- Update to 4.2:
* Fall back to installing project's build backend in an isolated
environment if a compatible version isn't installed in the current env
* Fix metadata extraction failure when project ``long_description`` is
included as a header rather than a payload in the ``METADTA`` file
* Add a fallback to restore compatibility with Setuptools <61
* Add ``python_requires``, update classifiers, add implicit dependencies
and remove unused deps in Pyroma's own packaging metadata
* Moved from a custom trove classifiers list to using the
trove-classifiers package
* Support checking the Requires-Python metadata
* Silence noisy build backend output when building metadata
* Official support for Python 3.11
* Some string formatting bugs
* Now follows black and flake8 rules
* Check if author_email field contains author name
* The deprecation test for test_suite is no longer needed, as the patched
setuptools method of gathering metadata as a whole is deprecated.
* `description_content_type` also needs a mapping in the metadata map.
* Added support for PEP517 by using `build` to build the metadata as a
preferred build method over the old patched setuptools method.
* Add a deprecation for `test_suite`
* Fixed __getattr__-related crash in tests with python3.7
* Added support for pre-commit
* Rewrote parts of the PyPI support, to avoid using the xmlrpc API,
since it's being heavily rate-limited at the moment. Only one call
is using it now, which seems to work fine.
* Backwards incompatible change: As a result of the above change, when
looking for packages on PyPI, the package name must now be spelled
exactly correct, including capitalization.
