I can't find the
/stats method in the new usage documentation.
A quick run of
http://api.stackoverflow.com/1.1/stats reveals that the method is still there. However, it is not documented.
Woops, missed that one.
Returning "1.0" for the API version is status-bydesign, for compatibility purposes.
It was a mistake to even add that field (made sense in the beta, makes no sense with a released API), consider it deprecated.
