Yoga Release Schedule
Note
Deadlines are generally the Thursday of the week on which they are noted below. Exceptions to this policy will be explicitly mentioned in the event description.
06 October 2021 - 30 March 2022 (25 weeks)
Cross-project events
Yoga Goals Research
Pre-cycle planning and investigation into the community-wide goals for Yoga.
Virtual PTG
A virtual PTG will be held during this week (October 18-22, 2021). The Project Teams Gathering provides and opportunity for teams to collaborate and plan, and discuss requirements for future releases.
Yoga-1 milestone
18 November, 2021 is the Yoga-1 milestone. See project-specific notes for relevant deadlines.
Yoga Cycle-Trailing Release Deadline
All projects following the cycle-trailing release model must release their Xena deliverables by 16 December, 2021.
Yoga-2 milestone
06 January, 2022 is the Yoga-2 milestone. See project-specific notes for relevant deadlines.
Membership Freeze
Projects must participate in at least two milestones in order to be considered part of the release. Projects made official after the second milestone, or which fail to produce milestone releases for at least one of the first and second milestones as well as the third milestone, are therefore not considered part of the release for the cycle. This does not apply to cycle-trailing packaging / lifecycle management projects.
Extra-ATC freeze
All contributions to OpenStack are valuable, but some are not expressed as Gerrit code changes. That allow teams to list active contributors to their projects and who do not have a code contribution this cycle, and therefore won't automatically be considered an Active Technical Contributor and allowed to vote. This is done by adding extra-atcs to https://opendev.org/openstack/governance/src/branch/master/reference/projects.yaml before the Extra-ATC freeze on 10 February, 2022.
Final release for non-client libraries
Libraries that are not client libraries (Oslo and others) should issue their final release during this week. That allows to give time for last-minute changes before feature freeze.
Yoga-3 milestone
24 February, 2022 is the Yoga-3 milestone. See project-specific notes for relevant deadlines.
Feature freeze
The Yoga-3 milestone marks feature freeze for projects following the release:cycle-with-rc model. No featureful patch should be landed after this point. Exceptions may be granted by the project PTL.
Final release for client libraries
Client libraries should issue their final release during this week, to match feature freeze.
Soft StringFreeze
You are no longer allowed to accept proposed changes containing modifications in user-facing strings. Such changes should be rejected by the review team and postponed until the next series development opens (which should happen when RC1 is published).
Requirements freeze
After the Yoga-3 milestone, only critical requirements and constraints changes will be allowed. Freezing our requirements list gives packagers downstream an opportunity to catch up and prepare packages for everything necessary for distributions of the upcoming release. The requirements remain frozen until the stable branches are created, with the release candidates.
Yoga Community Goals Completed
Teams should prepare their documentation for completing the community-wide goals for Yoga.
RC1 target week
The week of 07 March, 2022 is the target date for projects following the release:cycle-with-rc model to issue their first release candidate.
Hard StringFreeze
This happens when the RC1 for the project is tagged. At this point, ideally no strings are changed (or added, or removed), to give translators time to finish up their efforts.
Final RCs and intermediary releases
The week of 21st-25th March, 2022 is the last week to issue release candidates or intermediary releases before release week. During release week, only final-release-critical releases will be accepted (at the discretion of the release team).
Yoga release
The Yoga coordinated release will happen on Wednesday, 30 March, 2022.
Open Infrastructure Summit
The Open Infrastructure Summit is expected to take place some time in October. Exact event dates are yet to be determined.
Cycle Highlights
Cycle highlights need to be added to the release deliverables by feature freeze to be included in any marketing release messaging. Highlights may be added after this point, but they will likely only be useful for historical purposes.
See the Project Team Guide for more details and instructions on adding these highlights.
For examples of previous release highlights: Stein Highlights, Train Highlights, Ussuri Highlights, Victoria Highlights. Wallaby Highlights. Xena Highlights.
Project-specific events
Cinder
Cinder Spec Freeze
All Cinder Specs for features to be implemented in Yoga must be approved by Friday 17 December 2021 (23:59 UTC).
Cinder New Driver Merge Deadline
The deadline for merging a new backend driver to Cinder for the Yoga release is Friday 21 January 2022 (20:00 UTC). New drivers must be (a) code complete including unit tests, (b) merged into the code repository, and (c) must have a 3rd Party CI running reliably. (Note that because of where some holidays fall this cycle, this is later than the usual Milestone-2 deadline.)
Cinder New Target Driver Merge Deadline
The deadline for merging a new target driver to Cinder for the Yoga release is Friday 21 January 2022 (20:00 UTC). New target drivers must be (a) code complete including unit tests, (b) merged into the code repository, and (c) must have a 3rd Party CI running reliably.
Cinder New Feature Status Checkpoint
If your new Cinder feature requires client support, keep in mind that the final release for client libraries is in four weeks. Thus your Cinder feature should be substantially complete with unit tests by this time so that any client changes can be reviewed, tested, and merged before 24 February 2022.
Cinder Driver Features Declaration
New features added to Cinder drivers must be merged at the time of the OpenStack-wide Feature Freeze, which is coming up in three weeks. Before the Cinder meeting this week, you should post a blueprint in Launchpad listing the Gerrit reviews of features you'd like to land in Yoga. (You can look among the Wallaby and Xena blueprints for examples; contact the PTL if you have any questions.) This will help the team prioritize reviews and give you candid early feedback on whether the features look ready.
Cinder os-brick Yoga Release
Changes to be included in the Yoga release of the os-brick library must be merged by Thursday 10 February 2022 (20:00 UTC).
Cinder 3rd Party CI Compliance Checkpoint
This is a reminder that in order for a Cinder driver to be considered 'supported' in the Yoga release, its third party CI must be running properly when the Cinder team does a final compliance check around the time of the third milestone. See the Driver Compliance section of the Cinder Documentation for details.
Oslo
Oslo Feature Freeze
All new Oslo features must be proposed and substantially complete, with unit tests by the end of the week.
Manila
Manila Spec Freeze
All Manila specs targeted to Yoga must be approved by the end of the week.
Manila New Driver Deadline
By the end of the week all new backend drivers for Manila must be substantially complete, with unit tests, and passing 3rd party CI. Drivers do not have to actually merge until feature freeze.
Manila Feature Proposal Freeze
All new Manila features must be proposed and substantially completed, with unit, functional and integration tests by the end of the week.
