Sep 1, 2025September 2025 (2025-09) — Helidon repository helidon-io/helidon. Key feature delivered: JsonRpcRequest Context Propagation Enhancement, extending JsonRpcRequest to wrap ServerRequest so the request-scoped context (tracing, security, correlation IDs) is properly propagated through JSON-RPC boundaries. This work involved delegating context-related methods to the underlying ServerRequest to ensure consistent propagation. Commit reference: a6c043bd41b39314d6e38617ee81b1bc6db38572 ("Make request context available in JSON-RPC request (#10712)").
