From today’s Emacs 24.4 announcement:

Highlights of this release include:
  - A built-in web browser (M-x eww)
  - Improved multi-monitor and fullscreen support
  - "Electric" indentation is enabled by default
  - Support for saving and restoring the state of frames and windows
  - Emacs Lisp packages can now be digitally signed
  - A new "advice" mechanism for Emacs Lisp
  - File notification support
  - Pixel-based resizing for frames and windows
  - Support for menus in text terminals
  - A new rectangular mark mode (C-x SPC)

Looks like I’ll need to add a few more disabling commands to my .emacs file…
