tests fail with pytest 6

Attempting to rebuild python-babel 2.8.0 for Arch Linux without changes, but with a system pytest 6 package, I get the following error:

Fixed by #752. Would a 2.8.1 patch release help?

[eli-schwartz]

Yes please, if that would be convenient. :)

We are currently doing python 3.9 rebuilds (as of 2 days ago), so we need to have the fix ASAP. And it's more convenient to bump the version to 2.8.1 than to backport the fix.

@eli-schwartz 2.8.1 is now up on PyPI and as a tag in this repo. Sorry for the inconvenience and thanks for the bug report!

A 2.9.0 release with functional changes over 2.8.0 is also forthcoming – maybe not today but soon enough 😄
