No.
What happened?
Oryx build for Python version 3.13 has worked for months, but now I am getting a failed remote build for Azure Functions with Oryx stating that only Python 3.10.x is supported.
What did you expect or want to happen?
I expected Oryx build on Azure to support platform version Python 3.13.
How can we reproduce it?
Try deploying an azure function app using oryx build for python 3.13
func azure functionapp publish insert-function-app-name
