So I fully upgraded my project to 2.0 at last.
It would have been much easier with a 1.6->2.0 changelog, but I understand that 2.0 is still undergoing development.
Still, I eagerly await such a changelog as an addition to the site, as it would be extremely helpful to all developers who wish to do what I did.
Thanks for the quick reply also btw Laurent, the SVN log provided useful.
