2.0b1?

Yes, what changed?

2.0b1 – as in “beta”??? Is this a half baked “upgrade”, like the recent previous ones?

Beta releases are not “half baked.” They are released early for developers and users who are interested in testing new features early. There are often bugs in beta releases, and they need to be reported and addressed.

A new stable version of Jetpack has been released anyway though! Version 2.0 is out. You can see the announcement here:
