The Trove classifiers are missing entries for Python 3.13 and 3.14, which are stated as supported in the documentation and noxfile.py. According to the general rules, project metadata should be updated to reflect the supported versions when updating the minimum Python version.

  1. When updating the minimum supported Python version in runtime checks, ensure that the project's metadata in 'setup.py' or 'pyproject.toml' is also updated to reflect the same minimum version in 'python_requires' and Trove classifiers.
