• KIP Freeze: Sep 25, 2019 (a KIP must be accepted by this date in order to be considered for this release)
• Feature Freeze: Oct 4, 2019 (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 16, 2019
• Release: Oct 30, 2019Dec 16

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.
