summary
gRPC reports growth like 24M weekly Python downloads and rising GitHub stars, and ships concrete features: REST support with a preview at gRPC‑comp in August, OpenTelemetry metrics and tracing across languages, Kubernetes Gateway API gRPCRoute in GA, and a GCP CRD for cookie‑based session affinity. Runtime features include dual‑stack backends with happy‑eyeballs, XDS fallback, proxyless service‑mesh support (XDS host rewriting, JWT auth, SPIFFE mTLS) and XDS global rate limiting via a new RLQS protocol. Proto editions (2023) and a Protoiller CLI are available for migration.
