This behaviour is due to this change in beamer.el[1]. AUCTeX now checks if users have auto-filling enabled before filling. Hence, you have to turn that mode on in order to get the old behaviour with something like this in your init file: (add-hook 'LaTeX-mode-hook #'turn-on-auto-fill) Best, Arash Footnotes: [1] http://git.savannah.gnu.org/cgit/auctex.git/commit/style/beamer.el?id=a21c10a076734b710145df5950459351025b8723
