Ok... Abdera2 is pretty much stable. I would like to see if we can cut a release candidate. There's some additional documentation that needs to be written up and I'm sure there's a lot more testing that can be done, but things are looking pretty solid right now.
Note: all of the server side code has been extracted into a separate project that needs a lot more work. The Abdera2 Release Candidate would ONLY contain the Atom and Activity Streams data format and client side code. Here's my +1. - James
