I think the most drastic change (from what I quickly saw), is deprecation of the x.real and x.imag attributes on complex numbers and arrays. I'm not sure if we use this syntax within this module, but it would be good to check all possible compatibility issues.
Recently, Numpy 2.0 was released, which introduces a lot of changes in its structure and available methods/functions.
See Numpy 2.0 release notes and their Migration Guide.
