It might be a change to texmathp.el. It is part of Auctex and checks if
math mode is on or off. I could not find align environment in the list
of default environments. Maybe that has changed.

However, I added align and align* to "Texmathp Tex Commands" from the
customize browser (open a .tex file to customize auctex). Tab-expansion
is working now. Can anyone confirm?

In my .emacs, it added to custom-set-variables:
'(texmathp-tex-commands (quote (("align*" env-on) ("align" env-on))))
