Non-Final releases are the best way to test drive new features and APIs to provide feedback before we lock down the API with a Final release. We welcome such feedback in our forum.
An Alpha can be unstable. A Beta should work (it passes automated testing), but its new APIs might still change in the next release. A CR should be almost identical to the Final release.
There is no Alpha or Beta yet because we just released a Final version.
Nightly snapshots are unstable binaries, built automatically by our CI server.
For older community releases, check the release archive.
