GTK+ 3.89.2 comes just one month after the first development snapshot, versioned 3.89.1, and it looks like it comes with a new Vulkan implementation that was added in parallel to the OpenGL one, CSS border-spacing support for the GtkBox and GtkGrid widgets, as well as the gadgets, and a working gtk4-icon-browser. Other than that, the gtk-demo component was updated to offer an example for using the PangoTabArray function with the GtkTextView widget, the GtkListBox and GtkFlowBox widgets were changed to no longer emit the “::selected-children-changed” signal during destruction, ad gtk-encode symbolic now supports icons that contain dots in their names.
