* Cython 3.0 support.
* PR 3157 from mattmcdermott magnetic-analyzer-fix. Fixes bug briefly mentioned in 3070, where recent
spin property changes resulted in the `MagneticStructureEnumerator` failing. This is apparently due to
creating structures where only some `Species.spin` properties are defined, causing
CollinearMagneticStructureEnumerator` to fail.
* PR 3070 from mattmcdermott magnetic-enumerator-fix. To summarize: changes to default magnetic moments
introduced in 2727 now mean that structures with only partially defined magnetic moments (e.g., on
half the sites) cannot be successfully analyzed by `SpaceGroupAnalyzer`. This was encountered when
performing magnetic ordering enumeration, as the previous default behavior for `
MagOrderingTransformation` does not implicitly yield spins of 0 on the nonmagnetic sites. This has now
been fixed.
