Changelog

[0.1.4] - 2025-04-03

Added

• Added the Frame class providing a framework for relativistic reference frame transformations [#1].

Frame Creation Methods:

• Frame.rest(): Create a stationary reference frame
• Frame.from_lvec(): Create a frame in which a specified Lorentz vector is at rest
• Frame.center_of_mass(): Create a center-of-mass frame from a collection of particles

Frame Transformation Methods:

• LVec.to_frame(): Transform a vector directly to a specified reference frame
• LVec.transform_frame(): Transform a vector between two explicit reference frames

Changed

• Extended README with information about reference frames features.

Changelog

[0.1.3] - 2025-03-23

Added

• Introduced 2D and 3D vector classes supporting NumPy and Awkward arrays.
• Added support for jagged Awkward arrays in vector operations.
• Implemented vector rotation methods in 2D and 3D.
• Introduced backend_tan for tangent computation.
• Added scalar input support to backend_log and backend_exp.
• Introduced compute_mass safeguard for negative mass squared.
• Added jagged array inner dimension consistency check in utilities.
• Added fine-grained caching system with performance instrumentation.
• Added LHCb-specific vector performance benchmarks.
• Added comprehensive benchmarking against the vector package and for LVec performance.
• Added requirements.txt file (generated via uv).
• Added pytest to development dependencies for uv run pytest.

Changed

• Updated Python requirement to 3.10+ due to numpy compatibility.
• Updated example documentation with real LHCb Open Data analysis.
• Extended README with 2D/3D support and installation instructions.
• Updated LHCb example to use internal to_np function instead of ak.to_numpy.
• Updated README to reflect LHCb benchmarks.
• Updated pyproject.toml with missing dependencies for awkward.

Fixed

• Corrected vector class names from LVec2D/LVec3D to Vector2D/Vector3D.
• Fixed multiple utilities and backend functions to better support scalar and jagged inputs.
• Improved robustness of compute_mass against invalid inputs.

Refactored

• Unified use of backend_where instead of np.where for consistency.
• Improved clarity in pseudorapidity calculation.
• Removed redundant np.atleast_1d calls in to_ak.
• Restructured caching logic for better modularity.

Removed

• Removed uproot from dependencies, as it is no longer required.
