sorry, we don't backport to releases prior to the latest minor version -- this has been released in 6.2.4

[erikkemperman]

Fair enough. I thought I’d give it a shot — I’m running into this bug with mypy’s unit tests, and I expect they will want to continue supporting python 3.5 and thus depend on pytest<6.2.0...

[asottile]

presumably you only need pytest<6.2.0 for python3.5 and can use modern pytest elsewhere?

[erikkemperman]

Yes, I think so. Disclaimer, I’m not a mypy developer, was just playing around with the 3.10 beta and wanted to try out some of the new typing features.

So I suppose mypy will have to split their test-requirements and only use the older pytest for older pythons.

Thanks for taking a look!
