+Overview of Changes in GTK+ 3.93.0
+==================================
+
+Major changes:
+
+* GdkScreen has been removed. All screen-related APIs have equivalents
+  in GdkDisplay. This affects APIs in both GDK and GTK, for example,
+  the GtkWidget::screen-changed signal has been replaced by a new
+  ::display-changed signal. As part of this change, there is no longer
+  a GdkWindow representing the root window. The X11 backend has APIs
+  to get X screens and root windows.
+
+* GdkVisual has been removed.
+
+* GdkDeviceManager has been replaced by GdkSeat. 
+
+* Clipboard handling has been moved from GTK to GDK, and has been
+  modernized to provide an extensible, asynchronous, stream-based API.
+  This affects APIs in both GDK and GTK. GdkSelection has been replaced
+  by GdkContentFormats, GdkContentProvider, GdkContentSerializer and
+  GdkContentDeserializer. Selection-related events and APIs have
+  been removed.
+  This conversion is complete for copy-paste, the drag-and-drop APIs
+  are still in flux.
+
+* The GdkCursor API has been modernized. We no longer have the
+  GdkCursorType enumeration. Instead, can be created from names
+  or from GdkTextures. In GTK, we now have gtk_widget_set_cursor().
+
+* Settings and window-state changes have been converted from events
+  to signals on GdkDisplay and GdkWindow, respectively.
+
+* GdkEvent has been converted to an opaque GObject.
+
+* The GL renderer in GSK has been substantially completed, and is now
+  on par with the Vulkan renderer.
+
+* The use of GdkPixbuf in APIs has been reduced, and the GskTexture
+  object has been moved to GDK as GdkTexture, to take its place. This
+  change affects both GDK and GTK, for example the GtkAboutDialog::logo
+  property now accepts a GdkTexture. As part of these changes,
+  support for GdkPixbufAnimation has been dropped.
+
+* The handling of icon sizes has been changed. The GtkIconSize
+  enumeration allows selection normal or large icons now, and the
+  actual icon size is determined by the theme, using the -gtk-icon-size
+  CSS property. Among other things, this allows animating icon size changes.
+
+Smaller changes:
+
+* Build system:
+ - Meson can now be used to build GTK+ on Windows
+ - We install print backends again
+ - libepoxy 1.4 is required
+ - libcloudproviders 0.2.5 is required
+
+* GDK:
+ - gdk_keymap_get_for_display has been renamed to gdk_display_get_keymap
+ - We are no longer reading the GDK_DPI_SCALE environment variable
+ - The GdkX11Display::xevent signal has been added (to eventually replace event filters)
+ - gdk_pango_context_get_for_screen and gdk_pango_context_get have been dropped
+ - Default-display wrappers like gdk_set_double_click_time, gdk_beep, gdk_flush or
+   gdk_notify_startup_complete have been dropped
+ - gdk_display_set_program_class has been moved to the X11 backend
+ - The gdk_error_trap_push/pop APIs have been dropped, the X11 backend still has them
+
+* Wayland:
+ - The Wayland backend now implements the KDE server-side decoration protocol
+
+* Broadway:
+ - Broadway has been ported to GSK
+ - Only Unix domain sockets are supported now (we are passing fds to upload textures)
+
+* GSK:
+ - We use cached textures for icons now
+ - We also use cached textures for symbolic icons, and recolor using a shader
+ - The glyph cache supports hi-dpi
+ - Some render node APIs have been tweaked: cairo, text, transform nodes
+ - GskRenderer::scale-factor and GskRenderer::viewport have been dropped
+ - gsk_render_node_set_scaling_filters has been dropped
+
+* GTK:
+ - A new event controller, GtkEventControllerMotion, is intended to replace
+   most remaining uses of ::motion-notify-event
+ - New APIS: gtk_widget_contains and gtk_widget_pick
+ - gtk_widget_get_content_size has been replaced by gtk_widget_get_width/height
+ - The GtkWidget:parent-set signal has been dropped
+ - GtkHeaderBar::show-close-button has been renamed to ::show-title-buttons
+ - GtkFontButton::font-name has been replaced by GtkFontChooser::font
+ - The GtkTextTag::event signal has been dropped
+ - The text buffer serialization API has been removed
+ - We longer install 'semi-private' headers like gtktextlayout.h or gtktextdisplay.h
+ - gtk_application_is_inhibited has been dropped
+
+* Theming:
+ - Focus rendering has been changed. Outlines are always rendered now, and
+   we set the :focus and :focus(visible) pseudo-classes on elements to allow
+   the theme control over where to render focus rectangles
+ - The font-feature-settings CSS property is supported
+ - The -gtk-icon-size custom CSS property allows theme control of icon sizes
+
+* Emoji:
+ - We support Ctrl-. and Ctrl-; to pop up the Emoji chooser
+ - The Emoji chooser is also available in GtkTextView
+ - We avoid overly wide fallback rendering with some EmojiOne fonts
+
+* GtkInspector:
+ - The inspector shows more render node details
+ - The UI has been slightly reorganized
