AWS powertools medium security documentation change

Service: powertools · 2026-01-07 · Security-related medium

File: powertools/python/latest/automation.md

Summary

Updated Python version support from 3.9-3.14 to 3.10-3.14 and removed Python 3.9 build steps

Security assessment

Dropping support for Python 3.9 likely addresses security concerns as older Python versions stop receiving security patches. This change prevents using vulnerable Python versions.
