THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Release Dates
- KIP Freeze: TBD (A KIP must be accepted by this date in order to be considered for this release. Note, any KIP that may not be implemented in a week, or that might destabilize the release, should be deferred.)
- Feature Freeze: TBD (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: TBD
- At least two weeks of stabilization will follow Code Freeze.
