| * 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). |
| - Fixed a crash when closing multiple popups at once. |
