Agreed parking lots were not rounded; josm was acting up for me, and of course approximate beats unmapped.  The geometry fixups on parking that you did look good and also the better alignment of landuse to parcel data.  (I do wonder if there is better local data than what is in MassGIS L3 parcels.)

The parking relation as lost in your updates, and I just put that back, along with surface/access.  (Surely the general public does not have a right to park, even if there aren't scary don't-be-parking signs.)

(If you're in the mood, more sidewalks could be drawn, but that's true of most places, not specifically here. :-)
