This major release upgrades the library to module path v2 and introduces significant performance optimizations and new features for high-performance systems.

⚡ What's New

  • Go Modules v2: Updated the module path to github.com/GenshIv/silentjson/v2 to comply with Go semantic versioning standards.
  • Shared Memory (SHM) Integration: Added support for parsing JSON directly from Shared Memory (via mmap) with zero heap allocations. Perfect for ultra-low latency Inter-Process Communication (IPC).
  • Zero-Allocation Marshaling: Introduced MarshalSlice and Marshal functions with buffer reuse support. Now JSON generation is as efficient as parsing.
  • Scalar Parser Optimization: Deep refactoring of the Pure Go (scalar) parser. Performance increased to 829 MB/s, outperforming JIT-based parsers like Sonic even on hardware without AVX2 support.
  • Improved ARM64 Support: Stabilized performance and fallbacks for Apple Silicon and ARM-based servers.
