[keycloak-user] Updated release cadence

As we've started working in 3 week sprints we are considering a new release model for Keycloak. What we are considering is doing a Beta release for every sprint, then for every 4th sprint (each quarter) we plan to do a Final release. For a beta release existing features will be considered stable, while new features may not be ready for prime time. The recommendation will still be to upgrade to always update to the latest release to receive the latest security fixes and other fixes. However, care should be taken before using new features in production until a Final release is available. Thoughts?
