+1 to this. Since the tentative date for PY 3.9 deprecation is nearing (Oct 2025), since we support 3.10 (relatively easier migration), I do not see why we should delay the support here.
Maintaining older versions is a nightmare in itself and becomes even more so with the combinations we have in Airflow. Waiting till the last day could also lead to surprises which might give us a hard time. Thanks & Regards, Amogh Desai On Sun, Jun 22, 2025 at 3:20 PM Jarek Potiuk <ja...@potiuk.com> wrote: > +1.
