python-fido2 0.9.0

WARNING: Backwards-incompatible changes!

Version 0.9.0 (released 2021-01-20)

• Server: Attestation is now done in two parts (to align better with the spec):
  First, type-specific validation is done to provide a trust chain.
  Second, validation of the trust chain is done.
• Client: API changes to better support extensions.
  • Fido2Client can be configured with Ctap2Extensions to support.
  • Client.make_credential now returns a AuthenticatorAttestationResponse,
    which holds the AttestationObject and ClientData, as well as any client
    extension results for the credential.
  • Client.get_assertion now returns an AssertionSelection object, which is
    used to select between multiple assertions, resulting in an
    AuthenticatorAssertionResponse, which holds the ClientData, assertion
    values, as well as any client extension results for the assertion.
• Renames: The CTAP1 and CTAP2 classes have been renamed to Ctap1 and Ctap2,
  respectively. The old names currently work, but will be removed in the
  future.
• ClientPin: The ClientPin API has been restructured to support multiple PIN
  protocols, UV tokens, and token permissions.
• CTAP 2.1 PRE: Several new features have been added for CTAP 2.1, including
  Credential Management, Bio Enrollment, Large Blobs, and Authenticator Config.
