Update to a new upstream release of <code>python-setuptools</code> that is not completely compatible with previous releases. Most notably, pkg_resources module was removed. This is a breaking change and Fedora packages that use pkg_resources should use the [ https://docs.python.org/3/library/importlib.resources.html importlib.resources] and [ https://docs.python.org/3/library/importlib.metadata.html importlib.metadata] projects for common use cases. There might be other breaking changes. We estimate about ~130 Fedora Rawhide packages to fail to build due to this upgrade (as of March 2026), more packages might be affected if they use pkg_resources on runtime. A deprecated compatibility package <code>python-setuptools80</code> will be provided for packages that cannot migrate away from pkg_resources yet.
