• [C++] Add LasHeader copy constructor with the ability to change the is_copc parameter
• [Python] Add LazReader and LazWriter support to python
• [Python] Add LazWriter support to python multiprocessing transform functions
• [C++] Add output operator (<<) overrides for classes with ToString methods

Removed

• [Python/C++] Removed PointCount and ChunkCount from LazWriter

Version 2.4.0

[2.4.0] - 2022-09-12

Added

• [Python] Generate stubs (.pyi) for the C++ bindings to provide typechecking in the IDE
• [Python] Add helper functions for multithreading COPC reads and transformations
• [Python/C++] Add GetMaxDepth() function to CopcReader

Changed

• [Python/C++] Point and Points objects no longer depend on an internal scale or offset. XYZ coordinates are stored as doubles internally, and converted into integers using scale and offset only when packing or unpacking. The Points::Pack() function now requires either a LasHeader or a scale/offset vector as arguments. The Point::Pack() function now requires a scale/offset vector as arguments. The Point and Points constructors no longer take a scale and offset vector as arguments.
