I don’t know about it at a higher level, but the end of the first video of the Blender Guru donut tutorial series for 2.8 involved setting the monkey head on fire, and the instructions were broken by 2.92: what was described would no longer do anything—some kind of baking needed to be invoked manually. That was a part of what made me decide to wait until it was updated. (The other part was that my Surface Book could only barely reach 2fps for something that simple.)
