Release Dates

  • KIP Freeze: Jan 22, 2020 (a KIP must be accepted by this date in order to be considered for this release)
  • Feature Freeze: Jan 29, 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: Feb 12, 2020
  • Release: Feb 26, 2020  TBD


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 David Arthur.
