In brief, UvToObject now syncs selections, the starfield shader got anti-alias filtering implemented, and ThingsOnSurface got a random rotation setting. See Changelog.
I had to change some things breaking backward compatibility for these shaders. Therefore old scenes will need some adjustment.
Starfield shader suffers from discontinuities at the borders of the texture area. Eventually, I will try a remedy by calculating the shader output from 3D ray directions without going to texture space.
