> One camp (Open) wants to move faster and break backward compatibility, the other (Libre) wants to move slower and maintain backwards compatibility There is no breaking of backward compatibility. The crypto-refresh draft and the LibrePGP draft are equally backward-compatible. See 'A Critique on “A Critique on the OpenPGP Updates”': * https://blog.pgpkeys.eu/critique-critique Both groups would create a new format (Libre = v5; crypto-refresh = v6). v4-only wouldn't be able to handle either new format, and newer software could presumably be told to create files in the older format. The Proton folks are choosing to support both v5 and v6: * https://github.com/ProtonMail/go-crypto/pull/182 As is the Thunderbird/RNP team: * https://github.com/rnpgp/rnp/commit/fdfc1f5bb11d439e35f3c855...
