PR Review

Summary

This PR only bumps certifi from 2017.11.5 to 2022.12.7 in the package's runtime requirements.txt. The isolated certifi bump is not the immediate compatibility problem, but the PR is stale and the surrounding dependency set is already not installable with a modern resolver.

Findings

• Severity: Important
• Location: requirements.txt
• Problem: The proposed target, certifi==2022.12.7, is no longer current; PyPI reports certifi 2026.5.20 as latest. More importantly, the same requirements.txt already pins requests==2.20.0 with urllib3==1.26.5, while requests 2.20.0 requires urllib3<1.25.
• Why it matters: Merging this old certifi-only PR would not produce a validated or internally consistent runtime dependency set. It leaves the package install path broken and does not get the repo to a current security baseline.
• Suggested fix: Close this stale dependabot PR and replace it with a coordinated refresh of requests/urllib3/certifi plus package-install validation. If the project still needs Python 3.6 compatibility, choose versions that support that runtime explicitly.

Test / Verification Notes

I inspected the PR diff, requirements.txt, the Makefile packaging path, and unpack.py. A focused resolver check for requests==2.20.0 plus certifi==2022.12.7 succeeds if pip is allowed to choose a compatible urllib3, so the certifi bump itself is not conflicting. The full pip install --dry-run -r requirements.txt fails first on the old safe-extractor==0.0.9 source build under the host Python, and a focused check of the already-pinned pair requests==2.20.0 / urllib3==1.26.5 reports ResolutionImpossible because requests requires urllib3<1.25. I also checked PyPI metadata with pip index versions certifi, which reports 2026.5.20 as latest.

Overall Recommendation

Needs changes before merge.
