Version 3.4.2

• Fix: Stacked action bar now properly sets the tab bar background based on
  the theme.

Version 3.4.1

• The makeFragmentName method in FragmentPagerAdapter has been changed to
  public scope to allow for easier access to your fragments that it is
  managing.
• Action bar will now animate when calling show() or hide().
• SherlockPreferenceActivity now provides full fragment and loader support.
• Examples for the plugins are now in their own sample application.
• Fix: Home icon no longer erroneously clipped when it exceeds the size of the
  action bar.
• Fix: Tabs will now scroll horizontally to mimic the native action bar
  behavior.
• Fix: Plugins now properly DO NOT inline their R.java integer constants.
• Fix: Tabs below the action bar are now styled with a default background so
  that they do not incorrectly inherit an applied background unless explicity
  declared.

Version 3.4.0

• Library now uses the r4 version of the compatibility library for its base.
  Ice Cream Sandwich-specific implementations are currently disabled, however,
  but will be added in a future version of the library.
• Context menu callbacks now use the support version of MenuItem to maintain
  consistency.
• Added preference plugin which provides an action bar enhanced preference
  screen.
• Fix: abHomeLayout theme attribute is now honored.
• Fix: onPrepareOptionsMenu is now properly dispatched upon menu
  invalidation.

Version 3.3.1

ADT 14 is now required. Maven 3 is required if building from the command line.

• XML-defined onClick attributes will now check for an onClick method that
  takes an android.support.v4.view.MenuItem instance.
• Tabs on medium screens in landscape now display inline rather than below the
  action bar to mirror how Android 4.0 behaves with the same configuration.
• Fix: Menu inflater properly checks activity context for onClick method
  declared in the XML.
• Fix: Dialog fragment properly saves its showDialog state when not being
  used as a popup.
• Fix: Return -1 when in tab navigation but no tab is selected. This brings
  the library in line with the post-3.0 behavior.
• Fix: Removing a menu group no longer throws an IndexOutOfBoundsException.
• Fix: getSelectedTab and getTabAt no longer throw NullPointerExceptions
  on post-3.0 when no tab was selected or no tab existed at the specified
  position, respectively.
• Fix: findFragmentById now properly returns fragments attached to
  android.R.id.content when run on pre-3.0 devices.

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.

Version 3.2.3

• Fix: Fragments in a ViewPager that contributed items to the options menu
  were caught in a race condition causing inconsistent results when a new page
  was selected. This regression was introduced in version 3.2.2.

Version 3.2.2

• Fix: Side-effects related to using FragmentMapActivity due to how it was
  referencing resources from the main library.
• Fix: Fragments adjacent to the currently selected fragment in a ViewPager
  no longer receive context menu events.
• Fix: Eliminate exception when inflating context menus on 3.0+ when using
  getMenuInflater().
• Fix: ViewPager now determines whether or not an activity menu invalidation
  is required independently of whether or not fragments were created or
  destroyed. This should fix an edge case where an activity with a ViewPager
  containing only two fragments would not get its menu properly invalidated.

Version 3.2.1

• Fix: Action mode API incorrectly using the native Menu and MenuItem
  classes causing an easy pitfall for ClassCastExceptions.
• Fix: Large action bar backgrounds increasing the size beyond that alloted in
  the theme.

Version 3.2.0

• Added support for MapView and the Google APIs through the use of
  FragmentMapActivity. If you are using a map within a fragment you must
  ensure it is always attached to an activity which extends from this new base
  class.

Since supporting maps requires compiling against the Google APIs, this
functionality is implemented in the form of a plugin which is to be used
alongside the normal library. You can choose to add it as an additional
library project or by including it as a .jar. Maven users may simply
include the additional dependency (artifactId: plugin-maps).

• Fix: Fragments adjacent to the currently selected fragment in a ViewPager
  no longer contribute to the activity menu.
• ActionBar.Tab has been changed from an interface to an abstract class to
  mirror its native counterpart.

Version 3.1.3

• Renamed all resources to be prefixed with abs__ to avoid conflicts when
  including in your project.
• Fix: Action bar background being set on two views causing artifacts to remain
  on screen when the action bar was hidden.
• Fix: Incorrect sub-menu item being selected by default when the sub-menu was
  triggered from the native options menu on pre-3.0.
• Fix: MenuItem.setVisible now properly updates the associated action item and
  native menu item visible state.
• Fix: Adding items to a menu now honors its ordering and category.
• Fix: Fragment options item selected callback now uses the proper version of
  MenuItem.
