This version differs from our conda setup. I needed to get a newer version here to make it work with scikit build. But conda still only has 1.59.

We need to update to version 2...

Remind me how this gets the version now? Was it that code snipped we have in our __init__.py files?

The same as all other packages. It uses setuptools_scm which essentially runs the code here. Differently from the other projects, here, we write the version to src/scipp/_version.py to allow scikit-build to pick it up. (I don't know how this works in pure setuptools-based builds.) However, the actual scipp.__version__ is based on C++. There is some code in CMakeLists.txt - that I didn't touch - that also runs this git command and makes it so the version gets written into the binary. So the change here is only for the version reported in PyPI.

It uses setuptools_scm which essentially runs the code here.

Which code here? The file was removed.

This code you highlighted to query git.

So by "runs the code here", you do not mean the code here (which was deleted) but runs the same command?

Yes, or a similar one. It uses git to get the latest tag and extract a version from it. (We've been using it in our python-only projects. But without writing a _version.py file.)
