Nice fixes. Things of note in my experience of great improvement:
- Mesh, go and collection 3D views load much faster and seem more stable
- The html build started working for my project? Im not looking a gift horse in the mouth. brilliant.
- The instancing is pretty neat. well done!
- Shaders seem better too. I was getting some odd warnings and now they are gone. nice.
Overall, this is a big jump in improvements. well done all. impressive.
