chore!: drop Python 3.9 support and update dependencies for security - #124
Merged
Conversation
Starlette (pulled in transitively via fastapi) never received patches for several known CVEs on any Python-3.9-compatible release line, so there is no way to remediate them while still supporting Python 3.9. Raising the minimum to Python 3.10 lets fastapi/starlette resolve to a patched release.
