Thanks for the PR!

Please

1. Change the @since version number for twentyeleven_theme_options_help() (added in r19237).
2. Add a @since note for twentyeleven_option_page_capability(). r17987 created the function, and WordPress 3.2 bundled Twenty Eleven 1.1.
   * @since Twenty Eleven 1.1

My suggestions for Twenty_Eleven_Ephemera_Widget::update() are more questionable.

[huzaifaalmesbah]

Thanks for the detailed review and version history notes @sabernhardt I’ve updated the @SInCE tags accordingly and reviewed your suggestions for Twenty_Eleven_Ephemera_Widget::update(). Really appreciate your guidance!
