April 2026 monthly summary for ag-ui protocol: Implemented robust Server-Sent Events (SSE) streaming in the middleware using FastAPI EventSourceResponse, improving reliability of long-lived agent streams with 15s keep-alive pings and appropriate Cache-Control/X-Accel-Buffering headers. To maintain downstream compatibility, the SSE backend was switched to sse-starlette, restoring the runtime floor to >=0.115.2 while preserving wire-format. Introduced Accept-header based content negotiation to selectively serve SSE (text/event-stream) versus legacy streaming, ensuring binary encoders remain functional when negotiating content type. Expanded test coverage (775 tests passed, 4 skipped) and added tests for dependency behavior (simulating older FastAPI versions) and the Accept-branch. Updated configuration and docs to reflect dependency changes (pyproject.toml) and CHANGELOG updates.

March 2026 performance highlights a major reliability and data-handling improvement across the UI toolchain, focusing on robust serialization of tool-call arguments and stabilization of middleware serialization paths. Delivered a generic JSON serialization utility and streamlined usage across core components, with targeted fixes to prevent runtime errors in production.

January 2026 monthly summary for IBM/mcp-context-forge: Delivered FastMCP compatibility and Dynamic Client Registration (DCR) enhancements, introduced issuer normalization migration, and strengthened refresh token handling. Added a configurable option to request refresh tokens even when the Authorization Server does not advertise support, and expanded test coverage to ensure robustness. Focused on interoperability, stability, and reducing duplicate registrations to improve operational reliability and client onboarding.
