NumPy 2.0.0 introduces significant changes and improvements, including support for variable-length string dtype and float32 in fft functions.

Performance enhancements include accelerated sorting functions and macOS Accelerate support.

There are breaking changes to Python and C APIs, impacting backwards compatibility and the NumPy ABI.

Several Python API functions have been removed and replaced, with support for Python versions 3.9-3.12.

Deprecated functions like np.asfarray and np.Inf have been addressed, along with compatibility notes for loadtxt and genfromtxt encoding changes.

Experimental memory improvements, modifications in sorting functions behavior, and enhancements to np.solve when broadcasting have been implemented.

C API changes include new datetime functionality and const correctness for ufunc C API.

New C-API import functions have been added for more efficient NumPy C-API table importing.

Users are encouraged to report any bugs encountered with the new features for further improvements.
