[dependabot-preview]

Bumps setuptools from 43.0.0 to 46.0.0.

Changelog

Sourced from setuptools's changelog.

v46.0.0

• #65: Once again as in 3.0, removed the Features feature.
• #1890: Fix vendored dependencies so importing setuptools.extern.some_module gives the same object as setuptools._vendor.some_module. This makes Metadata picklable again.
• #1899: Test suite now fails on warnings.
• #2011: Fix broken link to distutils docs on package_data
• #1991: Include pkg_resources test data in sdist, so tests can be executed from it.

v45.3.0

• #1557: Deprecated eggsecutable scripts and updated docs.
• #1904: Update msvc.py to use CPython 3.8.0 mechanism to find msvc 14+

v45.2.0

• #1905: Fixed defect in _imp, introduced in 41.6.0 when the 'tests' directory is not present.

• #1941: Improve editable installs with PEP 518 build isolation:

  • The --user option is now always available. A warning is issued if the user site directory is not available.

  * The error shown when the install directory is not in PYTHONPATH has been turned into a warning.

• #1981: Setuptools now declares its tests and docs dependencies in metadata (extras).

• #1985: Add support for installing scripts in environments where bdist_wininst is missing (i.e. Python 3.9).

• #1968: Add flake8-2020 to check for misuse of sys.version or sys.version_info.

v45.1.0

• #1458: Add minimum sunset date and preamble to Python 2 warning.
• #1704: Set sys.argv[0] in setup script run by build_meta.__legacy__
• #1974: Add Python 3 Only Trove Classifier and remove universal wheel declaration for more complete transition from Python 2.

v45.0.0

• #1458: Drop support for Python 2. Setuptools now requires Python 3.5 or later. Install setuptools using pip >=9 or pin to Setuptools <45 to maintain 2.7 support.
• #1959: Fix for Python 4: replace unsafe six.PY3 with six.PY2

v44.0.0

• #1908: Drop support for Python 3.4.
