• Added new 16-bit complex types: ml_dtypes.complex32 (based on float16) and
  ml_dtypes.bcomplex32 (based on bfloat16) (#351).
• Added new 1-bit integer types: ml_dtypes.int1 and ml_dtypes.uint1.
• Added __format__ method to custom float, complex, and integer types
  (#341). Previously,
  formatting custom scalars (e.g. in f-strings) fell back to string formatting,
  which could truncate exponents or fail on numeric format specifiers.
• ml_dtypes.finfo and ml_dtypes.iinfo now allow passing an array object to
  their constructor (#350).
• Fixed equality comparison (==, !=) when comparing custom dtypes against
  incompatible types like strings or None.
• Dropped support for Python 3.9, which reached end-of-life in October 2025.
• Dropped support for Python 3.13 free-threading, because cibuildwheel dropped support.
• Dropped support for NumPy < 2.0.
• Added support for Python 3.15.
• Switched build system to scikit-build-core and CMake (#361).
• Updated Eigen dependency to v5.0.1.
