Changed
~~~~~~~

Drop support for Python 2 and Python 3.0-3.5
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Python 3.5 is EOL so we decide to drop its support. Version ``1.7.1`` is
the last one supporting Python 3.0-3.5.

Require cryptography >= 3
^^^^^^^^^^^^^^^^^^^^^^^^^

Drop support for PyCrypto and ECDSA
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

We've kept this around for a long time, mostly for environments that
didn't allow installing cryptography.

Drop CLI
^^^^^^^^

Dropped the included cli entry point.

Improve typings
^^^^^^^^^^^^^^^

We no longer need to use mypy Python 2 compatibility mode (comments)

``jwt.encode(...)`` return type
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Tokens are returned as string instead of a byte string

Dropped deprecated errors
^^^^^^^^^^^^^^^^^^^^^^^^^

Removed ``ExpiredSignature``, ``InvalidAudience``, and
``InvalidIssuer``. Use ``ExpiredSignatureError``,
``InvalidAudienceError``, and ``InvalidIssuerError`` instead.

Dropped deprecated ``verify_expiration`` param in ``jwt.decode(...)``
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Use
``jwt.decode(encoded, key, algorithms=["HS256"], options={"verify_exp": False})``
instead.

Dropped deprecated ``verify`` param in ``jwt.decode(...)``
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Use ``jwt.decode(encoded, key, options={"verify_signature": False})``
instead.

Require explicit ``algorithms`` in ``jwt.decode(...)`` by default
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Example: ``jwt.decode(encoded, key, algorithms=["HS256"])``.

Dropped deprecated ``require_*`` options in ``jwt.decode(...)``
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

For example, instead of
``jwt.decode(encoded, key, algorithms=["HS256"], options={"require_exp": True})``,
use
``jwt.decode(encoded, key, algorithms=["HS256"], options={"require": ["exp"]})``.

And the old v1.x syntax
``jwt.decode(token, verify=False)``
is now:
``jwt.decode(jwt=token, key='secret', algorithms=['HS256'], options={"verify_signature": False})``

Added
~~~~~

Introduce better experience for JWKs
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Introduce ``PyJWK``, ``PyJWKSet``, and ``PyJWKClient``.

.. code:: python

    import jwt
    from jwt import PyJWKClient

    token = "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6Ik5FRTFRVVJCT1RNNE16STVSa0ZETlRZeE9UVTFNRGcyT0Rnd1EwVXpNVGsxUWpZeVJrUkZRdyJ9.eyJpc3MiOiJodHRwczovL2Rldi04N2V2eDlydS5hdXRoMC5jb20vIiwic3ViIjoiYVc0Q2NhNzl4UmVMV1V6MGFFMkg2a0QwTzNjWEJWdENAY2xpZW50cyIsImF1ZCI6Imh0dHBzOi8vZXhwZW5zZXMtYXBpIiwiaWF0IjoxNTcyMDA2OTU0LCJleHAiOjE1NzIwMDY5NjQsImF6cCI6ImFXNENjYTc5eFJlTFdVejBhRTJINmtEME8zY1hCVnRDIiwiZ3R5IjoiY2xpZW50LWNyZWRlbnRpYWxzIn0.PUxE7xn52aTCohGiWoSdMBZGiYAHwE5FYie0Y1qUT68IHSTXwXVd6hn02HTah6epvHHVKA2FqcFZ4GGv5VTHEvYpeggiiZMgbxFrmTEY0csL6VNkX1eaJGcuehwQCRBKRLL3zKmA5IKGy5GeUnIbpPHLHDxr-GXvgFzsdsyWlVQvPX2xjeaQ217r2PtxDeqjlf66UYl6oY6AqNS8DH3iryCvIfCcybRZkc_hdy-6ZMoKT6Piijvk_aXdm7-QQqKJFHLuEqrVSOuBqqiNfVrG27QzAPuPOxvfXTVLXL2jek5meH6n-VWgrBdoMFH93QEszEDowDAEhQPHVs0xj7SIzA"

    jwks_client = PyJWKClient(url)

        audience="https://expenses-api",
        options={"verify_exp": False},
    )
    print(data)

Support for JWKs containing ECDSA keys
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Add support for Ed25519 / EdDSA
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
