I just found this thread after math-related things stopped working. I have two use cases that don't work now:
1. Inserting a dollar pair $$ using `cdlatex-dollar` (it thinks we're inside a math environment). 2. Inserting of cdlatex environments using their built-in completions, e.g. ali<TAB> eqn<TAB> stopped working. Previously org-cdlatex worked perfectly, you could insert \alpha using `a and it compiled to HTML/latex (without $$), have $...$ compiled into an inline equation and insert latex environment like \begin{align}...\end{align} without explicit math environment and was also compiled perfectly to HTML/latex. -- Daniel Fleischer
