v0.1.9

🔧 Maintenance & Quality Release

v0.1.9 focuses on dependency upgrades, protocol compliance, code quality improvements, and documentation enhancements. No breaking changes for end users.

✨ What's New

• MCP Protocol 2025-11-25: MCP Gateway now negotiates using the latest protocol version (2025-11-25), improving compatibility with up-to-date MCP clients and servers (#1619)
• go-sdk v1.4.0: Upgraded the MCP Go SDK to v1.4.0, consolidating protocol constants and removing the deprecated HTTPTransport in favour of the current transport layer (#1598)
• Config Schema v0.53.6: Gateway configuration is validated against the latest spec schema (v0.53.6), picking up all recent schema improvements (#1592, #1610, #1640)
• customSchemas Documentation: New docs clarify how to configure custom schema URLs and the uppercase domain constraint — see the README for details (#1606)

🐛 Bug Fixes & Improvements

• Fixed a duplicate test function (TestWithResponseLogging) that caused lint failures during CI (#1599)
• Corrected the GitHub MCP test session fixture to keep integration tests reliable (#1630)

🔧 Internal

Significant code-health work this cycle: duplicate constants (DefaultLogDir, DefaultPayloadDir, DefaultPayloadSizeThreshold) centralized in the config package, repeated RPCMessageInfo construction eliminated, Docker helpers extracted into a dedicated file, and several micro-files consolidated — making the codebase easier to navigate and maintain (#1567, #1585, #1620, #1641).
