[1.0.2] - 2025-10-30

Changed

• Refactored directory variable naming from NFX_DATATYPES_ROOT_DIR to NFX_DATATYPES_DIR for consistency

• GitHub Actions Release Workflow

  • Removed automatic trigger on release publication to prevent GitHub Pages protection errors

[1.0.1] - 2025-10-28

Changed

• GitHub Actions Release Workflow

  • Added mandatory tag validation to prevent accidental releases
  • Added semantic versioning format verification (X.Y.Z)
  • Added create-release job to create GitHub release first
  • Added job dependencies (needs: create-release) for proper release workflow ordering
  • Set all release uploads to draft: true for manual review before publishing
  • Removed problematic github.ref_name fallback that could create “main” releases
  • Changed fail_on_unmatched_files to false for better error handling
  • Added GCC-14 installation via PPA for Ubuntu 22.04 compatibility
  • Added package verification steps for all build jobs (Linux, Windows, Source)
  • Added SHA256 checksum generation for all packages
  • Added workflow artifacts upload with 7-day retention for debugging
  • Removed redundant CMake compiler flags (MSVC environment auto-detection)

• Documentation Configuration

  • Fixed Doxygen paths to use NFX_DATATYPES_ROOT_DIR instead of CMAKE_SOURCE_DIR for better modularity
  • Updated paths in doc/CMakeLists.txt for README, CHANGELOG, and sample files

Added

• Release Workflow Enhancements
  • Package verification with detailed logging and error reporting
  • SHA256SUMS.txt files for all Linux and Windows packages
  • SHA256SUMS-source.txt for source packages
  • Workflow artifacts for post-build debugging and verification
  • Build validation before release upload

[1.0.0] - 2025-10-26 - Initial Release

Added

• Int128: Cross-platform 128-bit signed integer arithmetic

  • Native __int128 support on GCC/Clang for maximum performance
  • Hand-optimized implementation for MSVC using 64-bit operations
  • Full range: -2^127 to 2^127-1
  • Complete arithmetic operators (+, -, *, /, %, unary -)
  • Comparison operators (==, !=, <, <=, >, >=)
  • Type conversions (int32, int64, uint64, float, double, Decimal)
  • String parsing and formatting (parse(), tryParse(), toString())
  • State checking methods (isZero(), isNegative())
  • Bit manipulation (toLow(), toHigh(), toBits())

• Decimal: High-precision decimal arithmetic

  • 96-bit mantissa with 8-bit scale (0-28 decimal places)
  • Up to 28-29 significant digits
  • Exact decimal representation (no binary floating-point errors)
  • Complete arithmetic operators (+, -, *, /, unary -)
  • Comparison operators (==, !=, <, <=, >, >=)
  • Type conversions (int32, int64, uint64, float, double, Int128)
  • String parsing and formatting (parse(), tryParse(), toString())
  • Mathematical operations (abs(), truncate(), floor(), ceiling(), round())
  • State checking methods (isZero(), isNegative(), scale(), decimalPlacesCount())
  • Cross-type arithmetic (Decimal ↔ Int128 interoperability)

• Build System

  • CMake 3.20+ configuration with modular structure
  • Static and shared library targets
  • Cross-platform support (Linux GCC/Clang, Windows MinGW/Clang/MSVC)
  • Google Test integration for unit testing
  • Google Benchmark integration for performance benchmarking
  • Doxygen documentation generation support
  • CPack packaging for distribution (DEB, RPM, ZIP, WIX)
  • Installation support with CMake package config
