 QtCore
 ------
 
+ - Added QCollator, a class to collate Unicode strings.
+ - Added QCommandLineParser, a class to parse command lines.
+ - Added QFileSelector, a class to select platform-specific file assets.
+ - Added QLoggingCategory and related functions for logging
+ - [QTBUG-23946] Fixed a bug that prevented Qt from being built in a
+   namespace on Mac OS X.
+ - Updated the locale database to CLDR 23.1
+ - Added support for ARMv8 64-bit mode.
+
+ - Metatype system (QMetaType & QVariant):
+   * Qt now handles metatypes automatically for std::vector, std::list,
+     std::pair and std::map
+   * The metatype system now supports registering explicit conversion
+     functions via QMetaType::registerConverter
+   * The metatype system now supports iteration over a container type via
+     QSequentialIterable and QAssociativeIterable
+   * Registering the same type name twice will now print only a warning (as
+     opposed to aborting the execution of the program)
+
+ - Qt Containers:
+   * In debug mode, the Qt containers will now verify whether the iterators
+     passed to most mutating functions belong to the iterator in question.
+   * Fixed a number of bugs that would modify shared containers when calling
+     erase(), under corner-case conditions.
+
 - QtAlgorithms
   With STL no longer being optional for building and using Qt, a number of parts
   of QtAlgorithms no longer make sense, and have therefore been deprecated.

  - QJson:
    * [QTBUG-33229] The Writer and the Parser now fully accept non-character
      unicode points.
+   * The Writer will no longer write inf, -inf and nan for infinites and NaN
+     values, which resulted in parsing back as strings. Instead, it will now
+     output null.
+   * The Writer now emits numeric values with full numeric precision. This

+     now works with a receiver object. The connection will be removed when
+     the either the sender or receiver objects are destroyed.
+
+ - QPluginLoader:
+   * QPluginLoader will no longer load the plugins on Mac OS X and iOS
+     systems when scanning for valid plugins.
+   * Added QPluginLoader::staticPlugins(), which returns the list of
+     built-in plugins (linked to the executable and any loaded libraries).
+
+ - QProcess:
+   * [QTBUG-32958] Fixed a bug that would cause QProcess to crash if
+     waitForStarted() were called after an unsuccessful start()
+   * Added QProcess::nullDevice(), which returns the platform's "blackhole"
+     device (/dev/null on Unix, NUL on Windows). This can be used with
+     QProcess::setStandardOutputFile.
+   * Added enum values QProcess::ForwardedOutputChannel and
+     QProcess::ForwardedErrorChannel, which allow for more fine-grained
+     control over which channel is forwarded and which one is captured.
+   * Added QProcess::ForwardedInputChannel, which allows for stdin to be
+     forwarded to this process's input.
+   * [QTBUG-32979] On Unix, QProcess now correctly forwards the siginfo_t
+     and context parameters of the signal handler to the previous handler.
+
+ - QScopedPointer:
+   * Added QScopedPointerDeleteLater, a new class that can be used as the
+     second template to QScopedPointer and will call deleteLater() on the
+     pointer when it goes out of scope.
+
+ - QSocketNotifier:
+   * Fixed a bug that caused socket notifiers not to be re-enabled after

  - Status bar visibility is now controlled by Qt, so the window state will
    override settings in the AndroidManifest.xml. The default is still to
    show the status bar (QWindow::showMaximized()). Use
    QWindow::showFullScreen() to hide it.
+ - Implemented support for accessibility on Android.

+Qt for OS X
+-----------
+
+ - Qt for OS X is now identified by the macro Q_OS_OSX. This complements the
+   existing Q_OS_DARWIN macro (which identifies the open source kernel and
+   could identify non-Apple products) and Q_OS_MAC, which is defined for
+   both OS X and iOS. The old macro Q_OS_MACX is now deprecated.
+ - Qt no longer complains about new versions of OS X that haven't been
+   released yet. This will allow Qt 5.2 and future versions to build on
+   future versions yet to be released. Note that those versions are not
+   supported until official announcement by the Qt Project.
+ - Added a number of functions to QtCore to convert to and from
+   CFString/NSString and QString, CFURL/NSURL and QUrl.
