Limitations (from the README)

[!WARNING] Upgrade note (v0.7.4) - federation wire format bumped from v2.0 to v2.1 (envelope-level nonce). v0.7.3 federation nodes are not compatible. Existing ~/.stellavault/federation/sharing.json files are not auto-downgraded to the safer defaults; review your myNodeLevel if you previously opted in.
