I'm still seeing this issue on Python 3.9 - see https://github.com/hamcrest/PyHamcrest/actions/runs/5572367557/jobs/10178331294#step:5:234

Thanks Simon for the report.
I see you are using towncrier==23.6.0

The fix was merged in trunk but was not yet released.
You can give it a try by installing from git...

And I guess that since this issue is quite annoying, we should look at doing a new release.

Wanna maybe merge the Incremental thing and do a release? Would be a good meta cleanup release.

[adiroiban]

it would be nice to have the incremental + metalib PR in a release... but I think that we can do a release any time...so we can release now... and have another release once they are merged
