NHibernate 2.0 is not even close to release, but it is shaping up nicely. Oren Eini (His blog is called Ayende @ Rahien) has a list of interesting new features . Dario Quintana has something to say as well . He has contributed some code to the uNHAddins for Active Record Detached Query support . The Castle development team is considering pointing to NHibernate Trunk (which will be released as 2.0 eventually) so they/we can take advantage of the new features. If Castle Active Record uses NHibernate trunk, I would advise you to be diligent wit! your test code, and don't forget to run the Castle test code too. You can track Castle Project changes on FishEye .
