- Removed the Swift/C++ interop layer and added CONNECT proxy, log level support, and QUIC socket buffer/idle timeout tweaks in Envoy Mobile.
- Extended ext‑proc with retry policies, request/response attributes, dynamic metadata, and URI‑template RBAC; added Fluentd logger, Redis echo command, full‑scan least‑request LB, and upstream Lambda/ext‑proc filter usage.
- Implemented HTTP/2 and QUIC enhancements, JWT header deduplication, server‑preferred address for non‑QUICHE clients, and fixed a load‑balancing initialization bug.
