+  * Use ActiveRecord 2.1's dirty attribute checking instead [Asa Calow]
+  * Remove last traces of #non_versioned_fields
+  * Remove AR::Base.find_version and AR::Base.find_versions, rely on AR association proxies and named_scope

 * (5 Oct 2006) Allow customization of #versions association options [Dan Peterson]
