[dependabot-preview]

Bumps setuptools from 51.1.0.post20201221 to 54.2.0.

Changelog

Sourced from setuptools's changelog.

v54.2.0

Changes

• #2608: Added informative error message to PEP 517 build failures owing to an empty setup.py -- by layday

v54.1.3

No significant changes.

v54.1.2

Misc

• #2595: Reduced scope of dash deprecation warning to Setuptools/distutils only -- by melissa-kun-li

v54.1.1

Documentation changes

• #2584: Added sphinx-inline-tabs extension to allow for comparison of setup.py and its equivalent setup.cfg -- by amy-lei

Misc

• #2592: Made option keys in the [metadata] section of setup.cfg case-sensitive. Users having uppercase option spellings will get a warning suggesting to make them to lowercase -- by melissa-kun-li

v54.1.0

Changes

• #1608: Removed the conversion of dashes to underscores in the extras_require{.sourceCode} and data_files{.sourceCode} of setup.cfg{.sourceCode} to support the usage of dashes. Method will warn users when they use a dash-separated key which in the future will only allow an underscore. Note: the method performs the dash to underscore conversion to preserve compatibility, but future versions will no longer support it -- by melissa-kun-li

v54.0.0

Breaking Changes

• #2582: Simplified build-from-source story by providing bootstrapping metadata in a separate egg-info directory. Build requirements no longer include setuptools itself. Sdist once again includes the pyproject.toml. Project can no longer be installed from source on pip 19.x, but install from source is still supported on pip < 19 and pip >= 20 and install from wheel is still supported with pip >= 9.
