Error with pytest==4.1.0

Hello,

I've just upgraded to pytest==4.1.0 today and I'm getting an error with pytest-benchmark==3.1.1:

If I downgrade back to pytest==4.0.2 there is no error.

I'm on Python 3.7 on macOS

Looks like this may be the cause:
pytest-dev/pytest/issues/3078
pytest-dev/pytest/pull/4542

This error is mentioned in #124 and already fixed pending a new release of pytest-benchmark.

Oops - sorry, didn't see that one - closing

3.2.0 was just released.

Awesome - thank you - just tested and it works well for me again :)
