#2259: Setuptools now provides a .pth file (except for editable installs of setuptools) to the target environment to ensure that when enabled, the setuptools-provided distutils is preferred before setuptools has been imported (and even if setuptools is never imported). Honors the SETUPTOOLS_USE_DISTUTILS environment variable.

#2232: In preparation for re-enabling a local copy of distutils, Setuptools now honors an environment variable, SETUPTOOLS_USE_DISTUTILS. If set to 'stdlib' (current default), distutils will be used from the standard library. If set to 'local' (default in a imminent backward-incompatible release), the local copy of distutils will be used.

#2137: Removed (private) pkg_resources.RequirementParseError, now replaced by packaging.requirements.InvalidRequirement. Kept the name for compatibility, but users should catch InvalidRequirement instead.

#2143: Setuptools adopts distutils from the Python 3.9 standard library and no longer depends on distutils in the standard library. When importing setuptools or setuptools.distutils_patch, Setuptools will expose its bundled version as a top-level distutils package (and unload any previously-imported top-level distutils package), retaining the expectation that distutils' objects are actually Setuptools objects. To avoid getting any legacy behavior from the standard library, projects are advised to always "import setuptools" prior to importing anything from distutils. This behavior happens by default when using pip install or pep517.build. Workflows that rely on setup.py (anything) will need to first ensure setuptools is imported. One way to achieve this behavior without modifying code is to invoke Python thus: python -c "import setuptools; exec(open('setup.py').read())" (anything).

Incorporate changes from v44.1.0:
#308: Allow version number normalization to be bypassed by wrapping in a 'setuptools.sic()' call.

#1756: Force metadata-version >= 1.2. when project urls are present.
#1769: Improve package_data check: ensure the dictionary values are lists/tuples of strings.
#1788: Changed compatibility fallback logic for html.unescape to avoid accessing HTMLParser.unescape when not necessary. HTMLParser.unescape is deprecated and will be removed in Python 3.9.

#1735: When parsing setup.cfg files, setuptools now requires the files to be encoded as UTF-8. Any other encoding will lead to a UnicodeDecodeError. This change removes support for specifying an encoding using a 'coding: ' directive in the header of the file, a feature that was introduces in 40.7. Given the recent release of the aforementioned feature, it is assumed that few if any projects are utilizing the feature to specify an encoding other than UTF-8.

#1652: Added the build_meta:__legacy__ backend, a "compatibility mode" PEP 517 backend that can be used as the default when build-backend is left unspecified in pyproject.toml.
#1635: Resource paths are passed to pkg_resources.resource_string and similar no longer accept paths that traverse parents, that begin with a leading /. Violations of this expectation raise DeprecationWarnings and will become errors. Additionally, any paths that are absolute on Windows are strictly disallowed and will raise ValueErrors.
#1536: setuptools will now automatically include licenses if setup.cfg contains a license_file attribute, unless this file is manually excluded inside MANIFEST.in.

#1519: In pkg_resources.normalize_path, additional path normalization is now performed to ensure path values to a directory is always the same, preventing false positives when checking scripts have a consistent prefix to set up on Windows.
#1545: Changed the warning class of all deprecation warnings; deprecation warning classes are no longer derived from DeprecationWarning and are thus visible by default.
#1554: build_meta.build_sdist now includes setup.py in source distributions by default.
#1576: Started monkey-patching get_metadata_version and read_pkg_file onto distutils.DistributionMetadata to retain the correct version on the PKG-INFO file in the (deprecated) upload command.
#1395: Changed Pyrex references to Cython in the documentation.
#1456: Documented that the rpmbuild packages is required for the bdist_rpm command.
