This is caused by this commit, which changes how org-split-string works. f776e65373fa135fffb51e201698823fbfb3865b Before (org-split-string "" ",") would return ‘nil’. Now it returns "". Depending on whether the new behavior is desired or not, the fix should either be in ‘org-split-string’ or in ‘org-beamer--format-frame’. I’ll wait for Nicolas’ verdict. For now, if necessary, you can hot-patch the function in ox-beamer.el to something like, (options (cl-remove-if-not 'org-string-nw-p (append ...))) Rasmus -- Vote for proprietary math!
