Indeed, we have restructured quite a lot in font-latex.el in the last
ELPA release, and now font-latex-extend-region-functions is gone.
However, there is no font-latex-extend-region-backwards-lemma-envII in
AUCTeX.  Do you use some extension package providing that function?  Or
is that in your ~/.emacs?

Bye,
