October 2025 performance summary for NVIDIA/warp: Completed a major internal API cleanup with a deprecation strategy, reorganizing sources into an internal _src layout, and fixed a syntax error in operator.py to stabilize releases. Implemented type system enhancements (copy constructors for vectors/matrices, cached type creation) and introduced wp.cast() for safe type reinterpretation. Hardened operator and transformation logic with scalar-left support, clearer error reporting, robust wp.transform() kwarg validation, and safer defaults. Removed deprecated public API (wp.matrix(pos, quat, scale)) and exposed Devicelike in the public API, accompanied by documentation updates to align public references. These changes improve maintainability, enable safer future API evolution, boost runtime type performance, and provide clearer guidance for users and developers.
