Locally against cryptography 50.0.0 (OpenSSL 4.0.1) and, as a control, against the 49.0.0 minimum:
TestContext::test_fallback_default_verify_paths, reproduces identically on cryptography 49 — it needs system CA certs at OpenSSL's default path, which this sandbox lacks.

setup.py'slong_descriptionregex terminates on the first literal----line, which now lives at CHANGELOG.rst:499, so the PyPI "Release Information" section carries every release back to that point rather than just the newest.Generated by Claude Code
