Benchmarking chardet 4.0.0 on CPython 3.7.5 (default, Sep  8 2020, 12:19:42)

~~~~~~~~~~~~~~~~

* **BACKWARDS INCOMPATIBLE:** Support for Python 3.5 has been removed due to
low usage and maintenance burden.
* **BACKWARDS INCOMPATIBLE:** The
:class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` and
:class:`~cryptography.hazmat.primitives.ciphers.aead.AESGCM` now require
64-bit to 1024-bit (8 byte to 128 byte) initialization vectors. This change
is to conform with an upcoming OpenSSL release that will no longer support
sizes outside this window.
* **BACKWARDS INCOMPATIBLE:** When deserializing asymmetric keys we now
raise ``ValueError`` rather than ``UnsupportedAlgorithm`` when an
unsupported cipher is used. This change is to conform with an upcoming
OpenSSL release that will no longer distinguish between error types.
* **BACKWARDS INCOMPATIBLE:** We no longer allow loading of finite field
Diffie-Hellman parameters of less than 512 bits in length. This change is to
conform with an upcoming OpenSSL release that no longer supports smaller
sizes. These keys were already wildly insecure and should not have been used
in any application outside of testing.
* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
OpenSSL 1.1.1i.
* Python 2 support is deprecated in ``cryptography``. This is the last release
that will support Python 2.
* Added the
:meth:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey.recover_data_from_signature`
function to
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey`
for recovering the signed data from an RSA signature.

.. _v3-2-1:

++++++++++++++++

- Python 2 is no longer supported (the 2.x branch supports Python 2,
use "idna<3" in your requirements file if you need Python 2 support)
- Support for V2 UTS 46 test vectors.

==================

Features
--------

- Support ``GenericAliases`` (``MultiDict[str]``) for Python 3.9+
`553 <https://github.com/aio-libs/multidict/issues/553>`_


Bugfixes
--------

- Synchronize the declared supported Python versions in ``setup.py`` with actually supported and tested ones.
`552 <https://github.com/aio-libs/multidict/issues/552>`_

-------------------------------------------------------------------------
Fixed
- Exclude Python cache files from PyPI releases.

Added
- Added new options to require certain claims
(require_nbf, require_iat, require_exp) and raise `MissingRequiredClaimError`
if they are not present.
- If `audience=` or `issuer=` is specified but the claim is not present,
`MissingRequiredClaimError` is now raised instead of `InvalidAudienceError`
and `InvalidIssuerError`

-------------------------------------------------------------------------
Fixed
- ECDSA (ES256, ES384, ES512) signatures are now being properly serialized [158][158]
- RSA-PSS (PS256, PS384, PS512) signatures now use the proper salt length for PSS padding. [163][163]

Added
- Added a new `jwt.get_unverified_header()` to parse and return the header portion of a token prior to signature verification.

Removed
- Python 3.2 is no longer a supported platform. This version of Python is
rarely used. Users affected by this should upgrade to 3.3+.

-------------------------------------------------------------------------

Fixed

- Update test dependencies with pinned ranges
- Fix pytest deprecation warnings

-------------------------------------------------------------------------

Changed

- Remove CRLF line endings [353][353]

Fixed

- Update usage.rst [360][360]

Added

- Support for Python 3.7 [375][375] [379][379] [384][384]
