A list of ways doesn't mean very much, is it possible to see a before and after map?

I understand you question as "I just updated the map and wish to compare with the state before", is this correct? If so, upon finishing editing online, when you switch back to the normal mapview you still should see the previous state. This is because the servers need some time to update. So, by switching between normal map view and the online editor, you definitely can compare. Then if you want to keep a record, get a copy, or an export, of this "old current" map, and wait tomorrow, you'll get the new one ;-)

@Herve5 Well no actually, I was wanting to see all the changes made since the beginning. Seeing ways move / get added / deleted.

I can't think of an easy way to do it online. Offline, you could use something like Maperitive to render "before" and "after" maps, or load "before" and then "after" .osm files for a small area into JOSM.

Of course, if you had a time machine you could go back to 2008 when the main Mapnik map only updated every week or so!

Actually - thinking about it - you might be able to use the cycle map as a "before" image, as that is updated less frequently than the others on the main site.

@SomeoneElse How would I render old data?
