Well, Merry Christmas. It looks like there was an update to Matter.js — and it was released on Christmas Eve. It's not just the release date that makes this special. The last update was over two years ago. But additionally, this line looks interesting...
Optimised performance up to ~30% boost vs.
0.14.2

30%... is that right?! That sounds huge!
It's certainly nice to see activity on this project again.
