****************************************************************************
-* Library *
+* Deprecation Notice *
****************************************************************************
+ - The Q_COMPILER_xxx macros for C++14 compiler features introduced in Qt
+ 5.3 are deprecated and will not be updated for new compilers either.
+ User code should be changed to use the macros from Standing Document 6
+ instead:
+ http://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations.
+ This does not affect C++11 feature macros.
+
+****************************************************************************
+* Important Behavior Changes *
+****************************************************************************
+
+ - QExplicitelySharedDataPointer's copy constructor which performs a
+ static_cast from "X *" to "T *" (when constructing a
+ QExplicitlySharedDataPointer<T> from a QExplicitlySharedDataPointer<X>)
+ doesn't perform a static_cast from "X *" to "T *" any more. Instead, an
+ implicit cast is now performed. This change will break compilation of code
+ that relied on the downcast (i.e. cast towards a more derived type) of the
+ templated type when copy constructing a QExplicitelySharedDataPointer
+ object. Please refer to the class documentation for more information about
+ this issue and a workaround to keep old code compiling.
+ - QImageReader now automatically rotates JPEG images according to Exif
+ orientation
+ - [QTBUG-18980] HarfBuzz-NG is now the default shaper on all platforms.
+ This results in a better shaping results for various languages, better
+ performance, and lower memory consumption.
+ - [QTBUG-41858] Changed QStringRef::right() to be consistent with
+ QString::right(). The function now returns the N right-most characters,
+ like the documentation already claimed.
+ - The mutable Java-style iterators like QListMutableIterator and
+ QHashMutableIterator no longer set the parent container to unsharable
+ mode. If you create a copy of the container being iterated on after the
+ iterator, any changes done with the iterator might affect the copy too.
+
+ - Logging (including qDebug and qWarning):
+ * Support for the deprecated environment variables QT_NO_JOURNALD_LOG
+ and QT_ANDROID_PLAIN_LOG has been removed. Instead, set
+ QT_LOGGING_TO_CONSOLE to 1 to force logging to the console (stderr).
+ Set that variable to 0 to force logging to the system-specific event
+ log (if any).
+ * [QTCREATORBUG-12564] Log output will now go to the system log (if
+ support for it was compiled into Qt) if the application has no
+ controlling terminal or console window. Set QT_LOGGING_TO_CONSOLE to 1
+ to force logging to go to stderr.
+
+ - QSettings:
+ * [QTBUG-41812] QSettings::value() now returns an invalid QVariant when
+ passing an empty key. The code path ran into an assert, which was only
+ noticeable in debug builds.
+ * [QTBUG-21739] The locking mechanism inside QSettings has changed
+ and is no longer compatible with the one of previous versions of
+ Qt. There might be corruption if two applications running different
+ versions of Qt are writing to the same config file at the same
+ time. You must also now have write permissions in the directory
+ containing the settings file in order to write settings.
+

+* Library *
+****************************************************************************
+
+QtConcurrent
+------------
+
+ - [QTBUG-17220] run() now optionally takes as its first argument the
+ QThreadPool to run the task on.
+
QtCore
------
- Added QEnableSharedFromThis, a class that allows obtaining a
QSharedPointer for an object already managed by a shared pointer.
+ - Added qHashBits() to aid implementing qHash() overloads for custom
+ types.
+ - Added new QByteArrayList class.
+ - Added QStorageInfo class to retrive information about mounted volumes
+ and drives
+
+ - Logging:
+ * QT_MESSAGE_PATTERN can include a backtrace using %{backtrace}
+ * Added QtMsgType argument to QLoggingCategory constructor and
+ Q_LOGGING_CATEGORY macro that controls the default category
+ configuration.
+ * File, line, function information are not recorded anymore for logging
+ statements in release builds. Set QT_MESSAGELOGCONTEXT explicitly to
+ enable recording in all configurations.
+
+ - QAbstractProxyModel:
+ * [QTBUG-39549] QAbstractProxyModel now forwards the drop-related API.
+
+ - QByteArray:
+ * Added convenience methods to convert directly to and from std::string.
+ * Fixed a bug that would cause QByteArray to stop converting toUpper or
+ toLower at the first embedded null character.
+
+ - QCommandLineParser:
+ * Added addOptions() method.
+
+ - QElapsedTimer:
+ * Is no longer a POD; its default constructor now initializes the object to
+ an invalid QElapsedTimer
+
+ - QFlags:
+ * [QTBUG-39786] Added initializer_list constructor
+
+ - QFuture:
+ * [QTBUG-17220] Can now be used with any QThreadPool, not just
+ globalInstance().
+
+ - QPair:
+ * Can now be used in C++11 constexpr contexts.
+
+ - QSaveFile:
+ * Now follows symbolic links when writing to a link instead of
+ replacing the link with the contents.

+ * [QTBUG-38483] QStandardPaths now has new enumeration values
+ AppDataLocation, AppLocalDataLocation to be able to differentiate
+ between roaming and local paths on the Windows operating system.
+ DataLocation is deprecated in favor of AppDataLocation.
+
+ - QString:
+ * QString can now split a string to a list of QStringRef.
+ * Added the QStringRef::split() function
+
+ - QTextStream:
+ * QTextStream now uses group separators when writing floating-point
+ numbers when the locale is not the C locale. The old behavior can be
+ restored by setting QLocale::OmitGroupSeparator on the locale.
+
+ - QTimer:
+ * [QTBUG-26406] Implemented new style connect syntax, including
+ functors, in QTimer::singleShot
+
+ - QUrl:
+ * QUrl::fromLocalFile now returns an empty URL if the input string is
+ empty.
+
+ - QVariant:
+ * [QTBUG-40363] Fixed ordered comparison between QVariants that do not
+ match but produce identical toString output.

+
+ - QWeakPointer:
+ * Added lock() method for std::weak_ptr compatibility.

+ - Blocking calls that take a long time will now generate a warning. The
+ time taken may be tuned using the environment variables
+ Q_DBUS_BLOCKING_CALL_MAIN_THREAD_WARNING_MS and
+ Q_DBUS_BLOCKING_CALL_OTHER_THREAD_WARNING_MS. The value represents (in
+ milliseconds) how long before a blocking call is warned about. A value
+ below zero disables the warning, a value of zero will warn about all
+ blocking calls.
+
+QtGui
+-----
+
+ - Added QPixelFormat class.
+ - [QTBUG-38168] QtGui's OpenGL headers are now automatically including the
+ highest available header (gl31.h, gl3.h or gl2.h) in OpenGL ES builds.
+ - [QTBUG-36483] Dynamic OpenGL implementation loading is now supported on
+ Windows. This requires Qt to be configured with -opengl dynamic.
+ - [QTBUG-39583] Keymaps are now changeable at runtime when using eglfs.
+ - [QTBUG-40841] environment variable QT_DBL_CLICK_DIST customizes the
+ amount of movement allowed when detecting a double click.
+
+ - Clipboard:
+ * [QTBUG-41852] Fixed a memory leak in setMimeData() when the platform
+ plugin did not support the requested mode.
+

+ * [QTBUG-25998] Added support for 10-bit per color channel image
+ formats.
+
+ - QOpenGLBuffer:
+ * [QTBUG-38168] Added QOpenGLBuffer::mapBufferRange().
+
+ - QOpenGLFramebufferObject:
+ * Introduced an argument to QOpenGLFramebufferObject::toImage() to save
+ mirroring the result.
+ * Added support 10-bit per color channels formats as the internal
+ framebuffer format, making it possible to render in that precision.
+
+ - QOpenGLTextureCache:
+ * Added support for uploading common QImage formats directly to OpenGL,
+ if supported by the OpenGL implementation.
+
+ - QPicture:
+ * [QTBUG-20578] QPicture now serializes its data properly by also
+ accounting for QDataStream versions greater than Qt 4.5.
+
+ - Tablet support:
+ * [QTBUG-39458] Added buttons to QTabletEvent

+
+ - QSslSocket:
+ * [QTBUG-28471] Added support for finding the version of SSL/TLS in
+ use by a connection.
+ * Added accessors for the version of OpenSSL used at build-time. This
+ will help when debugging problems caused by a mismatch with the
+ run-time version.
+ * [QTBUG-1565] Support for loading PKCS#12 bundles was added. These are
+ often used to conveniently transport keys and certificates,
+ particularly when making use of client certificates.
+
