When installing Sequoia sq ( v0.29), I checked the version after the install and saw, sq 0.29.0 (sequoia-openpgp 1.14.0, using Nettle 3.8 (Cv448: true)). Not wanting to assume anything, but how does one activate the cv448 ECC curve? I see cv448 mentioned a lot especially in the "justus/ocb" branch. Thanks Paul
