v0.40.0

Release date: 2026-09-30

Changed

• Upgrade MCP to 1.28.1, development HTTPX2/httpcore2 to 2.12.0, and Vitest/coverage to 4.1.11; refresh locked dependencies, including AnyIO 4.15.1, cryptography 50.0.2, and PyJWT 2.15.1, to address known dependency advisories (10cbecc8).

Fixed

• Restore MCP HTTP connections with custom headers using the supported SDK client API. Isolate connection lifetimes so disconnects, timeouts, and cleanup do not disrupt other servers or hang shutdown (10cbecc8).

Internal

• Expand MCP regression coverage with real-SDK HTTP and stdio tests for authentication, multi-server isolation, failures, timeouts, cleanup, and process exit; update frontend test mocks for Vitest 4 (10cbecc8).
