Overview of Changes in 4.16.0, 06-09-2024
=========================================

Note: This release changes the default GSK renderer to be Vulkan,
on Wayland. Other platforms still use ngl. The intent of this change
is to use the best available platform APIs. You can still override
the renderer choice using the GSK_RENDERER environment variable.

We believe that most of the problems reported with the new renderers
during the 4.13 and 4.15 development cycles have been addressed by now.

But the new renderers and dmabuf support are using graphics drivers
in different ways than the old gl renderer, and trigger new driver bugs.
Therefore, it is recommended to use the latest mesa release (24.2)
with the new renderers.
