Wow... there is a lot going on here for a single changeset. Too much IMO. It's hard to tell what all was done. The changeset comment doesn't really explain much either.

I noticed because you changed Pioneer Courthouse Square & Director Park by replacing highway=pedestrian & area=yes with area:highway=pedestrian.
The wiki says:

"Specifically, it is not the same as highway=pedestrian + area=yes, which represents a non-linear area, such as a square or plaza"

I saw a few other issues. The speed limit was removed from Willamette Greenway. I haven't been there for a while, but I think there were actually speed signs. There is at least one road with deprecated parking tags removed without the new tags being added. I'm also curious why the level tag was removed from rooms in PSU buildings.
