Anyone else get a ton of space back after updating to 15.2?

Just wondering—I've had 15.2 installed for a few days on my M1 Macbook Air, and I just noticed that I now have about 60GB more space than I did before. I always regret having only gotten the 256GB hard drive because I'm constantly fighting to make room on it, so getting this much to work with seems miraculous. I actually freaked out a little and assumed I'd accidentally deleted some enormous folder, but as far as I can tell, everything is still there. Has this amount of space reclamation been the norm for you folks? I'm used to getting *some* back on major updates, but nothing even close to this. (Note: I did *not* activate any of the Intelligence stuff; just not interested.)
