At the moment it uses the monthly data dump, planet.osm, so currently it's 
about a month out of date (as the data dump happens at the start of the 
However, from sometime next week it is likely to be used as the main 
renderer so will accurately reflect the current state of the OSM database.
One caveat: it does not render ways at the moment. This is because the SQL 
for getting ways from the database leads to prohibitively slow rendering, 
though Steve and others are working on this so it is likely to be a 
temporary problem.
As a quick fix, next time I grab planet.osm I will parse the ways and set 
each way's constituent segments to have the same tags as the parent way.
