About Experimental

For Unity experimental releases:

  • Expect breaking API changes - using this early has risks! See release notes for extensive information and links to additional content.
  • Expect no SLA on timeline to ship patches and fixes to releases, as we are still establishing our test and release cadence.
  • Expect these releases to move towards a fuller Release.
  • Expect us to answer questions for early adopters on Discord and Forums. We welcome all feedback and issues logged!
