FixedMathSharp v3.0.1

Fixed

• Fixed a Fixed64 initialization issue that could trigger circular static-constructor errors when operators were used during type initialization.
• Updated internal max/min fallback paths to avoid relying on static members during early initialization.

Added

• Added a NoMemoryPack build/package variant for consumers that want to use FixedMathSharp without the MemoryPack dependency.
• Added a compile-time shim so the library can build cleanly when MemoryPack is disabled.

Changed

• Updated build and packaging scripts to produce both standard and NoMemoryPack release outputs.
• Migrated the solution to .slnx and refreshed CI/workflow configuration accordingly.
• Improved public documentation and README guidance, including package selection and Unity/Burst recommendations.
