I’ve always been mystified at the strange instructions for upgrading WordPress — “update all the files, except for …”. With more recent versions this gets easier because it’s possible to move

out of the main WordPress directory. Thus an upgrade of core WordPress doesn’t have a chance to modify the files that shouldn’t be modified.
