Will this require any changes to the games that use it or is it magic?

If the game works on wayland, then no, there won't be any changes required. That said, xonotic is now playable under pure wayland!

Another great recent SDL2 change: It now supports audio capture!

Excellent, this was the last thing preventing me from playing Xonotic under Wayland. Xonotic actually runs faster (!) for me under Wayland.

Games using mouse movements simulate relative mouse movements by calculating the distance to the center of the screen and then centering the cursor. Games utilizing the new mode can skip this and utilize relative coordinates directly.

yeah, when icculus wrote that tweet it was still in his own SDL dev fork, now it's in the official repo.
I hope the 2.0.5 release won't take as long as 2.0.4

Why the exclamation mark? Aside from not having X11's 'unfixable' security issues and general weirdness in the I/O path, higher efficiency was a major goal for Wayland. So assuming that the game runs without Xwayland, anything except speedups would be a disappointment …

Mir is still a thing? I thought Ubuntu would switch to Wayland by now.
