charex 0.5.1

charex 0.5.1

charex 0.5.1 is a maintenance release for the Numba 0.65.1 compatibility
line. It includes the fixed-width scalar broadcasting parity fix layered after
0.5.0 and prepares the project for PyPI publication as charex-numba.

Compatibility

• Python >=3.10,<3.15
• Numba >=0.65.1,<0.66
• NumPy supported/tested window: >=1.22,<1.27 or >=2.0,<2.5
• llvmlite 0.47.x

np.strings support is conditional on NumPy 2.x.

Highlights

• Fixes fixed-width S/U N-D array plus Python scalar broadcasting for
  np.char and np.strings comparisons and occurrence methods.
• Keeps the public API import-only: import charex registers the overloads.
• Moves implementation modules under private charex._* names.
• Moves tests and benchmarks out of the installable charex package namespace.
• Prepares the PyPI distribution as charex-numba while preserving the import
  package name charex.
• Adds PyPI metadata and source-archive manifest rules for cleaner release
  artifacts.

Not In Scope

• New string operations beyond the 0.5.0 read-only catalog.
• Fresh benchmark artifacts.
• Transformation/output-producing operations such as replace, case conversion,
  strip, pad, join, split, encode, and decode.
