Note: Generally, the "v3 era" refers to after the format change, i.e., RFC 8650 and higher. Time-wise, this was October 2019 and afterwards. (There exists one exception, which was not published in the v3 format -- RFC 8489, published February 2020. Its RFC number is intentionally lower than RFC 8650.)
