SpiceyPy 8.3.0

[8.3.0] - 2026-10-11

Added

• Python 3.15 support: cp315 wheel builds, CI test matrix, and PyPI classifier (#575)
• PEP 561 py.typed marker and Typing :: Typed classifier so type checkers use spiceypy's annotations (#552)
• mypy type checking CI job and typecheck dependency group (#555)
• Top-level cyice functions now accept NumPy scalars and 0-d arrays (numeric and string) and dispatch them to the scalar _s implementations (#569) (#571)

Changed

• Refined type hints throughout spiceypy, callbacks, and support types for smoother mypy usage (#555)
• Zero-argument ctypes functions now declare empty argtypes rather than None (#555)
• Updated to cibuildwheel v4.3.1 for the final CPython 3.15.0 release
• Pyodide/wasm builds now use cibuildwheel's default Pyodide 314.0.x and pyodide-build versions instead of pinning 314.0.0 and pyodide-build 0.35.1; removed the ignored build-frontend and redundant skip Pyodide options
• Docs updated to PyScript 2026.7.3 (Pyodide 314.0.3)
• Various CI action pin updates (#565) (#566) (#567) (#568) (#570) (#572) (#573) (#574) (#577)

Fixed

• String-input cyice _v functions (str2et_v, utc2et_v, scencd_v, scs2e_v) segfaulted on 0-d or multi-dimensional arrays; they now raise ValueError (#571)
• cyice functions rejected np.str_ and bytes for string arguments with a TypeError due to Cython 3 exact-type checks (#571)
• Missing commas in cyice __all__ that merged "azlcpo_v"/"azlrec" and "reset"/"rpd" (#555)
• ekgc return type annotation had the tuple element order wrong (#555)
• Various typos in docstrings and docs (#555)
