Hello,
It's officially still alpha, but we're very close to making it BETA.
Right now, the next step is to for us to finish up a few minor features in DA so that we can release 1.42.0 as beta (release candidate).
Once 1.42.0 is out, then CB 2.0 will "officially" be BETA.
We hope to release DA 1.42.0 RC1 (eg: BETA) within a few weeks, then in full a few weeks after that (when CB 2.0 is "officially" BETA)
In reality, there isn't really anything left to do with CB 2.0, so if you grab the current pre-release DA binaries, it will essentially be the same thing.
However, the purpose of testing is to find any issues that we have not yet found (hopefully there are none), which is why we cannot yet officially recommend using it on a production system.
John
