+Qt 5.13 introduces many new features and improvements as well as bugfixes
+over the 5.12.x series. For more details, refer to the online documentation
+included in this distribution. The documentation is also available online:
+The Qt version 5.13 series is binary compatible with the 5.12.x series.
+Applications compiled for 5.12 will continue to run with 5.13.
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker:
+Each of these identifiers can be entered in the bug tracker to obtain more
+information about a particular change.
+* General *
+ - libwayland 1.8.0 is now required.
+ - Code generated by qtwaylandscanner now includes wayland-client-core.h
+ and wayland-server-core.h instead of wayland-client.h and
+ wayland-server.h. This might break source compatibility for code using
+ custom wayland extensions.
+* Compositor *
+ - [QTBUG-70662] Added QWaylandQuickItem::mapFromSurface which converts
+ points in Wayland surface coordinates to points in QQuickItem
+ coordinates.
+ - Fixed a bug where xdg-shell popups were misplaced when devicePixelRatio
+ was not 1.
+ - QWaylandSurface::destinationSize has been added which returns the size
+ of the surface that will be displayed on the screen in surface
+ coordinates.
+ - Fixed a bug where QWaylandSurface::inputRegionContains would return true
+ for some points outside surfaces with buffer scale > 1.
+ - Fixed a bug which caused ShellSurfaceItems for surfaces with buffer
+ scale > 1 to move too much when resizing interactively.
+ - QWaylandSurface::size has been deprecated. Use bufferSize or
+ destinationSize instead.
+ - Added support for linux-dmabuf-unstable-v1.
+ - Added support for the viewporter Wayland extension.
+ - Added a missing change signal for WaylandQuickItem.compositor.
+ - Added deprecated support for the deprecated the wl_scaler extension.
+ - Fixed a bug where virtual keyboard did not send Enter event to clients.
+* QPA plugin *
+ - The environment variables, QT_WAYLAND_CLIENT_BUFFER_INTEGRATION and
+ QT_WAYLAND_SERVER_BUFFER_INTEGRATION, now takes precedence over what is
+ communicated through the qt_hardware_integration wayland interface.
+ - The private window decoration API method,
+ QWaylandAbstractDecoration::startResize, now takes Qt::Edges argument
+ instead of a wl_shell_surface_resize enum. This will break window
+ decoration plugins written for older versions of Qt Wayland.
+ - Shell integrations are now features that can be enabled or disabled at
+ build time.
+ - Clients now follow the keyboard key repeat delay and interval configured
+ by the compositor.
+ - Added support for fullscreen-shell unstable v1.
+ - A window menu is now shown when the window decorations are right-clicked
+ (if supported by the compositor).
+ - Minimum and maximum window size is now supported with the xdg-shell and
+ xdg-shell-v6 shell integrations.
+ - xdg-shell (stable and v6) window geometry is now sent every time the
+ window is resized.
+ - Fixed a bug where window decorations were to small for for the content
+ when QT_SCALE_FACTOR was set.
+ - [QTBUG-54786] Fixed a bug where pasting from the clipboard would prefer
+ ASCII over UTF-8, causing loss of special characters.
+ - [QTBUG-68571] Fixed a bug where the DPI of bitmap cursors were not sent
+ to the compositor, leading to the compositor incorrectly scaling the
+ cursor up or down.
+ - [QTBUG-68571] Fixed a bug where bitmap cursor hotspots were off when the
+ screen scale factor was different from the bitmap cursor device pixel
+ ratio.
+ - Fixed a leak of wl_data_offers.
+ - Cursors on high DPI screens are now scaled up if the cursor theme does
+ not have an appropriate high resolution version.
+ - Fixed a bug where QGuiApplication::screens() and primaryScreen() would
+ return initial screens in the reverse order they were added by the
+ compositor. QGuiApplication::primaryScreen() will now return the first
+ output added by the compositor.
+ - Fixed a bug where windows with an OpenGL Core context and window
+ decorations didn't work.
+ - Fixed a build issue where the platform plugin would not be built if the
+ compositor wasn't build.
+ - The non-blocking version of eglSwapBuffers is now used, if supported.
+ This fixed a bug where minimized windows would block the event loop.
+ - Windows that don't get frame callbacks from the compositor within 100 ms
+ are now set as not exposed. This should stop most clients from rendering
+ unnecessary frames to minimized or hidden windows.
+ - Improved startup time by moving key Compose table parsing from startup
+ to the first use (a key was pressed).
+ - Selecting a module via QT_IM_MODULE now works as documented.
+ - Fixed a bug where Ctrl + <some letter> did not work with non-latin
+ keyboard layouts. Other shortcut sequences with non-latin keys not
+ working also have been fixed now.
+ - Fixed a bug where shortcuts with modifiers that change resulting key
+ would not work as expected.
+ - Added support for xdg-output-unstable-v1 version 2. This means
+ QScreen::name(), will now typically return "VGA-1", "WL-1", "DP-2",
+ "HDMI-A-1" and similar instead of "Screen25", "Screen26", "Screen27"
+ etc. (on supported compositors).
