Over a year ago I became disinterested enough in NQA that I decided to deprecate it.

In a true Open Source tradition, Hudson Akridge, Robert Dusek and Ricardo Borges stepped in and took ownership of the project.

You can find the new project at this location:

They already have a new version out for the current version of NHibernate.
