Up-to-DateUseful for checking your recent changes. For example, I changed the Old Burying Ground to being a cemetery. Below, you can see it with and without up-to-date.
Just drag the map anywhere you want, and click "Up-to-Date". Should work on any OSM map. You can click multiple times: clicking again will reload from the server.
