v2024.9.17

• Emergency release to fix broken phase diagram plotting due to completely unnecessary refactoring. (Thanks @yang-ruoxi for fixing.)

v2024.9.10

💥 Breaking: NumPy/Cython integer type changed from np.long/np.int_ to int64 on Windows to align with NumPy 2.x, changing the default integer type to int64 on Windows 64-bit systems in favor of the platform-dependent np.int_ type.
Recommendation: Please explicitly declare dtype=np.int64 when initializing a NumPy array if it's passed to a Cythonized pymatgen function like find_points_in_spheres. You may also want to test downstream packages with NumPy 1.x on Windows in CI pipelines.
