Release Dates
- Feature Freeze: Jan 13, 2017 (major features merged & working on stabilization, minor features have PR, release branch cut; anything not in this state will be automatically moved to the next release in JIRA)
- Code Freeze: Jan 27, 2017 (first RC created now)
- Release: Feb 14, 2017 ♥
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.
Release Manager
The release manager is Ewen Cheslack-Postava
Release Features
This is a list of key features/improvements/bugfixes that we can include with release notes:
- Session windows in Kafka Streams (KIP-94)
- Improved compatibility for Java clients (compatible with older brokers in addition to brokers supporting older client versions, KIP-94)
- Dynamic JAAS configuration – multiple client auth per process, KIP-85
- More intuitive Kafka Streams join semantics (KIP-77)
- Avoid flushing pipeline in sink connectors (KIP-89)
How to Contribute
Before Jan 27:
- 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 Jan 27:
- 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
