• The minimum version of the setuptools-scm build dependency has been
  set to 7. The Git archives are now produced by it natively, instead of
  relying on a third party plugin which is no longer being used.

  -- by @serhii73

  Related issues and pull requests on GitHub: Use setuptools-scm v7+ for building the dists #628.

• The packaging metadata has been migrated to the pyproject.toml-based
  621 declaration -- by @jaraco and @webknjaz.

  As a part of this update, the minimum version of the setuptools
  build backend was bumped to 61.2. Moreover, any compatibility shims
  that existed in setup.cfg and setup.py have been removed for good.

  Related issues and pull requests on GitHub: 📝 Switch packaging metadata to use PEP 621 #690.

Contributor-facing changes

• The test infrastructure has been updated to stop using the
  pytest-forked plugin -- by @jaraco and @webknjaz.

  This plugin was causing problems with upgrading to modern versions of
  Pytest and it is not going to be fixed anytime soon.

  It was used in a test that interacts with the system resource limits
  under *NIX environments in hopes to isolate the side effects caused
  by the preparatory code.

  It is possible that this will have an effect on the test sessions and
  we may have to look for alternative solutions for test process
  isolation.

  Related issues and pull requests on GitHub: Pytest 7: test_high_number_of_file_descriptors causes next test to fail #502, test_tls_client_auth: previous item was not torn down properly #511, Tests failing when building locally (in typeguard) #680,
  Disable forked and unpin pytest #681, 🧪 Stop using pytest-forked #703.

• The test infrastructure has been updated to start using the upstream
  reusable workflow reusable-tox.yml from tox-dev/workflow -- by
  @webknjaz.

  This chance allows us to de-duplicate the commonly used CI shape.

  Related issues and pull requests on GitHub: 🧪 Use reusable-tox.yml @ tox-dev/workflow #743.
