This full packed release comes with three new staging protocols:
system bell - allowing e.g. terminal emulators to hand off system
bell alerts to the compositor for among other things accessibility
purposes
fifo - for implementing first in first out surface content update
behavior
commit timing - for adding time constraints to surface content
update
Other than this, the presentation timing protocol protocol got a version
minor bump describing how to deal with variable refresh rate.
Other protocols saw the regular clarifications and bug fixes, and some
deprecated events is now properly indicated as such in the XML. Please
see individual commits for details.
FIFO and commit timing are big for gaming. IIRC the lack of those protocols was a big reason why devs didn't want to enable Wayland support for SDL3 at first.
Sure but I think the core devs should focus on it. It is a big thing that is important (especially for a piece of always changing beta software like Wayland) yet still missing.
