Changelog

Sourced from setuptools's changelog.

v78.1.0

Features

• Restore access to _get_vc_env with a warning. (#4874)

v78.0.2

Bugfixes

• Postponed removals of deprecated dash-separated and uppercase fields in setup.cfg. All packages with deprecated configurations are advised to move before 2026. (#4911)

v78.0.1

Misc

• #4909

v78.0.0

Bugfixes

• Reverted distutils changes that broke the monkey patching of command classes. (#4902)

Deprecations and Removals

• Setuptools no longer accepts options containing uppercase or dash characters in setup.cfg. Please ensure to write the options in setup.cfg using the :wiki:lower_snake_case <Snake_case> convention (e.g. Name => name, install-requires => install_requires). This is a follow-up on deprecations introduced in v54.1.0 <https://setuptools.pypa.io/en/latest/history.html#v54-1-0>_ (see #1608) and v54.1.1 <https://setuptools.pypa.io/en/latest/history.html#v54-1-1>_ (see #2592).

  .. note:: This change does not affect configurations in pyproject.toml (which uses the :wiki:lower-kebab-case <Letter_case#Kebab_case> convention following the precedent set in :pep:517/:pep:518). (#4870)
