The protocol needs to be updated to the latest version of the spec at https://whispersystems.org/docs/specifications/doubleratchet/. Mostly this involves cleaning up the root key stuff and using hkdf instead of pbkdf2. Nothing in these changes affects the essential security of pyaxo.

Note that the AEAD requirement in the latest version of the spec is met by our recent switch to libsodium/pynacl.
