These are snapshots taken from OSM on the date given, and rendered using osmarender. They're released under the CC-BY-SA 2.0 license.
The update PNGs are simply the pixel difference between two of the snapshot renderings, done using the GIMP.
I made an animated GIF of these too.
That's quite big though, so you might like to try the
bimonthly (as in twice)
or the monthly (if twice a month seems too racy for you).
