Hi
When you want to change the beamer class options, you needed to add
#+LATEX_CLASS: beamer
#+LATEX_CLASS_OPTIONS: ...
With this simple patch, you can declare them directly as
#+BEAMER_CLASS_OPTIONS:...
which is more consistent with using
#+STARTUP: beamer
and the LaTeX settings.
Best, /PA

Subject: [PATCH] New BEAMER_CLASS_OPTIONS
* lisp/ox-beamer.el: Create :beamer-class-options. This avoids having
to declare the LATEX_CLASS explicitly as beamer.
(org-beamer-template): replace the default `[presentation]' option to
the new options if :beamer-class-options have been defined.
* doc/org-manual.org: add ~#+BEAMER_CLASS_OPTIONS:~ to the beamer
class documentation
* etc/ORG_NEWS: Announce new ~#+BEAMER_CLASS_OPTIONS:~
