 ****************************************************************************
+*                   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.

+   interest in updating support: INTEGRITY, VxWorks, Solaris on UltraSPARC
+   (with the Sun Studio compiler suite), AIX on POWER processors (with IBM
+   Visual Age compiler suite).

+****************************************************************************
 
 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:
+   * Added more operations to the atomic classes, including operator T(),
+     operator=(T), operator++, operator--. For the QAtomicInteger,
+     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.
+
+ - Logging:
+   * It is now possible for the qCDebug macros to be used in a printf
+     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:
+   * Added NSData/CDataRef converters for 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.
 
 QtGui

  - 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
+   input: it is turned off by default on all of these platforms. If this
+   feature is not desired, it can be disabled by setting the environment
+   variable QT_QPA_ENABLE_TERMINAL_KEYBOARD.
+ - [QTBUG-36374] Mouse hotplugging is now fully supported in eglfs when

+ - [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.
+ - [QTBUG-28813][QTBUG-29930][QTBUG-35836] Fixed regression in
+   arabic text rendering.
+ - [QTBUG-37332] GLES3 and desktop OpenGL are now fully supported with
+   EGL
+ - [QTBUG-36993] Native (that is, not distance field based) text
+   rendering is now functional on OpenGL 3.2+ core profiles too.
+
+ - Accessibility:
+   * [QTBUG-37204] Implemented text attributes to enable VoiceOver to read
+     QTextEdit and QPlainTextEdit.
+   * Assistive apps such as VoiceOver can now set the focus on widgets
+     and controls.
+
+ - QColor:
+   * Exported highly optimized methods for premultiply and unpremultiply of
+     QRgb values.
+
+ - QFont:
+   * Added qHash overload for this class.

+     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.
+
+ - QPdfWriter:
+   * The QPdfWriter now supports setting the PDF orientation, layout and
+     resolution by using QPageSize and QPageLayout.
+
+ - QTextLayout:
+   * [QTBUG-18060] Fixed visual cursor movement in bidirectional text.
+
+ - QWindow:
+   * QWindow::icon() now defaults to the application icon, which can be set
+     with QGuiApplication::setWindowIcon().
+
+QtNetwork
+---------
+
+ - [QTBUG-18714] Added support for the SPDY protocol (version 3.0).
+
+ - QNetworkReply:
+   * [QTBUG-30880] Added more (specific) HTTP status codes to NetworkError
+     enum.
+
+ - QSslConfiguration:
+   * [QTBUG-33208] Added support for the Next Protocol Negotiation (NPN)
+     TLS extension.
+
+QtPrintSupport
+--------------
+
+ - [QTBUG-29663] Made the Qt buildsystem automatically include the
+   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.
 
 QtSql

+
+ - QSqlError
+   * Now handles alphanumeric error codes. Used by QPSQL.  Old numeric
+     code is deprecated.
+
+QtTest
+------
+
+ - Added test duration to xml output. When running tests with xml output a
+   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.

+     Qt 5.0-5.2 is no longer sent.
+   * [QTBUG-33716] QWidgets embedded in QGraphicsProxyWidget are no longer
+     sent close events when the app is closed on OS X.
+   * [QTBUG-36178] Fixed an issue where stay-on-top widgets would cover
+     their own children on OS X.
+
+ - QWizard:
+   * [QTBUG-7484] Added NoCancelButtonOnLastPage option.
+   * [QTBUG-36192] Fixed frame when using Vista style/MSVC2012.
+
+ - Text support:
+   * [QTBUG-36444] Fixed off-by-one in the height of text background.
+
+ - Windows:
+   * [QTBUG-21371][QTBUG-4397] QWidget::restoreGeometry() now restores
+     maximized/full screen widgets to the correct screen.

+
+Android
+-------
+
+ - [QTBUG-34781] Fixed regression in "make install" on library projects on
+   Android so they can be used inside subdirs projects again.
+ - [QTBUG-36074] Fixed crash on populating large combo boxes or menus.
+ - [QTBUG-36528] Fixed QDir::entryList() for assets scheme to no longer
+   skip the first file in the directory.
+ - [QTBUG-30652] It is now possible to define a splash screen which will be
+   visible until the first window is created.
+ - [QTBUG-33704] Sped up first time directory listing in assets by using
+   pregenerated entry list.
+ - [QTBUG-37738] Fixed font merging problem which caused e.g. missing
+   glyphs for Arabic numerals.
+ - [QTBUG-36025] Fixed a memory leak in the clipboard
+
+ - Fonts:
+   * [QTBUG-36789] Fixed support for Arabic text.
+
+Linux
+-----
+
+ - Systems with systemd may now pass -journald to configure to send
+   logging output to journald. Logging will still be sent to stderr for
+   interactive applications (run from a tty) or with QT_NO_JOURNALD_LOG
+   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
+
+X11 / XCB
+---------
+
+ - Qt now supports XInput2 smooth scrolling events
