The migration is almost done, at least the rest should happen in the background. There are still a few technical difference between the old cluster and the new ones, and they are summarized in this issue. Please pay attention to the TL:DR at the end of the comment.
The new text describes how
behave.
Sway 1.9 flipped the behavior of 90 degree and 270 degree set_buffer_transform requests. mpv also changed the behavior of its vo_wayland_dmabuf backend which makes it only work correctly on sway 1.9.
It seems that the previous text was open to interpretation or at least caused some amount of confusion.
Consider the following example:
wl_output::transform = 90
.wl_surface::set_buffer_transform = 90
