Where can I find 0.9 (nightly) documentation

Hi ofx community,
I know lots has changed on 0.9 such as ofRect() replaced by ofDrawRect() and lots of other stuff. Is there a place where the new changes are documented much like:
ofx/documentation ?
I am not looking for the changelog, but the new reference pages. Try as I might I did not find them.

more specific question on the new features in 0.9.0…

I can’t find any example/documentation about ofFpsCounter. I’ve read the class implementation, but I can’t find a way to place in my code.

May you add some examples in the 0.9.1 release?
