    - Added ExploreByTouchHelper [5] to simplify the implementation of accessibility for custom views.
    - Fixed a problem with ViewPager [2] incorrectly populating TYPE_VIEW_SCROLLED [6] accessibility events.
    - Fixed a null pointer exception in ViewPager [2] when populating an accessibility event.
    - Simplified AccessibilityNodeInfoCompat [7] by changing CharSequence [8] inputs to String [9] objects.

    - Added WakefulBroadcastReceiver [14] helper class for implementing
      a common pattern of detecting a device wakeup event and passing work off to a Service [15] while ensuring that the device does not go back to sleep before the handoff is complete.
    - Added two new APIs, commitContentChanged() [16] and rollbackContentChanged() [17], to AsyncTaskLoader [18] to help deal with background updates for data changes that are subsequently canceled.

New v7 appcompat library:
  - Added ActionBar [19] to allow implementation of the action bar user interface design pattern [20] back to Android 2.1 (API level 7) and higher. Use of this class requires that you implement your activity by extending the new ActionBarActivity [21] class.
