Release Plan 2.7.0 (Nov 2020)

Release Dates

KIP Freeze: Sep 30, 2020 (a KIP must be accepted by this date in order to be considered for this release)
Feature Freeze: Oct 7, 2020 (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: Oct 21, 2020
Release: estimated Nov 6, 2020

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 Bill Bejeck

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 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 RCs. Even though only PMC votes are binding, community votes are super important as we evaluate the readiness of the release
