cfl-lint v0.59.0 README and CONTRIBUTING say it supports python v3.5+ (setup.py says python 3.6+).

However, aws-sam-translator has dropped support for python v3.6 since version 1.43.0.
As far as I can tell, it hasn't supported python v3.5 at any point, the first v3+ support was in 1.20.0, which started with python v3.6, but I haven't looked too hard at its support for v3.5.

We no longer are supporting Python 3.6. You can pin some older versions of SAM and cfn-lint. You'll also still be able to run cfn-lint --update-specs to keep it up to date.
