Release Dates
- KIP Freeze: TBD
- Feature Freeze: TBD
- Code Freeze: TBD
- Release: JTBD
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 target release date is fixed at ~2w after code freeze, RCs will roll out as needed until the release vote passes.
The release manager is Guozhang Wang.
Release Features
This is a list of key features/improvements/bugfixes that we can include with release notes (WIP):
- Drop support of Java 7 (KIP-118)
- JBOD support for disk failures (KIP-112)
- Kafka Streams API improvements (KIP-120 / 130 / 138 / 150 / 160 / 161), and drop compatibility "Evolving" annotations
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 will be bottlenecked mostly on reviews. The more reviewers, the more content we can fit in.
- Write system tests. We want to preserve the tradition of high-quality releases in Apache Kafka.
After code freeze:
- Test the release candidates
- Open bugs on important issues found
- Fix bugs
- Review bug fixes
- Vote on RCs. Even though only PMC votes are binding, community votes are super important as we evaluate the readiness of the release
