With release v1.1.2 or v1.1.3 we are encountering the exception below. This did not occur with v1.1.1.

environment:

pytest-flake8==1.1.3 flake8==4.0.1

It appears flake8 introduced this config item in v5.0 and the project spec is allowing flake8>=4.0.

This did not occur with v1.1.1.

I'm surprised there's any regression here. I'd aimed for there to be very little behavioral change in v1.1.2. Here's the diff: https://github.com/coherent-oss/pytest-flake8/compare/1.1.1...v1.1.2. 1.1.1 also allowed flake8 >= 4.

I see now that v1.1.3 introduce the change (https://github.com/coherent-oss/pytest-flake8/compare/v1.1.2...v1.1.3), with 472da173c3d42c33b3a623f6b3b67b6808f14bec being the relevant commit. There's no mention of that in the changelog. I'll get the changelog updated and bump the minimum version.
