I ran into a little problem here with the latest beta from November 6th:
I have a rectangular flat box with many circles booleaned out (think metal sheet with ventilation holes).
Now I want to fillet the edges of the holes on one side only, but seem to be unable to select the edges.

Went back to the last Beta and had no problem whatsoever selecting those edges.

I'll test some more later but for now I'm back to the September Beta.

Cheers,

Tom
