PrusaSlicer 2.91 XY compensation
I just upgraded from PS 2.90 to 2.91. I had just done XY shrink tests with PS 2.90 and figured out how much % I need to use for compensation. Now first time using 2.91 I see something has changed. XY shrinkage compensation is now listed in "mm". WTF! Is this a typo in the interface or a whole new approach to XY compensation?

It happens to us all, especially as we get older 🙄
However you are mistaken, XY Size Compensation has always measured in mm since the Slic3r days, quite a few years now.

RE:
I think you are talking about different things.
Snuffle is correct that XY compensation (Print Settings>Advanced) has always been, and still is, configured in mm.
However filament Shrinkage which has both an XY and Z compensation (Filament>Advanced) is set as a percentage, and still is a percentage even in 2.9.2
So nothing has changed between these settings in the recent versions.
RE: PrusaSlicer 2.91 XY compensation
OK. I see I was on two different pages, confusing the 2 different xy compensations. As Snuffle says "It happens to us all, especially as we get older". I really wish it were not so!
I think I understand shrinkage compensation - although I need to now figure out where I went wrong because I did a test piece 475mm long and it came out 473. This calulated to .42%. I did a test using .42% and it came out perfect. Then I printed the real part and with I thought was .42% shrink compensation and it came out 1.2mm to long. Maybe I used XY size compensation in my confusion. I'll start over!
Now that I know there are two, how does XY size compensation differ from XY shrink compensation and how is it used?
