i am not a dev just a random user who check this

the smart uv it seems to do what always did, the mess that i see in the uv editor its simply fixable by doing Ctrl+A to average island size and Ctrl+P to arrange them inside the uv area or setting an island margin of 0.0001


What i see as a bug is that the smart uv is not arrange the uvs with an island marigin of 0.0, at least on this geometry with lots of loose parts

Looks like a bug to me, testing on e.g. the default monkey it will nicely pack islands inside the image, here they go outside for some reason.

I'm not sure if this is connected, but I have also seem to have noticed a huge slowdown from earlier versions while using this feature on larger meshes.
