+
+    Add default return values to switch statements
+    
+    We are using g_assert_not_reached() without doing anything, assuming it
+    aborts the program. In release builds however, it is ignored.

+- Update to version 3.92.1:
+  + Drop autotools support. Meson 0.42.1 is now required
+  + Implement most of CSS3 font-variant
+  + Add an Emoji chooser to GtkEntry
+  + Add new input hints for Emoji input
+  + Remaining widgets have been ported to GtkSnapshot
+  + GtkLabel and GtkEntry have been ported to use GSK
+  + Add a way for GtkOverlay to blur behind children. This is has a
+    demo in gtk4-demo
+  + Add support for native file choosers on older OS X versions
+  + Add support for libcloudproviders in GtkPlacesSidebar
+  + Non-windowed widgets are now allowed to have a size of 0x0
+  + Allow tiled windows to be resized. Under wayland, this uses
+    version 2 of the gtk-shell protocol. Under X, it uses the
+    _GTK_EDGE_CONSTRAINTS property
+  + Input handling changes
+    - GdkEvent has new accessors for fields
+    - Traditional event signals (eg ::key-press-event) are now emitted from
+      an event controller
+    - Most widgets inside gtk have stopped using traditional event signals
+    - GDK_SEAT_CAPABILITY_ALL_POINTING now includes touch events
+  + Scrollbars allow middle-click to jump to a position again

+  + Updated translations.
+- Add meson BuildRequires and replace configure/make/make_install
+  calls with meson/meson_build and meson_install: follow upstreams
+  port to meson as build system.
+- Add gcc-c++ BuildRequires: small parts of GTK+ now are written in
+  C++.
+- Add gtk-doc BuildRequires: in order to build man-pages,
+  documentation needs to be enabled, which in turn requires
+  gtk-doc. In the past, we provided upstream shipped documentation.
+- Add gtk4-return-nonvoid.patch: Fix 'reaches end of non-void
+  function without return value', taken from git.
+- Add rpmlintrc: multiple GTK4 libraries are not goint to be
+  supported in parallel and the name will stabilize.
