Summary

Same root cause as PYTHON-5936. Dependabot opened PR #2927 to bump importlib-metadata from >=7.0 to >=9.0.0, but this cannot be adopted while PyMongo still supports Python 3.9.

Root cause

• importlib-metadata removed Python 3.9 compatibility in version 8.8.0; v9.0.0 is the major release incorporating that (and other breaking behavioral changes, e.g. raising MetadataNotFound/FileNotFoundError instead of returning None for missing metadata).
• PyMongo still targets Python 3.9: pyproject.toml sets requires-python = ">=3.9" and lists the Python :: 3.9 classifier.
• importlib-metadata is pinned in requirements/test.txt as importlib_metadata>=7.0;python_version < "3.13".

Because of this, importlib-metadata 8.8+ will not install on Python 3.9. Any Dependabot PR raising the lower bound to 8.8+/9.0+ cannot be merged until Python 3.9 support is removed.

Action

Ignore/hold this Dependabot update for now. Once PyMongo drops Python 3.9 support, we can accept the newer importlib-metadata version and raise the lower bound accordingly.
