 - [QTBUG-9351] Fixed a bug that caused modified headerview-properties
   of item views to be duplicated in the UI-file.
 - [QTBUG-8347] Fixed a layout problem caused by embedded images in the rich
   text of a QLabel.
 - [QTBUG-8041], [QTBUG-8213] Fixed a crash related to undo while moving
   widgets by arrow keys.
 - [QTBUG-7822] Added support for the 'windowOpacity'-property.
 - [QTBUG-7764] Fixed the emission of the propertyChanged()-signal of
   QDesignerPropertyEditorInterface.
 - [QTBUG-5492] Made widgetbox-filter match on class names, too.

- Linguist
  * The GNU gettext PO format support has been improved

- rcc


- moc
  * Fixed several parsing bugs. Including changes in the normalized signature.

- uic

- uic3

 - [QTBUG-9207] Fixed export of image files of type XPM, added
   compatibility option -limit-xpm-linelength.

- qmake
  * Removed remainder of tmake compatibility
  * Removed remainder of mac9 mode
  * Removed MSVC6 generator
  * Removed makespecs for MSVC.NET and MSVC2002
  * Deprecated -win32/-unix/-macx options, following various cleanups
    relating to platform support. Cross-building makespecs should now
    specify a TARGET_PLATFORM.
  * Started to warn about use of various constructs:
    - non-lowercased replace $$function() calls
    - deprecated variables
    - unescaped backslashes.
      NOTE: You should use UNIX path separators where possible. qmake
      will warn about unnecessary Windows path separators in the future.
  * Removed expansion of qmake- & environment variables in some unexpected
    cases (double expansions, command line options, etc.)
  * Removed splitting at semicolons of literal values which were assigned
    directly to INCLUDEPATH and DEPENDPATH
  * Removed UNIX-specific exporting of all qmake variables to the environment
    of subprocesses invoked via system(). You should put specific assignments
    into the invoked shell command instead.
  * Started to short-cut evaluation inside if() tests, consistently with
    evaluation outside if().
  * Added possibility to request project recursion from within a PRO file

QtScript: Changes due to updating src/3rdparty/javascriptcore:
 - It is no longer possible to delete an undeletable property from C++
   using QScriptValue::setProperty().
 - The QScriptEngineAgent::positionChange() callback will always report
   a column number of 1.
 - QScriptValueIterator will include the "length" property when iterating
   over Array objects.

QtCore:
  - QChar no longer carries the Q_PACKED tag on ARM. This flag was
    used to allow proper alignment of QChar on 2 bytes on older ARM
    ABIs, but it also allowed for unaligned access. Qt never generates
    or uses unaligned access and the new EABI aligns as expected, so
    the flag was removed.
  - QTextBoundaryFinder is now consistent with ICU when it comes to
    line breaking, reporting the index of the boundary at which the line
    break should occur rather than the index of the character.

QtGui:
  - QWidget::setLayoutDirection no longer affects the text layout
    direction (Qt::LeftToRight or Qt::RightToLeft) of QTextEdit, QLineEdit
    and widgets based on them. The default text layout direction
    (Qt::LayoutDirectionAuto) is now detected from keyboard layout and
    language of the text (conforms to Unicode standards). To
    programmatically force the text direction of a QTextEdit, you can
    change the defaultTextOption of the QTextDocument associated with that
    widget with a new QTextOption of different textDirection property. For
    QLineEdit, the only way so far is sending a Qt::Key_Direction_L/R
    keyboard event to that widget.

QtNetwork:
  - Qt does no longer provide its own CA bundle, but uses system APIs for
    retrieving the default system certificates.
