Thanks! I don't think the failures are related to your changes, but I'll try to fix them on separate PR and then ask you to rebase on the updated main first so we don't get a mangled release.

Thank you, @jameskermode.
I am assuming the build errors have something to do with f90wrap.

I changed the upper bound of f90wrap to use a version that precedes the current public commit 694dc9c. QUIP gets built, but it fails on the tests. So, I'm adding an upper bound for numpy as well.

Thanks, yes, this is likely what's needed. Numpy 2 will break a lot of builds.

The remaining test failures are due to a recent change in ASE. I'll push a fix for them shortly then we can get this merged.
