Version 1.1.3 (released 2024-03-13)
Fix USB HID issue on MacOS that sometimes caused a pause while waiting for a timeout.
Fix argument to CredProp extension where an enum value was required instead of also allowing a string.
Fix parsing of some key types (ES384, ES512) causing signature verification to fail.
Deprecation: Calling websafe_decode with a bytes argument instead of str. This will raise a TypeError in the next major version of the library.
Version 1.1.2 (released 2023-07-06)
Fix ClientPin usage for Authenticators that do not support passing a PIN.
Fix: Handle correct CTAP response codes in authenticatorSelection.
Version 1.1.1 (released 2023-04-05)
Add community provided support for NetBSD.
Bugfix: Don’t set length for largeBlob when offset is 0.
Bugfix: Remove print statement in webauthn parsing.
Version 1.1.0 (released 2022-10-17)
Bugfix: Fix name of "crossOrigin" in CollectedClientData.create().
Bugfix: Some incorrect type hints in the MDS3 classes were fixed.
Stricter checking of dataclass field types.
Add support for JSON-serialization of WebAuthn data classes. This changes the objects dict representation to align with new additions in the WebAuthn specification. As this may break compatibility, the new behavior requires explicit opt-in until python-fido2 2.0 is released.
Update server example to use JSON serialization.
Server: Add support for passing RegistrationResponse/AuthenticationResponse (or their deserialized JSON data) to register_complete/authenticate_complete.
Add new "hybrid" AuthenticatorTransport.
Add new AuthenticatorData flags, and use 2-letter names as in the WebAuthn spec (long names are still available as aliases).

Several CTAP 2.1 features have been implemented.
Version 0.9.3 (released 2021-11-09)
Bugfix: Linux - Don’t fail device discovery when hidraw doesn’t support HIDIOCGRAWUNIQ (Linux kernels before 5.6).

Remove the need for the uhid-freebsd dependency on FreeBSD.
Version 0.9.1 (released 2021-02-03)
Add new CTAP error codes and improve handling of unknown codes.
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.
HID: The platform specific HID code has been revamped and cleaned up.
Version 0.8.1 (released 2019-11-25)

RelyingParty has been replaced with PublicKeyCredentialRpEntity, and name is no longer optional.
Options returned by register_begin/authenticate_begin now omit unspecified values if they are optional, instead of filling in default values.
Fido2Server.allowed_algorithms now contains a list of PublicKeyCredentialParameters instead of algorithm identifiers.
Fido2Server.timeout is now in ms and of type int.
Support native WebAuthn API on Windows through WindowsClient.
