This is quite amazing. Thanks to everyone involved for the great work, and especially Massimo for masterfully co-ordinating everything without breaking backward compatibility
Small remark: (posted it in another thread, but repeating here in case it was not visible enough) request.utcnow is mentioned in the changelog here and in the README, but is not in the most recent "hg pull -u" that I did this morning. So either the README/changelog is wrong, or there is a patch that went missing somewhere.
