**IMPORTANT PACKAGING NOTE**

Starting with this version, the ``setup_requires`` argument was dropped from ``setup.py`` in favor of
``build-system.requires`` in ``pyproject.toml`` . This means that for correctly building or installing from sdist,
you will need to use a PEP517/PEP518 compliant tool (tox>=3.3.0, setuptools>=40, pip>=10.0, pep517.build) or manually
install the build requirements yourself (just ``setuptools`` and ``setuptools-scm``, for now).

Additionally, for correct package version detection, a full git checkout is required when building (this was always the
case). Building without ``.git`` or without ``setuptools-scm`` will result in a distribution with a version like
``drf-yasg-1!0.0.0.dev0+noscm.00000167d19bd859``.
