If I recall correctly, potlatch, the online editor save a new version of the way, and potentially all nodes within it, if any part of the way is modified... In this case, only changes to node positions occurred between the second and third versions being saved...<br> Specifically, this node <a href="http://www.openstreetmap.org/api/0.5/node/252528351/history" target="_blank">http://www.openstreetmap.org/api/0.5/node/252528351/history</a><br><br>d <br></div></div> <br></blockquote></div><br>ah, now I understand. Is this behaviour still in the actual versions? It creates lots of history-data for ways that didn't change (just for moving 1 node the whole way is resaved, which itself doesn't even differ, imagine this for a big way with some hundred nodes).<br></blockquote></div><br><div><br></div><div><div>I was thinking the other day that it might be nice to update the history page on the site [1] so that it gives more information about changes that occured, i.e. colouring new tags green, showing deleted tags crossed out, that sort of thing. I might have a go at doing that sometime unless someone else was planning on it. What do people think about this idea?</div><div><br></div><div>John</div><div><br></div><div>1 - <a href="http://www.openstreetmap.org/browse/way/23322317/history">http://www.openstreetmap.org/browse/way/23322317/history</a></div></div></body></html>
