What exactly changed in Bambu Studio v2.x.x?

I was printing the part below out of Hatchbox ABS on my P1S with textured PEI plate with the hexagonal face down using normal (auto) supports with the same ABS material for all support and interface with absolutely no problems before I updated to v2 BS. Now since the update I have had nothing but problems with the support material sticking to the finished face. I have gone through over 20 different setting changes in both the support structure and filaments settings and cannot replicate the quality I had before the update. Does anyone know exactly what changed in the latest update? I know the supports changed to tree, but were other settings effected? I’m beginning to suspect the custom filament settings may have also been affected.

On a separate topic, does anyone know how the slicer using the two settings I have red arrows by?

Yep, I think something is wrong with version 2 and/or the printer firmware also. I’ve been having problems with TPU that I never saw before the “upgrade”. Come to think of it, my last PLA print was wanky too. Too shinny like the temperature wasn’t hot enough. I’ve come to like the frosted look on most prints and try to keep my temps elevated. And I for sure don’t like the fan blasting at 100%. It’s loud!

As far as the settings, I think the “Recommended nozzle temperature” is just that. It’s a recommendation for the selected filament for documentation only. “Nozzle” is the actual target temperature the printer will try to maintain during the print.
