* Source incompatible changes *
****************************************************************************
+- QAtomicInt's and QAtomicPointer's non-atomic convenience methods
+ (i.e., operator=, operator int / operator T*, operator!, operator==,
+ operator!= and operator->) have been removed as they did implicit
+ loads and stores of unspecified memory ordering. Code dealing with
+ is expected to use load(), loadAquire(), store() and storeRelease()
+ as necessary instead.
- QObject
* The signatures of the connectNotify() and disconnectNotify() functions
in Qt4, so these methods return a bool now. If your code used the undocumented
QBool, simply replace it with bool.
+- The old macros TRUE and FALSE have been removed, use true and false instead.
+
- qIsDetached<> has been removed without replacement.
- The return type of QFlags<Enum>::operator int() now matches the Enum's underlying
or use static_cast<int>(Qt::SolidLine) to create a QVariant of type int with
the same value as the enum.
+- QLocale:
+ * The historical language and country names were updated to their modern values,
+ some deprecated names were dropped or mapped to their modern alternatives.
+
- QTestLib:
* The plain-text, xml and lightxml test output formats have been changed to
show a test result for every row of test data in data-driven tests. In
- QPrintEngine - Removed the PPK_SuppressSystemPrintStatus key as no longer used.
+- QCoreApplication::Type and QApplication::type() have been removed. These
+ Qt3 legacy application types did not match the application types
+ available in Qt5. Use for example qobject_cast instead to dynamically
+ find out the exact application type.
+
+- The following QStyle implementations have been made internal:
+ * QFusionStyle
+ * QGtkStyle
+ * QMacStyle
+ * QWindowsCEStyle
+ * QWindowsMobileStyle
+ * QWindowsStyle
+ * QWindowsVistaStyle
+ * QWindowsXPStyle
+ Instead of creating instances or inheriting these classes directly, use:
+ * QStyleFactory for creating instances of specific styles
+ * QProxyStyle for customizing existing style implementations
+ * QCommonStyle as a base for implementing full custom styles.

- Qt::WindowSoftkeysVisibleHint
- Qt::WindowSoftkeysRespondHint
+* QLocale
+ - [QTBUG-27987] Constructing a QLocale object with the short locale id has been improved.
+
+* QObject
+ - Added overloads of connect() to connect using pointers to member function
+ - Added QObject::isSignalConnected()

-----
* Accessibility has been refactored. The hierachy of accessible objects is implemented via
by QAbstractProxyModel and related classes. A copy of QProxyModel is available
in the UiHelpers library.
+* The virtual methods QApplication::commitData and QApplication::saveState, used for session
+ management, no longer exist.
+ Connect to the commitDataRequest and saveStateRequest signals instead.
+ The new isSessionSaving() method can be used in the cases where the closeEvent of your
+ window needs to know whether it is being called during shutdown.
+
* [QTBUG-20503] QFileSystemModel no longer masks out write permissions from the permissions
returned from permissions() or data(FilePermissions), even if in read-only mode
(QFileSystemModel::isReadOnly()).
* The default major version of QGLFormat has been changed to 2 to be aligned
with QSurfaceFormat. Applications that want to use a different version should
explicitly request it using QGLFormat::setVersion().
+* void QGLContext::generateFontDisplayLists(const QFont& font, int listBase)
+ and int QGLWidget::fontDisplayListBase(const QFont & fnt, int listBase)
+ which were deprecated in Qt 4 have been removed.
+* Previously deprecated default value listBase parameter has been removed from
+ both QGLWidget::renderText() functions.
+* In order to ensure support on more platforms, stricter requirements have been
+ introduced for doing threaded OpenGL. First, you must call makeCurrent() at
+ least once per swapBuffers() call, so that the platform has a chance to
+ synchronize resizes to the OpenGL surface. Second, before doing makeCurrent()
+ or swapBuffers() in a separate thread, you must call
+ QGLContext::moveToThread(QThread *) to explicitly let Qt know in which thread
+ a QGLContext is currently being used. You also need to make sure that the
+ context is not current in the current thread before moving it to a different
+ thread.

* [QTBUG-20785] The moc now has a -b<file> option to #include an additional
file at the beginning of the generated file.
-
+* moc is now able to fully understand and expands preprocessor macros.
