Release 0.9.0 - Changelog

• Added native support for SPZ v4 in both input and output.
• Kept SPZ v3 as the default write target to preserve backward compatibility.
• Extended SH handling up to degree 4, with correct inference, trimming, and roundtrip behavior.
• Added --preserve_sh4 as an experimental opt-in for compatible formats that can carry SH4.
• Updated format policies so standard exports remain capped at SH3 unless SH4 is explicitly preserved.
• Improved --info output to report SPZ versions, legacy vs standard SPZ files, and SH4 as an extended non-standard schema where applicable.
• Updated the format matrix and documentation to reflect native SPZ v4 support and the experimental SH4 preservation policy.

Release 0.8.2 - Changelog

• Avoid importing gsconverter from setup.py before dependencies are installed.

Release 0.8.1 - Changelog

• Merge PR #30: replace plyfile with built-in PLY reader/writer
• @swell-d introduced a built-in PLY reader/writer to replace the GPL-licensed plyfile dependency, making the project truly MIT-compliant as requested in #29.
• Added a minimal internal PLY implementation covering the exact API surface used by gsconverter.
• Fixed PLY import handling so --info and other PLY paths work reliably with the built-in reader.
• Improved canonical 3DGS roundtrips so cc -> 3dgs no longer carries RGB and the output stays aligned with the original 3DGS format.
• Preserved extra PLY elements when explicitly requested, so supported metadata can survive conversion paths.
• Thanks to @swell-d for the PR and for solving the licensing issue in a clean way.

Release 0.8 - Changelog

• Significant Core Refactoring: Completely re-architected codebase into modular format handlers and processing pipelines
• Universal Format Support: Implemented robust N-to-N conversion for 3DGS, KSplat, SPZ, SOG, Splat, CloudCompare, and Parquet
• GPU-Accelerated Backend: Integrated Taichi Lang for high-performance parallel processing operations
• Advanced SOR Filtering: Added Statistical Outlier Removal filter with configurable k-neighbors and sigma parameters
