[0.7.0] - 2026-02-15

Added

• build: NFX_STRINGBUILDER_ENABLE_SIMD option to control SIMD optimizations (ON by default, can be disabled for WASM targets)

Changed

• build: simplified CMake packaging configuration (source packages only, removed DEB/RPM/WIX complexity)
• build: cleaned up CMake structure and removed redundant configuration options

[0.6.2] - 2026-02-14

Changed

• build: extend strict compiler warnings to benchmarks, samples, and tests targets

[0.6.1] - 2026-02-14

Changed

• build: enforce strict compiler warnings (-Wall -Wextra -Werror for GCC/Clang, /W4 /WX for MSVC)

Fixed

• Missing #include <array> in samples/Sample_StringBuilder.cpp

[0.6.0] - 2026-02-11

Added

• Line-based operations: appendLine(str) and appendLn(str) - append string with automatic newline character
• Join operations: join(container, delimiter) - join collection elements with delimiter (supports both string_view and char delimiters)

Changed

• chore(deps): bump google-benchmark from 1.9.4 to 1.9.5

[0.5.0] - 2026-01-27

Added

• Template overloads for string literals with compile-time length deduction (zero strlen() overhead)
• Cross-platform NFX_STRINGBUILDER_FORCE_INLINE macro (MSVC __forceinline, GCC/Clang __attribute__((always_inline)))

Changed

• Numeric append methods write directly to buffer with std::to_chars
• Direct m_buffer pointer access eliminates helper method overhead
• Move-optimized toString() && overload for rvalue instances
• Stack buffer aligned to 32 bytes for better compiler auto-vectorization

[0.4.1] - 2025-12-20

Added

• Prepend operations - StringBuilder::prepend() methods for inserting content at the beginning of the buffer

[0.4.0] - 2025-12-18

Changed

• BREAKING: Simplified architecture - removed pooling system in favor of direct StringBuilder instantiation

Removed

• BREAKING: StringBuilderPool static factory class and three-tier pooling system (thread-local, shared, dynamic)
• BREAKING: StringBuilderLease RAII wrapper for pooled buffer management
• DynamicStringBufferPool internal class

[0.3.0] - 2025-12-07

Added

• Method chaining support for all StringBuilder::append() methods (now return StringBuilder&)
• Numeric append() methods for int8_t, uint8_t, int16_t, uint16_t, int32_t, uint32_t, int64_t, uint64_t, float, and double
• Variadic append() template overload for batch operations - append multiple arguments in a single call (supports strings, chars, and numeric types)

Changed

• Stream operators (operator<<) for all numeric types optimized with std::to_chars implementation
• Optimized capacity checks in DynamicStringBuffer append methods
• SIMD optimizations (AVX2/SSE2) for string copy operations in DynamicStringBuffer::append()
• Growth factor increased from 1.5 to 2.0 for better reallocation performance

[0.2.0] - 2025-12-03

Added

• StringBuilder::reserve() method for consistent API with DynamicStringBuffer

Changed

• Reorganized CMake build configuration for better modularity
• Decentralized dependency management to test/benchmark modules
• Improved package portability with PATH_VARS configuration

[0.1.1] - 2025-11-28

Changed

• Consolidated packaging tool detection in CMake configuration

Fixed

• Removed incorrect runtime dependencies from DEB/RPM packages

[0.1.0] - 2025-11-23 - Initial Release

Added

• Core String Building
  • DynamicStringBuffer with Small Buffer Optimization (256-byte stack buffer)
  • StringBuilder with fluent interface and stream operators (<<)
  • StringBuilderLease RAII wrapper for automatic pool cleanup
  • StringBuilderPool static factory with three-tier pooling strategy
  • std::formatter specializations for DynamicStringBuffer and StringBuilder enabling direct usage in std::format()
  • Numeric type support via operator<< overloads for int32_t, uint32_t, int64_t, uint64_t, float, double
  • Type-safe formatting via format(fmt, args...) method using std::format_to with std::back_inserter
  • Private push_back(char) method as inline alias to append(char) for std::back_inserter compatibility
