🌟 Release Highlights

This release focuses on reliability and performance improvements, including accurate health monitoring, faster WASM guard startup, and a self-contained config schema — plus an expanded test suite and numerous internal code quality improvements.

✨ What's New

• Embedded config schema (#2933): The MCP Gateway config JSON schema is now bundled directly into the binary via go:embed, eliminating the dependency on the external schema URL. No internet access needed to validate your configuration.

• Debug logging for HTTP transport (#2906): Added a debug logger to the MCP HTTP transport layer, making it easier to trace request/response flows when troubleshooting backend connectivity issues.

🐛 Bug Fixes & Improvements

• Accurate health endpoint (#2938): The /health endpoint now reports real server status and uptime rather than stale or approximate values — health checks and monitoring tools will reflect the true state of backend MCP servers.

⚡ Performance

• WASM guard startup time reduced (#2956): Added a wazero compilation cache for WASM security guards. Subsequent guard loads reuse compiled artifacts, significantly reducing startup overhead for deployments using WASM-based guards.

📚 Documentation

• Updated CONTRIBUTING.md (#2957): Added missing internal packages (proxy, difc, syncutil) and documented proxy mode to help contributors navigate the codebase.
