Version 3.3.0

• Tabs are now displayed below the action bar on all medium-screen devices and
  portrait large-screen devices.
• Fix: Dialog fragments no longer throw an IllegalStateException when being
  used as a regular fragment (i.e., not as a popup). See
  StackOverflow
  for more information.
• Fix: Popping a fragment off of the back stack now properly assigns its parent
  activity.
• Fix: An activity result no longer causes a NullPointerException when the
  target fragment no longer exists.
• Fix: Action item dividers are now properly initially hidden when their
  associated action items are as well.
