@ethanfurman - Apologies for being late but I am not seeing these changes reflected at docs.python.org. Should I expect to see them there?

[ethanfurman]

I just checked the 3.11 docs and the 3.14 docs and see the changes.-- where exactly were you looking?

@ethanfurman - See https://docs.python.org/3.11/library/enum.html#module-enum
