Version 2.1.0

WARNING: The Android Compatibility Library (v4) is now required.

• Added ActionBarSherlock.Activity, ActionBarSherlock.FragmentActivity,
  and ActionBarSherlock.ListActivity for extension by implementing
  activities, the latter of which is deprecated. This affords a much tighter
  integration and allows for the use of other new features listed below.
• New API method: layout(Fragment) will use the fragment argument as the
  content to the activity.
• New API method: menu(int) allows for the inflation of menu XMLs from a
  resource. For the non-native implementation, the XML can be inflated to a
  custom Menu which can then be applied appropriately to the third-party
  action bar. Sub-menus are also supported. Third-party action bar handlers
  should implement ActionBarSherlock.HasMenu for this functionality. This
  feature requires that activities extend from one of the provided activity
  base classes.
• New API method: homeAsUp(boolean). This mimics the native method
  setDisplayHomeAsUpEnalbed on the native action bar. Third-party action bar
  handlers should implement ActionBarSherlock.HasHomeAsUp for this
  functionality.
• New API method: useLogo(boolean) will trigger the action bar to hide the
  application icon/home button and title and show a larger logo representing
  the application. Third-party action bar handlers should implement
  ActionBarSherlock.HasLogo for this functionality.
• New API method: listNavigation(SpinnerAdapter, OnNavigationListener). Tells
  the action bar to use drop-down style navigation with the specified list of
  items and callback listener. Third-party action bar handlers should
  implement ActionBarSherlock.HasListNavigation for this functionality.
• Javadocs are now available at
  jakewharton.github.com/ActionBarSherlock.
• A standalone JAR is now available via the
  GitHub downloads page
  or in my
  personal maven repository
  as com.jakewharton:android-actionbarsherlock:2.1.0.
