multiple seconds, or even minutes. So disabled it for now.

+Overview of Changes in 4.15.0, 21-04-2024
 =========================================
 
-* GtkGraphicsOffload:
- - Don't crash without a child
+This release changes the default GSK renderer to be Vulkan, on
+Wayland. Other platforms still use ngl.
 
-* Icontheme:
- - Make symbolic svg loading more efficient
- - Handle color-free symbolics more efficiently
+The intent of this change is to get wider testing and verify that
+Vulkan drivers are good enough for us to rely on. If significant
+problems show up, we will revert this change for 4.16.
 
-* Accessibility:
- - Make the gtk-demo sidebar search more accessible
- - Stop emitting focus events
+You can still override the renderer choice using the GSK_RENDERER
+environment variable.
 
-* GDK:
- - Support XDG_ACTIVATION_TOKEN
- - dmabuf: Be more defensive when importing unknown formats to G
- - dmabuf: Use narrow range for YUV
+---
 
-* GSK:
- - gpu: Handle  tiny offscreens correctl
+This release also changes font rendering settings by introducing
+a new high-level gtk-font-rendering settings which gives GTK more
+freedom to decide on font rendering.
 
-* Build:
- - Fix many ubsan warning
+You can still use the low-level font-related settings by changing
+the new property to 'manual'.
 
-* macOS
- - Fix problems with events handed back to the OS
- - Respect GDK_DEBUG=default-settings
+---
 
-* Translation updates:
- German
- Indonesian
- Kabyle
- Korean
- Lithuanian
- Russian

-Overview of Changes in 4.14.3, 18-04-2024
-=========================================
+* GtkColumnView:
+ - Fix infinite loops in dispose
+ - Fix problems with weak ref cycles in GtkExpression
 
+* GtkListView:
 * GtkShortcutManager:
  - Track the propagation phase of added controllers
 
+* GtkGLArea:
+ - Produce dmabuf textures, so graphics offload is possible
+
+* GtkTextView:
+ - Support text shadows
+
+* GtkGraphicsOffload:
+ - Add a black-background property
+
+* Settings:
+ - Add a new gtk-font-rendering setting
+
 * Accessibility:
+ - Add support for GetRangeExtents to GtkAccessibleText
+ - Add support for GetOffsetAtPoint to GtkAccessibleText
  - Implement GtkAccessibleRange for scrollbars
 
+* GDK:
+ - Add a callback-based cursor API
+
+* GSK:
+-  Use the Vulkan renderer by default
+ - Avoid an infinite recursion with offscreens in some cases
+ - Optimize graphics offload to make it more likely that compositors
+   can use direct scanout
+
 * X11:
  - Fix some confusing debug messages
  - Drop a no-longer-relevant optimization that was interfering with
    getting the current window manager capabilities
 
+* macOS:
+ - Implement the color picker for macOS 10.15+
+
+* Debugging:
+ - Snow monitor resolution in the inspector
+
+* Demos:
+ - Use graphics offload in the shadertoy demo
+ - Show more reliable fps numbers in the fishbowl demo
+
 * Tools:
  - Support generating pdf in gtk4-rendernode-tool
 
+* Build:
+ - Require pango 1.52
+ - Require cairo 1.18
+ - Add a missing dependency that was causing build failures
