user6707: How do I find out what version Protocol specification is describing?

user18303: There's now a good overview at https://bitcoin.org/en/developer-reference#protocol-versions. The latest as of March 2014 is 70002.

user208: As of october 2013, the protocol version is 70001. It's not linked anymore to client versions (so it doesn't correspond to version 0.7.0.1 in particular; 70001 was introduced in 0.8.0), and is intended to go up in increments of one, as changes specified in BIPs are implemented.
