I am pleased to announce the release of AmunPy 1.0.0, the first stable version of the Python interface for reading and analyzing AMUN Code simulation snapshots.

This release represents a complete rewrite and modernization of the package, providing a clean, tested, and well-defined API for both 2D and 3D data.

Highlights of version 1.0.0

• Fully redesigned AmunXML and AmunH5 readers with strict snapshot integrity verification
• Robust support for multiple compression formats (none, lz4, zstd, lzma)
• Unified and tested binary decoding pipeline (compression and byte-level encodings)
• Consistent handling of adaptive mesh refinement (AMR) metadata
• Cross-format validation ensuring identical results between XML and HDF5 snapshots
• Comprehensive automated test suite (all tests passing)
• Modern Python packaging based on pyproject.toml (PEP 517/621)

AmunPy 1.0.0 is intended as a stable foundation for future extensions, including derived fields, advanced analysis tools, and visualization workflows.
