setuptools version limit

[frenzymadness]

What is the reason to limit the version of setuptools to:

zope.interface/pyproject.toml

Line 6 in 7e0be48

requires = ["setuptools<74"]

It seems to me that it builds fine also with setuptools 74.1.3

The `setuptools` requirement comes from zopefoundation/meta#274 Many `zopefoundation` projects use `zc.buildout` to build test environments. Apparently, (see PR mentioned above), new `setuptools` versions tend to be incompatible with older `zc.buildout` versions. The `zc.buildout` maintenance is not very active; therefore, it can take significant time until a new version compatible with newer `setuptools` becomes available. I might be possible that `zope.interface` does not use itself `zc.buildout` for its testing. However, many parts (among them the `setuptools` requirement) are generated from a common base used for all `zopefoundation` projects.

I am using setuptools version 75.6 and getting setuptools version mismatch. To solve this I removed the setuptools version.

zc.buildout is nowadays tested against setuptools == 75.6.0 , so we could make it less strict in the template which will once show up here.

See zopefoundation/meta#292 for reference.

This limit on the setuptools requirement is only active when building the zope.interface package. It should be no problem to have a Python venv with setuptools 75 and still install zope.interface. But this depends on how you build or install it and especially whether that is in isolation or not. For example:

$ python3.13 -mvenv test
$ cd test
$ bin/pip install -U pip setuptools build
$ bin/pip freeze --all
build==1.2.2.post1
packaging==24.2
pip==24.3.1
pyproject_hooks==1.2.0
setuptools==75.6.0
$ bin/python -m build --no-isolation /path/to/zope.interface/
...
ERROR Missing dependencies:
	setuptools<74
