Vector

The Vector library provides classes and utilities for representing 2D, 3D, and 4D vectors, primarily for scientific computing, especially within the Scikit-HEP ecosystem. It offers a NumPy-compatible interface for vector operations, with support for various backends including pure Python objects, NumPy arrays, Awkward Arrays, and Numba for JIT-compiled calculations. The current version is 1.8.0, and it maintains a regular release cadence with several minor versions released annually.
