+****************************************************************************
+*                      Platform Specific Changes                           *
+****************************************************************************
+
+Unix
+    * Made the iconv-based QTextCodec class (the "System" codec on
+      Unix systems that support it) stateful. So it's now possible to
+      feed incomplete multibyte sequences to the toUnicode function,
+      as well as the first character in a UTF-16 surrogate pair.
+
+X11
+    * Added a QGtkStyle to integrate with GTK+ based desktop environments.
+    * If font config is used the default font-substitutions will no longer be
+      used instead we rely on fontconfig to determine font substitutions as
+      required.
+    * Improved support for KDE4 desktop settings.
+    * [214071] Improved support for custom freedesktop icon themes.
+    * [195256] Use FreeType's subpixel filtering if available, thus honoring
+      Font Config's LCD filter settings.
+    * Added supported for XFIXES X11 extension for proper clipboard
+      support when non-Qt application owns the clipboard.
+    * Icon support for top level windows (_NET_WM_ICON) was improved
+      to support several icons with different sizes.
+    * [211240] In some cases QFileSystemWatcher didn't notify about
+      files that were moved over another files.
+    * [238743] Added support for the _NET_SYSTEM_TRAY_VISUAL property
+      to use the same visual the system tray manager asks us to use.
+    * [229593] Fix font matching with old fontconfig versions.
+    * [167873] Proper event compression for mouse events when using tablets.
+    * [208181] Fix averageCharWidth to be consistent for y!=x ppem
+    * [229070] Fix QPrintDialog assertion
+    * [211678] Fixed a problem with drawing a QPixmaps on different X11
+      screens.
+    * [221362] Fixed a problem where pixmaps only appeared on the first page
+      in a print preview.
+    * [232666] Fixed a problem with custom page sizes for CUPS printers.
+    * [228770] Fixed a problem that caused the .ps and .pdf filename
+      extensions
+      to not update in the CUPS printer dialog when printing to file.
+    * [230372] Fixed a problem where the number of copies set on a QPrinter
+      object wasn't picked up and updated properly in a QPrintDialog.
+
+Windows
+    * Cleartype rendering was previously supported onto QImages with
+      an ARGB32 channel. For performance reasons, cleartype is now
+      only supported on opaque images using the RGB32 or
+      ARGB32_Premultipled format. Widget and pixmap rendering is
+      unchanged
+    * [175075] Antialiased font rendering quality has been greatly improved
+      by taking gamma correction into account. We should now match the native
+      Windows font rendering better, and the fonts look better in general when
+      drawing fonts on different backgrounds.
+    * [221132] Fixed a problem with System Tray menu visibility.
+    * [221653] Fixed a problem incorrectly causing a Task Bar status change.
+    * [202890] Improved platform consistency with spacing in menus.
+    * [157323] QCombobox now slides to open on relevant platforms.
+    * [237067] Calling showMessage on QSystemTrayIcon with empty arguments
+      now hides the current message.
+    * [145612] Setting an object name for a QThread sets the name that
+      is visible in the debugger for more easy debugging
+      multi-threaded application.
+    * [216664] QLocale now follows the current system locale when the
+      user changes it in the Windows Control Panel.
+    * [223921] Fix writing system detection of TrueType fonts added
+      via a QByteArray in QFontDatabase::addApplicationFont on Windows.
+    * [205455] 'mailto:' links works properly with QDesktopServices::openUrl().
+    * [205516] standardPalette() now returns the system palette for XP and
+      Vista styles.
+    * [207506] Fixed an issue which switches the alignment for input widgets
+      on Vista.
+    * [223951] Added support for VARIANT with IDispatch in ActiveQt.
+    * [224910] Fixed a crash when using the Hierarchy ActiveQt example.
+    * [201223] 'dumpcpp' now prepends the 'classname_' to resolve conflicts.
+    * [198556] QAxServer registering now takes care of '.' before MIME
+      extension.
+    * [223973] Fixed a deadlock in QLocalSocket.

+    * [241901] ActiveQt now supports [out VARIANT*] parameters.
+    * Fix a GDI object leak on the qfileiconprovider.
+    * [200269] Application and systray icons on Windows that had an alpha
+      channel were not drawn correctly.
+    * [239558] Fix a possible crash when reading XPM data containing trigraphs
+      with the Microsoft compilers.
+    * [204440] Fixed a problem with software rendering contexts on Windows,
+      which might have caused rendering errors due to to unresolved extension
+      pointers.
+    * [232263] Fixed a problem with binding textures to a software context
+      under Windows.
+    * [238715] Fixed a problem with alpha-blended cursors under Windows.
+    * [227297] and [232666] Fixed some problems with custom paper
+      sizes under Windows.
+    * [217259] The default printer wasn't correcly detected with some versions
+      of Windows.
+    * [212886] Fixed a problem with network printers not being listed by
+      the QPrinterInfo::availablePrinters() function under Windows.
+    * [205985] Fixed a problem with reusing a QPrinter object to print several
+      jobs with the Microsoft XPS printer driver.
+    * [196281] Fixed QPrinter::setPrintRange() to work under Windows.
+
+Windows CE
+    * Support for QLocalSocket and QLocalServer added.
+    * QtWebKit and Phonon are now supported.
+    * One can mark a widget with the attribute WA_ExpectsKeyboardInput
+      to automatically display / hide the standard input panel on focus
+      events.
+    * [223523] Reimplementations of standard library functions filled the
+      global namespace causing problems when linking statically to other third
+      party libraries using the same attempt.
+    * Support for using OpenSSL with Qt on Windows CE
+
+Mac OS X
+    * Added the macdeployqt tool that simplifies application deployment.
+    * Improved support of widget stylesheet in Mac.
+    * [218980] - Stacking order of windows and dialogs is fixed, such that
+      dialogs always floats above normal windows, even when the dialog is told
+      to behave as a window.
+    * [219844] - A crash that occurred when using the search buttons on a
+      native file dialog is fixed.
+    * [225705] - FileDialog filters not displaying correctly is fixed.
+    * [239155] - Pop-ups will now close when clicking on a window other than
+      the modal window that opened the pop-up.
+    * [210912] - Show event not sent when reshowing a window from minimized
+      state is fixed.
+    * [228017] - QMenu will now close when expanding a system menu.
+    * Added support for Qt to use Cocoa as its backend instead of Carbon. This
+      is primarily for 64-bit applications, but is also available for 32-bit
+      frameworks as well. 32-bit is still Carbon by default. Passing a 64-bit
+      architecture or -cocoa on the command-line will build Qt against Cocoa.
+      Using Cocoa requires Mac OS X 10.5 (or higher) and cannot be used with
+      the -static nor -no-frameworks option. The define QT_MAC_USE_COCOA is
+      available when Qt is built against Cocoa.
+    * Fix a bug that would prevent a window that had been maximized via
+      setMaximized() to go back to normal size when clicking on the window's
+      maximize button.
+    * Added QMacCocoaViewContainer for embedding Cocoa (NSView) controls into
+      a Qt hierarchy. This feature works for either Carbon or Cocoa, but
+      requires Mac OS X 10.5 or greater.
+    * Added QMacNativeWidget for embedding Qt widgets into non-Qt windows
+      (Carbon or Cocoa).
+    * Added MacWindowToolBarButtonHint for controlling whether or not the
+      toolbar button is shown in Qt windows.
+    * QEvents posted via QEventLoop::postEvent() are now treated as a standard
+      event loop source, like timers and normal input events. This means that
+      is should no longer be necessary to run a busy loop to sendPostedEvents()
+      when QApplication is not the main event loop (e.g. when using Qt in a
+      plugin).
+    * [239646] Shortcuts for sub-menu are now disabled when the menu item is
+      disabled.
+    * [241434] Honor the LSBackgroundOnly attribute if it exists in the
+      application's Info.plist.
+    * [239908] More robustness when encountering different types in reading
+      LSUIElement value.
+    * [234742] Add support Qt::XButton1 and Qt::XButton2.
+    * [236203] Much better support for loading multiple Qt's with different
+      namespaces.
+    * Add Qt::AA_MacPluginApplication that allows bypassing some native menu
+      bar initialization that is usually not desired when running Qt in a
+      plugin.
+    * [205297] Applications Dialogs are now marked as application modal in
+      Carbon.
+    * Tooltip base is now set correctly in the application palette.
+    * [222912] [241603] Qt applications no longer reset their palette back to
+      the system palette on every application activate. Only if the values
+      from the system are different from the last time. This should result in
+      custom palette colors/brushes being kept across application activations.
+    * [211758] Fixed a clipping problem when printing multiple pages on a Mac
+      OS X printer.
+    * [212884] Fixed a crash when printing images on Mac OS X.
+    * [219877] Fixed a problem with a QPrinter object not being valid after
+      setting the output format to PDF or PostScript.
+    * [229406] Fixed crash when display mirroring gets enabled.
+    * [189588] Fixed a bug where QColorDialog::getColor(...) always returned a
+      valid color.
+
+Qt for Embedded Linux
+ - Screen drivers
+   * The SVGAlib driver is no longer supported, due to architectural changes.
+   * [235785] Detect VGA16 video mode and warn that it is not supported.
+
+ - Mouse and keyboard drivers
+   * [243374] Fixed bug where PC mouse driver could not be loaded when
+     configured as loadable plugins.
+   * Added Linux Input Subsystem mouse and keypad drivers
+
+ - General fixes
+   * [242922] Run as server by default when compiled with the
+     QT_NO_QWS_MULTIPROCESS macro defined.
+   * Fixed bugs where wrong cursor would be shown in some cases.
+   * Respect min/max size on initial show also for windows without a layout.
+   * Fixed loading of font plugins when QT_NO_FREETYPE is defined.
+   * Autodetect PowerPC in configure.
+   * Add support for precompiled headers.

+****************************************************************************
+*                   Important Behavior Changes                             *
+****************************************************************************
+
+- Event filters
+
+- QFileDialog
+        On Mac, native dialogs are now used when calling show, open, or exec
+        on a QFileDialog, QColorDialog, QPrintDialog, or QFontDialog (i.e not
+        only when using the static functions)
+
+        QFileDialog/QFileSystemModel always return Qt separators ("/")
+        regardless of the platform. It can still handle native separators for
+        Windows. To convert the Qt separators to native separators use
+        QDir::toNativeSeparators().
+
+- QGraphicsTextItem
+        Tab input is send to the document by default, inserting a <tab>
+        character. You can get the old behavior of switching Tab focus by
+        setting setTabChangesFocus(true) (QGraphicsTextItem's Tab handling now
+        behaves identically to QTextEdit and QTextBrowser).
+
+- QGraphicsView
+        QGraphicsView now propagates Qt::Key_Tab and Qt::Key_Backtab to the
+        scene, which sends this to the items. Similar to how QWidget works,
+        this event is caught in QGraphicsItem::sceneEvent() and
+        QGraphicsWidget::event() to handle tab input. Tab input is also
+        proxied to embedded widgets. This allows and item or widget to handle
+        Tab keys (e.g., text input).
+
+- QLocale
+        The locale database was updated to the Unicode CLDR database
+        version 1.6.1
+
+        When the system locale is changed, the LocaleChange event will
+        be sent to all widgets that don't have a locale explicitely
+        set.
+
+- QWebPage
+        Starting with Qt 4.5, the base brush is used for the default
+        background color of the web page. Before, it was the background
+        brush.
+
+- QWidget
+        Font and palette settings assigned to QWidget directly take
+        precedence over application fonts and palettes.
+
+        Focus policies that are set on a widget are now propagated to
+        a focus proxy widget if there is one.
+
+        Windows with fixed size (that are set with QWidget::setFixedSize()
+        function or Qt::MSWindowsFixedSizeDialogHint window hint) might
+        not have a maximize button on the titlebar.
+
+        The behaviour of the window hints was changed to follow the
+        documentation. When the Qt::CustomizeWindowHint is set, the
+        window will not have a titlebar, system menu and titlebar
+        buttons unless the corresponding window hints were explicitely
+        set.
+
+        Setting Qt::WA_PaintOnScreen no longer has any effect on
+        normal widgets. The flag can still be used in conjuction with
+        reimplementing paintEngine() to return 0 so that GDI or
+        DirectX can be used, as previously documented.
