ActiveState security release of setuptools for Python 3.9. Upstream 83.0.0 and later require Python >= 3.10. This release is 82.0.1 plus the upstream security fix.

Security

  • CVE-2026-59890 / GHSA-h35f-9h28-mq5c (medium): MANIFEST.in matching now ignores Unicode normalization form (NFC vs NFD). Before this fix, an exclude, global-exclude, recursive-exclude or prune rule could fail to drop a non-ASCII-named file stored NFD on disk (as on macOS APFS/HFS+), so the excluded file was published in the sdist. Backport of pypa/setuptools@dd9f436a3 (released in v83.0.0).
