+****************************************************************************
+*                               Qt 5.9.4 Changes                           *
+****************************************************************************
+
+QtCore
+------
+
+ - [QTBUG-64529] Fixed a compilation issue with qfloat16 if AVX2 support is
+   enabled in the compiler. Since all processors that support AVX2 also
+   support F16C, for GCC and Clang it is recommended to either add -mf16c
+   to your build or to use the corresponding -march= switch.
+
+ - QCoreApplication:
+   * [QTBUG-58919] Fixed a crash if QCoreApplication is recreated on Windows
+     and the passed argv parameter is different.
+
+ - QFileInfo:
+   * [QTBUG-30148] Fixed isWritable() on Windows to return whether the given
+     file is writable only under current privilege levels. Previously, the
+     result would take into account privilege elevation.
+
+ - QObject:
+   * Fixed a crash that could happen if the context QObject pointer passed to
+     new-style connect() was null.
+
+ - QStandardPaths:
+   * On Windows, it is now possible to resolve configuration paths even
+     without QCoreApplication created.
+
+ - QString:
+   * QString::unicode(), constData() and `data() const` do not return a
+     NUL-terminated string. This was true before, but the documentation
+     claimed the opposite.
+
+ - QVector:
+   * Fixed a problem when calling removeAll() on an element from the
+     container, if the container had more than one copy of the that element.
+
+ - QXmlStreamWriter:
+   * [QTBUG-63538] Empty namespace URIs are now possible.
+
+ - State Machine:
+   * [QTBUG-61463] Fixed a failed assertion that could happen when emitting a
+     signal from another thread.
+
+QtNetwork
+---------
+
+ - QUdpSocket:
+   * [QTBUG-64718] Fixed a regression from Qt 5.9.3 caused by an apparent
+     Win32 API quirk we triggered when using readDatagram(), resulting in
+     an invalid QHostAddress sender address. receiveDatagram() was not
+     affected.
+
+QtPrintSupport
+--------------
+
+ - QPrintDialog:
+   * [QTBUG-63933] Properly pre-select explicitly requested printer on
+     Unix.
+
+QtWidgets
+---------
+
+ - QFileSystemModel:
+   * [QTBUG-46684] It is now possible to enable per-file watching by
+     setting the environment variable QT_FILESYSTEMMODEL_WATCH_FILES,
+     allowing to track for example changes in file size.
+   * [QTBUG-64098] Fixed column alignment issues.
+   * [QTBUG-62841] Fixed assert when monitoring directories.
+
+- QPixmapCache:
+   * [QTBUG-65475] Changing application palette runtime will now affect
+     (and invalidate) cached widget pixmaps used by the current style.
+
+- QTreeView:
+   * [QTBUG-57538] Fixed issue with drag and drop sometimes being inaccurate.
+   * [QTBUG-63396] Fixed issue with child indicator not drawn correctly in RTL mode.
+   * [QTBUG-63869] Fixed key navigation issue when using hidden items.
+   * [QTBUG-8376]  Fixed row heights being wrong because of hidden columns.
+
+- QTableView:
+   * [QTBUG-60219] Fixed grid lines being drawn outside header.
+
+- QHeaderView:
+   * [QTBUG-53221] Fixed assert in QHeaderView because of layout changes.
+   * [QTBUG-65017] Fixed a font issue when using drag and drop.
+   * [QTBUG-56520] Fixed drawing issues in RTL mode.
+   * [QTBUG-41124] [QTBUG-54610] Fixed update issues.
+
+- QWidget:
+   * [QTBUG-61213] Fixed crash related to the usage of Qt::WA_WindowPropagation.
+
+- QPlainTextEdit:
+   * [QTBUG-62818] Fixed QPlainTextedit hanging because of scrollbar usage.
+
+- QMenu:
+   * [QTBUG-63576] Fixed HiDPI issue in QFusionStyle for QCheckBoxes in QMenus.
+   * [QTBUG-59794] Fixed HiDPI issue in QMenu when using several screens.
+
+- QMenuItem:
+   * [QTBUG-64055] Fixed drawing issue when setting a font style.
+
+- QAbstractButton:
+   * [QTBUG-53244] Fixed issue with released signal not being emmited when using
+     several mouse buttons at the same time.
+
+- QGraphicsEffect:
+   * [QTBUG-60231] Fixed crash when using child widgets with graphic effects.
+
+Third-Party Code
+----------------
+
+ - [QTBUG-65138] Fixed glitch in attribution documentation for Freetype
+   licenses / Qt Gui.
+
+Platform Specific Changes
+-------------------------
+
+ - eglfs:
+   * [QTBUG-65119] Fixed crash when using cursors and multiple GL contexts.
+
+ - iOS/tvOS:
+   * Qt will now take the safe area margins of the device into account when
+     computing layouts for QtWidgets.
+
+ - macOS:
+   * [QTBUG-57487][QTBUG-54160] If you have changed the button mapping of
+     your Wacom tablet in System Preferences, it will be respected by Qt
+     applications now. To revert to the old behavior, set the environment
+     variable QT_MAC_TABLET_IGNORE_BUTTON_MAPPING.
+
+ - macOS/iOS:
+   * [QTBUG-63476] Fixed an issue where text using one of the system theme
+     fonts would under certain circumstances display random glyphs.
+
+ - INTEGRITY:
+   * Added mkspec for INTEGRITY Qualcomm s820 MSM8996AU
+
+ - QNX:
+   * [QTBUG-64033] Fixed a build issue when using slog2 in QNX7.
+
+ - X11 / XCB:
+   * [QTBUG-62224] Minimal libXi version requirement has been updated from
+     1.7.4 to 1.7.5. This is because XIAllowTouchEvents is known to
+     deadlock with libXi 1.7.4 and earlier. When touch events are never
+     received, this is not an issue. Plain mouse / keyboard systems are not
+     affected.
+
+configure & build system
+------------------------
+
+ - [QTBUG-61431][QTBUG-62521] Fixed processing of *_LIBS_{DEBUG|RELEASE}=
+   configure command line arguments.
+ - [QTBUG-63452] Fixed bogus complaints about DUMMY platform when
+   re-configuring a build on a different day than initially configuring it.
+ - Fixed logic errors in the conditions of various Qt features.
+
+qmake
+-----
+
+ - [QTBUG-41246][QTBUG-50896][Xcode] It is now possible to enable generation
+   of dSYM debug symbols for release builds.
+ - [iOS] Fixed compilation of asset catalogs for a generic simulator.
