Numpy are currently aiming to release Numpy 2 around the end of the December or in January (ref: numpy/numpy#24300). This is a tracking issue for various things we may need to do in order to support the new major release.

I'm likely to update this list as I/we find more things.

- [ ] #10305 
- [ ] #10890
- [ ] #10891
- [ ] #10892
- [ ] #10897
- [ ] Verify usage of Numpy C API via PyO3 / Rust's `numpy` crate
- [ ] Test against Numpy 2.0rc once released
- [ ] Release pin on `numpy<2` once we're building/testing against it (even as rc) 

I'm trying to get most of the deprecated usage squashed now. If we let a few more bits of deprecated behaviour slip in between now and the Numpy 2 release, it's not the end of the world, and hopefully the subtasks of this issue will point us to what needs to be fixed.
