v2.2.0

Word Case Conversion Engine v2.2.0

The "Memory Sovereignty" Milestone

This release represents the pinnacle of the polyglot architecture, introducing deterministic memory management and significant performance gains.

Core Engineering Improvements:

• Memory Sovereignty: Implemented the Rule of Five and RAII patterns in the C++17 core to eliminate heap friction.
• Zero-Leak Bridge: Hardened the Marshalling Contract between .NET 8 and Native C++ for zero-leak execution under extreme concurrency.
• Throughput Milestone: Benchmarked at 2,827 req/s (a 25% increase over v2.0.0).
• Latency Optimization: Reduced median (P50) latency to 22ms (a 42% improvement).

Technical Changes:

• Self-Contained Deployment: API is now published as a self-contained osx-arm64 binary.
• Binary Optimization: Native .dylib is now stripped of non-essential symbols for production use.
• Stress Validation: Successfully passed a 1,000,000 request endurance soak test with an optimized P99 tail latency.

Installation:

1. Extract WordCaseEngine-v2.2.0-ARM64.zip.
2. Native binaries are pre-linked—no external C++ dependencies required.

v2.1.0

Word Case Conversion Engine v2.0.0 (Generation 2)

The "Millionaire" Milestone & Architecture Hardening

This major release introduces high-availability orchestration and validates the system's industrial-grade endurance.

Major Changes:

• Scale: Integrated NGINX Layer 7 Load Balancing with a 4-replica backend strategy.
• Validation: 1,000,000 request endurance test completed with 100% success rate.
• Performance: Optimized thread-pinning for Apple M2 Performance Cores.
• Observability: Full OpenTelemetry integration for cross-language trace propagation.

Project Maintenance & DX (Developer Experience):

• CI/CD Standardization: Renamed workflows to a domain-specific hierarchy (native-*, dotnet-*, full-stack-*) for better pipeline clarity.
• Doc Migration: Reorganized all technical documentation, performance reports, and design patterns into the /docs directory for a cleaner root structure.
• Security: Re-aligned CodeQL advanced security scanning with the new native engine paths.

Installation:

1. Download WordCaseEngine-ARM64.zip.
2. Follow the setup guide in the /docs folder for local orchestration.
