May 2026 (tanstack/router) - Reliability and production-readiness improvements. Focused on ensuring runtime dependencies are correctly configured to prevent production-time failures. Implemented Production Dependency Assurance by moving fetchdts from devDependencies to dependencies, ensuring it is included in production builds. No new user-facing features were delivered this month; the work centers on stability, correctness, and deployment reliability.

January 2025 monthly summary for open-telemetry/opentelemetry-js-contrib. Delivered a targeted bug fix to the Fastify instrumentation plugin, restoring the missing errorCodes export and ensuring compatibility with newer Fastify versions. Implemented automated tests to verify error codes exposure and prevent regressions. The changes improve reliability for Fastify-integrated apps relying on OpenTelemetry error codes, reducing upgrade risk and improving observability.
