Release Dates
(all are in 2023)
- KIP Freeze: 18th November (Saturday)
- A KIP must be accepted by this date in order to be considered for this release. Note, any KIP that may not be implemented in a week, or that might destabilize the release, should be deferred.
- Feature Freeze: 8th December (Friday)
- major features merged & working on stabilisation, minor features have PR, release branch cut; anything not in this state will be automatically moved to the next release in JIRA
- Code Freeze: 20th December (Wednesday)
- At least two weeks of stabilization will follow Code Freeze, meaning we expect to release no earlier than January 3rd. We will move as fast as we can, and aim completion the earliest we can in January.
These dates are goals and subject to change, but we expect to stay on the Time Based Release Plan unless unexpected critical issues come up. While the earliest possible release date is 2w after code freeze, release candidates (RCs) will roll out as needed until the release vote passes.
The release manager is Stanislav Kozlovski
How to Contribute
Before code freeze:
- Participate in votes and discussions to land or postpone the open KIPs.
- Review patches. We anticipate that this release, as it usually happens, will be bottlenecked mostly on reviews. The more reviewers, the more content we can fit in.
- Write unit/integration/system tests. We want to preserve the tradition of high-quality releases in Apache Kafka.
After code freeze:
- Write more unit/integration/system tests. We want to preserve the tradition of high-quality releases in Apache Kafka.
- Improve documentation.
- Test the release candidates.
- Open blocker JIRAs on critical issues found. Open non-blocker JIRAs on any other issues found.
- Fix critical bugs.
- Review bug fixes.
- Vote on release candidates. Even though only PMC votes are binding, community votes are super important as we evaluate the readiness of the release.
- Ensure that release candidates include artifacts for the new Connect test-plugins module (see )
Open Issues
