I'm a bit confused about the available versions of action streams.
The plugin directory still shows AS 1.0 as the current version.
I've seen a blog post that mentions that MT 4.25 (Motion) ships with AS 1.1. I've seen other mentions of AS 1.1 around the forums (Here, for example, refers to an upgrade from AS 1.1 to AS 2.0).
has long had an AS 2.0 beta available. Oddly, the Read Me for the AS 2.0 beta makes no mention of AS 1.1.
So, does motion ship with AS 1.1? If so, is that the 2.0 beta? If not, where does 2.0 fit now? The order seems to be 1.0, 2.0b, 1.1, which of courrse doesn't make any sense at all.
A reply here would help clear up the confusions, but the plugin page really needs to be updated or something more official and visible than the hodge-podge we have now.
Reported on Movable Type 4.2

Action Streams 2.1 and Community Action Streams 1.2 ship with MT 4.25. The AS 2.0 beta has been available for a while, some have made zips of it, others have grabbed it from SVN.
I am not sure why it is not in the plugin directory yet.

Thanks Ken, that clears things up considerably. Hopefully, this will get cleared up officially and more visibly soon.
BTW - In case you didn't catch it, it was your blog post, Ken, that indicated to me that Motion shipped with AS 1.1.

Gah. Simple typo. Fixed.
Once I learned what was going on, I figured it was a typo. Threw me at first though. :-D
