I just released version 0.7.1 of #rsop, a stateless #OpenPGP ("SOP") CLI tool based on @rpgp:
https://crates.io/crates/rsop/
This version adds support for the "merge-certs" SOP command, which consolidates multiple versions of a certificate into a unified aggregate view.
For more on #SOP, see https://datatracker.ietf.org/doc/draft-dkg-openpgp-stateless-cli/
