+* Important Behavior Changes *
+****************************************************************************
+
+ - SIMD support in CPUs:
+ * [QTBUG-30440] Qt no longer checks for support for the Neon FPU on
+ ARM platforms at runtime. Code optimized for Neon must be enabled
+ unconditionally at compile time by ensuring the compiler supports
+ Neon. You may need to edit your mkspec for that.
+
+ * Qt now automatically generates code for processors supporting SSE2
+ on i386 platforms. To disable this, pass the -no-sse2 option during
+ Qt configuration. Since this feature has been present on CPUs for
+ 10 years and since Qt no longer checks for runtime support for
+ SSE2, we strongly encourage users to leave the default setting on
+ for best performance.
+ - For Linux distributions that must retain support for CPUs without
+ SSE2, we recommend doing two builds of Qt and installing the
+ SSE2-enabled libraries in the LIBDIR/sse2 directory (specially
+ QtGui, QtQml and QtQuick libraries). Tools, plugins, and examples
+ are not affected.
+ - See discussion on the Qt development mailing list:
+ http://lists.qt-project.org/pipermail/development/2013-November/014085.html
+
+ - SSL and security:
+ * The default set of ciphers used by QSslSocket has been changed to
+ exclude ciphers that are using key lengths smaller than 128
+ bits. These ciphers are still available and can be enabled by
+ applications if required.
+ * [QTBUG-20666] Support for DH and ECDH key exchange cipher suites
+ when acting as an SSL server has been made possible. This change
+ means the you can now implement servers that offer forward-secrecy
+ using Qt.
+ * Running Qt applications that are setuid is no longer allowed by
+ default. If you really need to do this then you can call
+ QCoreApplication::setSetuidAllowed(true) before creating the
+ QCoreApplication instance.
+
+ - UTF-8 decoding:
+ * The QString and QTextCodec UTF-8 decoder changed behavior slightly:
+ when it encounters invalid sequences, it will insert one
+ replacement character per byte that is invalid, instead of one
+ replacement character for the whole invalid length.

+
+****************************************************************************
+* Library *
+****************************************************************************
QtCore
------
- Added QSignalBlocker, a RAII-style wrapper around
QObject::blockSignals().
+ - QLibraryInfo provides information on how Qt was built.
+ - Added class QMarginsF to support handling margins with floating-point
+ values.
+
+ - Atomic support:

+ bit-manipulation operations are also provided, both in operator and in
+ fetchAndXxxYyyyyy modes.
+
+ - Event loop:
+ * [QTBUG-36611] QCoreApplication::hasPendingEvents and
+ QAbstractEventDispatcher::hasPendingEvents are now deprecated. Please
+ refer to the documentation for more information.

+ style.
+ * All qCDebug categories are enabled by default, except for Qt's own
+ categories.
+ * The logging framework can now be configured with an .ini file.
+ * Q_LOGGING_CATEGORY and Q_DECLARE_LOGGING_CATEGORY now return a const
+ object.
+
+ - QByteArray:

+
+ - QChar:
+ * Added JoiningType enum and joiningType() method that deprecates the
+ old QChar::Joining enum and joining() method.
+
+ - QFileSelector:
+ * [QTBUG-35073] The identifier for OS X has been changed back to
+ 'osx' from 'mac', and 'mac' and 'darwin' have now been added as
+ selectors for Darwin OS (which is the base of both OS X and iOS).
+
+ - QHash/QSet:
+ * Added qHash overloads for float, double and long double.
+
+ - QJsonArray:
+ * Added convenience methods to QJsonArray for appending QJsonValues
+
+ - QJsonValue:
+ * Added constructor to QJsonValue for const char *
+ * QJsonValue::fromVariant() will now convert single-precision Floats
+ into Doubles instead of Strings
+
+ - QMargins:
+ * Added missing addition and subtraction operators.
+
+ - QProcess:
+ * [QTBUG-26136] Added processId() to QProcess. This function will,
+ unlike pid(), return the actual process identifier on both Windows
+ and Unix.
+
+ - QRect:
+ * Added QMargins subtraction operator.
+
+ - QSettings:
+ * [QTBUG-9824][QTBUG-21062][QTBUG-22745] QSettings now returns the
+ correct value for isWritable() when using SystemScope settings.
+
+ - QSortFilterProxyModel:
+ * [QTBUG-30662] Fixed sorting when a previously empty proxy model
+ becomes populated because of a change in the filter.
+
+ - QStandardPaths:
+ * [QTBUG-34631] Added QStandardPaths implementation for Android.
+
+ - QString:
+ * Added QLatin1String overload of contains()
+ * QString::toUcs4 now does not return invalid UCS-4 code units belonging
+ to the surrogate range (U+D800 to U+DFFF) when the QString contains
+ malformed UTF-16 data. Instead, U+FFFD is returned in place of the
+ malformed subsequence.
+
+ - QTextCodec:
+ * Encoding a QString in UTF-32 will now replace malformed UTF-16
+ subsequences in the string with the Unicode replacement character
+ (U+FFFD).
+
+ - QVarLengthArray:
+ * Added the indexOf, lastIndexOf and contains functions to
+ QVarLengthArray. These functions make the class more similar to
+ QVector.
+
+ - Windows:
+ * [QTBUG-35194] Now QStandardPaths::DownloadLocation returns the proper
+ path for Windows Vista and up
+
+QtDBus
+------
+

+ introspection data
+
+ - QDBusServer:
+ * Added method to QDBusServer to allow anonymous client connections,
+ even if the connecting client is not authenticated as a user.

- Added setSwapInterval() to QSurfaceFormat. Platforms that support
setting the swap interval are now defaulting to the value of 1,
meaning vsync is enabled.
+ - [QTBUG-35220] Reading bmp images with alpha channel is now supported
+ - [QTBUG-36394] The main Embedded Linux platform plugins (eglfs, linuxfb,
+ kms) are changed to behave identically with regards to terminal keyboard

+ - Accessibility on Linux now reports the active state correctly.
+ - [QTBUG-36483] Qt builds on Windows can now be configured for dynamic
+ loading of the OpenGL implementation. This can be requested by passing
+ -opengl dynamic to configure. In this mode no modules will link to
+ opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will
+ dynamically choose between desktop and Angle during the first GL/EGL/WGL
+ call. This allows deploying applications with a single set of Qt
+ libraries with the ability of transparently falling back to Angle in
+ case the opengl32.dll is not suitable, due to missing graphics drivers
+ for example.
+ - Added class QPageLayout to support handling page layouts including the
+ page size, orientation and margins.

+
+ - QOpenGLFramebufferObject:
+ * [QTBUG-35881] Added takeTexture() for retrieving and detaching the
+ texture from the framebuffer object.
+
+ - QPageSize:
+ * Added new QPageSize class to implement Adobe Postscript PPD standard
+ page sizes. This class supports the standard page sizes, names and
+ keys from the PPD standard, and provides convenient size and rect
+ conversion methods.
+
+ - QPagedPaintDevice:
+ * [QTBUG-27685][QTBUG-25744] Paged paint devices such as QPrinter and
+ QPdfWriter now support all Postscript standard page sizes.

+ necessary plugins so that static applications can print.
+ - CUPS 1.4 is now required for print support on Linux and other *nix
+ platforms.
+
+ - QPrintPreviewDialog:
+ * [QTBUG-36561] Fixed initialization of QPrintPreviewDialog's image
+ resources for static builds.
+
+ - QPrinter:
+ * QPrinter can now use QPageSize and QPageLayout in the public api to
+ control the page layout for a print job.
+
+ - QPrinterInfo:
+ * [QTBUG-35248] Added new public api for isRemote(), state(),
+ defaultPageSize(), supportedPageSizes(), supportsCustomPageSizes(),
+ minimumPhysicalPageSize(), maximumPhysicalPageSize(),
+ supportedResolutions(), availablePrinterNames(), and
+ defaultPrinterName(). The use of availablePrinters() is discouraged
+ due to performance concerns.

+ new tag of the form
+ <duration msecs="123"/> is added to each test function and the test as a
+ whole.
+ - Added a CSV logging mode that is suitable for importing benchmark
+ results into spreadsheets. This can be enabled by the -csv option on the
+ command-line. The CSV logging mode will not print test failures, debug
+ messages, warnings, etc.
+ - QtTest now prints an escaped version of QStrings that failed to compare
+ with QCOMPARE. That is, instead of converting non-printable characters
+ to question marks, QtTest will print the Unicode representation of the
+ character in question.

+
+Linux
+-----
+
+ - Systems with systemd may now pass -journald to configure to send

+ set to a non-empty value.
+
+OS X
+----
+
+ - [QTBUG-18980][QTBUG-38246] Use CoreText text shaping engine for
+ support of complex scripts. If required, the shaping engine used in
+ previous versions can be preferred by configuring Qt with
+ -no-harfbuzz. Alternatively, the QT_HARFBUZZ environment variable
+ could be set to "old".
+
+Windows
+-------
+
+ - Introduced experimental direct2d platform plugin for Windows. This
+ plugin shares most code with the current windows plugin, but
+ substitutes a direct2d-based paint engine for window backing stores
+ and pixmaps.
+
+ - QtWidgets / QFileDialog:
+ * Handled the case of having trailing spaces in a filename correctly so
+ if the filename ends up being empty that the parent path is used
+ instead.
+
+ - Windows Embedded:
+ * Fixed building issue when configuring Qt with -qtlibinfix
+
