BIP 70 should not be updated continuously. Mimic the IETF, where new RFCs are produced as protocols are extended. Once published, an IETF RFC is considered static. That said, I think it is OK to be smart, and break the "static" rule a bit for significant BIP bugs, or harmless maintenance of links-to-resources. -- Jeff Garzik Bitcoin core developer and open source evangelist BitPay, Inc. https://bitpay.com/
