The renames actually misrepresent what those options are. The number of listings has not changed, so page 57 on the "Expiring Soon" sort has the same 29 days left listings. This is a non-solution to a legitimate concern of many lenders.
OK, so it's a bit cosmetic. There are no actual new sorts available. But if "Expiring Soon" is more meaningful to some people than "Old to New" perhaps they have added clarity to the site. It's not the change I would have implemented, but at least an effort is being made, and this one is very much on the fly, it seems. Further improvements can come when there's a chance to breathe.
