Heya folks :)
We just deployed new code and I am really happy to tell you that the URL datatype is finally available now. Wohoooo! I heard the first properties with the URL datatype have already been created. Maybe someone can link them here. I hope you will be able to make good use of it. Please let me know of any issues you find.
Additionally we had to deploy a breaking change to the API. Most bots and other tools should already be fixed but there might be some left that need a small change. For more details about this please see this email by Daniel: http://lists.wikimedia.org/pipermail/wikidata-tech/2013-September/000296.htm...
