+Qt 5.12.4 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 5.12.0 through 5.12.3.
+
+For more details, refer to the online documentation included in this
+distribution. The documentation is also available online:
+
+https://doc.qt.io/qt-5/index.html
+
+The Qt version 5.12 series is binary compatible with the 5.11.x series.
+Applications compiled for 5.11 will continue to run with 5.12.
+
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker:
+
+https://bugreports.qt.io/
+
+Each of these identifiers can be entered in the bug tracker to obtain more
+information about a particular change.

+
+ - 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.
+ - Fixed a crash on xdg-shell v5 when creating a popup without a valid
+   parent.
+ - Fixed a protocol error when an application tried to render to a window
+   before a shell or sub-surface was created.
+ - Fixed a crash when closing multiple popups at once.

+      Backward incompatible changes are done by bumping the version number in
+      the protocol and interface names and resetting the interface version.
+      Once the protocol is to be declared stable, the 'z' prefix and the

+ * \qmltype XdgOutputManagerV1
+ * \inqmlmodule QtWayland.Compositor
+ * \since 5.14
+ * \brief Provides an extension for describing outputs in a desktop oriented fashion
+ *
+ * The XdgOutputManagerV1 extension provides a way for a compositor to describe outputs in a way
+ * that is more in line with the concept of an output on desktop oriented systems.
+ *
+ * Some information may not make sense in other applications such as IVI systems.
+ *
+ * Typically the global compositor space on a desktop system is made of a
+ * contiguous or overlapping set of rectangular regions.
+ *
+ * XdgOutputManagerV1 corresponds to the Wayland interface, \c zxdg_output_manager_v1.
+ *
+ * To provide the functionality of the extension in a compositor, create an instance of the
+ * XdgOutputManagerV1 component and add it to the list of extensions supported by the compositor,
+ * and associated each XdgOutputV1 with its WaylandOutput:
+ *
+ * \qml \QtMinorVersion
+ * import QtWayland.Compositor 1.\1
+ *
+ * WaylandCompositor {
+ *     XdgOutputManagerV1 {
+ *         WaylandOutput {
+ *             id: output1
+ *
+ *             position: Qt.point(0, 0)
+ *             window: Window {}
+ *
+ *             XdgOutputV1 {
+ *                 name: "WL-1"
+ *                 logicalPosition: output1.position
+ *                 logicalSize: Qt.size(output1.geometry.width / output1.scaleFactor,
+ *                                      output1.geometry.height / output1.scaleFactor)
+ *             }
+ *         }
+ *
+ *         WaylandOutput {
+ *             id: output2
+ *
+ *             position: Qt.point(800, 0)
+ *             window: Window {}
+ *
+ *             XdgOutputV1 {
+ *                 name: "WL-2"
+ *                 logicalPosition: output2.position
+ *                 logicalSize: Qt.size(output2.geometry.width / output2.scaleFactor,
+ *                                      output2.geometry.height / output2.scaleFactor)
