 - [QTBUG-68619] In Qt 5.11.0, support for selecting a platform plugin
   based on the XDG_SESSION_TYPE environment variable was added. On
   gnome-shell, however, bugs—in both Qt and gnome-shell—made many
   widget applications almost unusable. So until those bugs are fixed
   XDG_SESSION_TYPE=wayland is now ignored on gnome-shell.

QtCore
------

 - Item Models:
   * [QTBUG-18001] Fixed a bug that made selecting or deselecting a column if
     some flags are applied to certain items.
   * [QTBUG-44962][QTBUG-67948][QTBUG-68427] Fixed issues with the replacing
     of the source model in QSortFilterProxyModel that could lead to empty
     views or failed assertions.

 - QJsonDocument
   * [QTBUG-61969] Fixed a number of bugs in the parsing of binary data
     (QJson::fromRawData) that could lead to crashes or out-of-bounds access.

 - QLocale:
   * On Unix, when using LANGUAGE would lose information about script or
     country, without changing language, use the locale implied by LC_ALL,
     LC_MESSAGES or LANG.

 - QPointF/QRectF:
   * [QTBUG-60359][QTBUG-62161] Fixed an issue that led to inconsistent
     comparison results for the different edges of a rectangle.

 - QProcess:
   * [QTBUG-68472] On Unix, the QProcess SIGCHLD handler now restores errno
     on exit.
   * [QTBUG-67744] QProcess now properly reports an error state if it failed
     to create the communication pipes.

 - QSharedPointer:
   * [QTBUG-68300] Fixed a problem that made create() on a type with const
     qualification fail to compile.

QtNetwork
---------

 - QNetworkCookieJar:
   * [QTBUG-52040] Cookies will no longer be rejected when the domain
     matches a TLD. However (to avoid problems with TLDs), such cookies are
     only accepted, or sent, when the host name matches exactly.

QtWidgets
---------

 - [QTBUG-48325] Sending a key press event with sendEvent() now sends a
   ShortCutOverride event first to the widget to trigger any shortcuts set
   first.
 - [QTBUG-67533] QOpenGLWidget/QQuickWidget is now respecting AlwaysStackOnTop.
 - [QTBUG-60404] Fixed crash in QMacPanGestureRecognizer.
 - [QTBUG-67836] Fixed input method commits that end with newline.
 - [QTBUG-33855] Fixed issue with fonts in QHeaderViews
 - [QTBUG-56457] Fixed margin issue related to sections in QHeaderView.

Android
-------

 - [QTBUG-68344] QTemporaryFile does not try to use O_TMPFILE any more,
   to work around outdated sandbox restrictions of linkat(). This also fixes
   use of QSettings and QFile::copy().

Linux
-----

 - [QTBUG-68586] Fixed a bug that caused QFileSystemWatcher to print a warning
   if the file being watched did not exist. The class is documented to return
   the list of files that it could not watch.

macOS
-----

 - [QTBUG-60676] Fixed a bug in using QFileSystemWatcher to watch different
   file paths that shared a common prefix.

Windows
-------

 - [QTBUG-68514] Reverted a change that caused static binaries compiled
   with Visual Studio 2015 to crash on start-up. Note that this does not
   apply to Visual Studio 2017 static binaries, even though the crash stack
   traces are very similar: with 2017, the problem is compiler regression
   and requires updating to version 15.8 for the fix.

------------------------

 - [QTBUG-68478] Fixed parallel build of examples in some modules.

qmake
-----

 - [QTBUG-37417][CMake] Fixed missing include paths in private modules.
 - [QTBUG-47325] Fixed crash when $QMAKEFEATURES contains empty paths
   (e.g., due to a trailing colon).
 - [QTBUG-52474][Xcode] Fixed sources being excluded from Time Machine
   backups.
 - [QTBUG-66462][Darwin] Fixed overriding QMAKE_TARGET_BUNDLE_PREFIX in
   project files.
 - [QTBUG-68705][Xcode] Fixed build directory location of app bundles.
 - [Xcode] Fixed compatibility with Xcode 10 by opting out from the new
   build system.
 - [Darwin] Fixed .prl file lookup for suffixed frameworks.
 - Fixed look-up of relative files from extra compilers' .depend_command
   in shadow builds.
