 to the Git repository and open a new merge request, to let the GTK

-Overview of Changes in 4.15.0, 21-04-2024
-=========================================
-
-This release changes the default GSK renderer to be Vulkan, on
-Wayland. Other platforms still use ngl.

-
----
-
-This release also changes font rendering settings by introducing
-a new high-level gtk-font-rendering settings which gives GTK more

-Overview of Changes in 4.14.0, 12-03-2024
-=========================================
-
-Note: The new renderers and dmabuf support are using graphics drivers

-Overview of Changes in 4.13.6, 25-01-2024
-=========================================
-
-This release changes the ngl renderer to be the default renderer.

-the new renderers are production-ready. If significant problems
-show up, we will revert this change for 4.14.
-
-You can still override the renderer choice using the GSK_RENDERER
-environment variable.
-
-Since ngl can handle fractional scaling much better than the old gl
-renderer, we allow fractional scaling by default with gl now. If you
-are using the old gl renderer (e.g. because your system is limited to
-GLES2), you can disable fractional scaling by setting the GDK_DEBUG

-Overview of Changes in 4.13.5, 07-01-2024
-=========================================
-
-This release adds two new GSK renderers called vulkan and ngl,
-that are built from the same sources. The new renderers can
-handle many corner cases correctly that the current gl renderer
-does not handle, and they offer advantages such as antialiasing
-and supersampled gradients.
-
-The new renderers are still considered experimental, and GTK
-will only use them if they are explicitly selected using the
-GSK_RENDERER environment variable.
-
-As part of this work, the GSK include files have been rearranged.
-It is no longer necessary to include renderer-specific headers for
-ngl and vulkan (and doing so will trigger deprecation warnings),
-and their constructors are always available.
-
-The previously available experimental GdkVulkanContext APIs and
-the old Vulkan renderer have been removed.
-
-Vulkan is now enabled by default, and Linux distributions should
-build GTK with Vulkan support. This requires the glslc shader
-compiler as a new dependency.
-
-Vulkan is now also used for dmabuf support.
-
-* GtkDropdown:
- - Fix display of initial selection
-
-* GtkShortcutsWindow:
- - Make the window adapt to smaller screen widths
-
-* GtkTextView:
- - Fix a possible NULL dereference in history
-
-* GDK:
- - Make the png loader safer against overflows
-
-* GL:
- - Fix some errors in handling of texture formats and mipmaps
-
-
-Overview of Changes in 4.13.4, 30-12-2023

-
-* Input:

- - Fix crossing event generation for enter/leave
-
-* Wayland:

- - Be more careful when loading cursors
-
-* Dmabuf:
- - Add support for all Dmabuf formats
- - Tweak the offload code a bit, allow offloading translucent
-   textures, as long as they are raised. Decline to offload
-   with fractional scales.
-
-* Accessibility:
- - Add a few more accessible roles
-
-* GL:
- - Use GLES by default
- - Tweak GDK_DEBUG values. The new values are

-   The gl-legacy and nograbs values have been dropped.
-
-* Css:
- - Reduce memory consumption during theme loading
- - Fix opacity handling
-
-* Theme:
- - Refresh some of the included symbolic icons
-
-* MacOs:
- - Silence secure-restore message

 Title: Cairo interaction
+----
 
 ## Functions to support using cairo
 
 [Cairo](http://cairographics.org) is a graphics library that supports vector
 graphics and image compositing that can be used with GTK.
 
-GDK does not wrap the Cairo API and it is not possible to use cairo directly
-to draw on a [class@Gdk.Surface]. You can either use a
-[GtkDrawingArea](../gtk4/class.DrawingArea.html) widget or
-[gtk_snapshot_append_cairo](../gtk4/func.Snapshot.append_cairo.html)
-for drawing with cairo in a GTK4 application.
+GDK does not wrap the Cairo API; instead it allows to create Cairo
+drawing contexts which can be used to draw on [class@Gdk.Surface]s.
 
 Additional functions allow use [struct@Gdk.Rectangle]s with Cairo
 and to use [struct@Gdk.RGBA], `GdkPixbuf`, and [class@Gdk.Surface]

 The first is a reference to a color defined via a @define-color rule in CSS.
 The syntax for @define-color rules is as follows:
 
 ```

+@define-color Name Color
 ```
 
 To refer to the color defined by a @define-color rule, prefix the name with @.
 
-The standard CSS mechanisms that should be used instead of @define-color are
-custom properties, :root and var().
-
 GTK also supports color expressions, which allow colors to be transformed to
 new ones. Color expressions can be nested, providing a rich language to
 define colors. Color expressions resemble functions, taking 1 or more colors
 and in some cases a number as arguments.
