  • Updated supported Python runtimes to 3.11.18, 3.12.16, 3.13.18, 3.14.10, and 3.15.2 for CVE-2026-115557.
  • Added the required per-distro  versionsToBuild.txt  metadata for Bullseye, Bookworm, Noble, and Resolute. Verified official source/signature availability and validated the 3.14.10 and 3.15.2 SHA-256 hashes against Python.org.
  • EOL Python 3.9 was intentionally excluded.

Register the new Python patch releases for each runtime OS so image builds can locate and verify the corresponding source archives.
