changes, we stop having a dynamic countdown to when the release is. And we drop the year-based statistics, that were not being kept up to date. For the moment, we only link to statistics for v2022.07 but will add back the historical data in a subsequent patch.

This is further expanded on in the :doc:`process`. + +* After the merge window closes, no new features may be added to allow for a + release candidate phase which is intended to fix bugs and regressions. + +*Note:* While we try to adhere to the release schedule, we will +not hesitate and take the liberty to delay a release if there are +good reasons, for example if there are known bugs or other technical +reasons. The code will be released when it is considered ready +without caring too much about the announced deadline. + +*Note 2:* Even though we follow Linux ways in many respects, there are +differences in the actual procedures, which are documented in the +:doc:`process`. + +Version Numbers +--------------- + +Starting with the release in October 2008, the names of the releases were +changed from numerical release numbers without deeper meaning into a time stamp +based numbering. Regular releases are now identified by names consisting of +the calendar year and month of the release date. Additional fields are +frequently used to denote the release candidates. They are also used on rare +occasions to note a bug fix release on top of the previous stable release. + +Examples:: + + U-Boot v2009.11 - Release November 2009 + U-Boot v2009.11.1 - Bug fix release 1 on top of the November 2009 release + U-Boot v2010.09-rc1 - Release candidate 1 for September 2010 release + +Current Status +-------------- + +* U-Boot v2022.07 was released on Mon 11 July 2022. + +* The Merge Window for the next release (v2022.10) is **open** until -rc1 + release on Mon 25 July 2022. + +* Release "v2022.10" is scheduled for 03 Oct 2022. + +Future Releases +--------------- + +..
