From GitHub Actions log:

I can reproduce locally (clean 3.12 pyenv virtualenv, with requirements*.txt installed):

This is fun:

• importlib.resources.read_text() gives a DeprecationWarning in 3.12
• The suggested solution using importlib.resources.files() etc. is only usable from 3.9...
• But we still support 3.8

💩

[mikegerber]

4047f8b fixes this by using the backports in PyPI's importlib_resources + the recommended files().joinpath().read_text() method.

👀 @kba @bertsky This might come up elsewhere when on Python 3.12

Reopening: needs new release.

(Not sure why this didn't come up with my earlier tests on Python 3.12 - might be a setuptools update that caused this.)
