I would like to have version-centric "copies" of the ORM documentation page (http://hibernate.org/orm/documentation/). Currently when you go to that page some of the data is "version aware", some of it is not.
I think ideally we'd have the landing page represent the current production release. From there, we'd have ways to get to older versions and maybe even the newer development versions. This would entail a url scheme like:
http://hibernate.org/orm/documentation/current (alias for current production release - e.g. 4.3 atm)
