Nobody uses X.509v2 certificates.  In the context of X.509, the
successor of 1 is effectively 3, there is no "2".

    Version 2 (ITU-T Recommendation X.509, Nov 1993

	Version 2 of the X.509 certificate was very short-lived and
	rarely used.  In fact, the Internet Engineering Task Force
	(IETF) did not turn version 2 of the certificate into a RFC
	standard whatsoever. [...]
