python version support

Are there known compatibility issues with python 3.6? In my use I haven't ran into any issues, but have not thoroughly tested.

prog_models/setup.py

Line 40 in 44c4524

python_requires='>=3.7, <3.11',

Python3.6 is depreciated, so according to our security policy, we can no longer support it.

That said, there are no known issues, but we no longer test with 3.6, so I can't say for sure

Got it. I also just realized I was using an old environment. Thanks!
