What's New in the Qt GRPC library in 6.11

Qt 6.11 delivers notable improvements to the Qt GRPC library across stability, safety, and performance. Internal testing infrastructure was significantly expanded, uncovering and fixing numerous subtle issues, many of which were backported to Qt 6.8. On the transport side, QGrpcHttp2Channel now supports reading compressed messages. New API additions include a serverInitialMetadataReceived signal for early metadata handling and metadata filtering options on both QGrpcChannelOptions and QGrpcCallOptions. The headline feature is client-side interceptors via QGrpcInterceptorChain, enabling cross-cutting concerns like logging, authentication, and metrics to be applied consistently across RPCs without modifying call sites. A LoggingInterceptor example demonstrates full RPC lifecycle visibility in the Qt GRPC Chat application.
