xds/rbac: Support the deprecated source_ip principal identifier by treating it as equivalent to direct_remote_ip .
server: Stop reading from the connection when flooded by HTTP/2 frames. The default value for this limit is 100 frames, excluding DATA and HEADERS, and may be changed by setting environment variable GRPC_GO_EXPERIMENTAL_CONTROL_BUFFER_THROTTLE_LIMIT .
xds/rbac: Support Metadata and RequestedServerName permissions matcher fields. If present in a DENY rule, previously these would be ignored and fail-open.
xds/rbac: Fix panic when parsing unsupported fields in NotRule / NotId permissions.

server: Remove support for GRPC_GO_EXPERIMENTAL_DISABLE_STRICT_PATH_CHECKING environment varibale. Strict incoming RPC path validation (which has been the default since v1.79.3 ) can no longer be disabled. ( #9112 )
transport: Add environment variable to change the default max header list size from 16MB to 8KB . This may be enabled by setting GRPC_GO_EXPERIMENTAL_ENABLE_8KB_DEFAULT_HEADER_LIST_SIZE=true . This will be enabled by default in a subsequent release. ( #9019 )
balancer: Load Balancing policy registry is now case-sensitive. Set GRPC_GO_EXPERIMENTAL_CASE_SENSITIVE_BALANCER_REGISTRIES=false (and file an issue) to revert to case-insensitive behavior. ( #9017 )
experimental/stats: Expose a new API, NewContextWithLabelCallback , to register a callback that is invoked when telemetry labels are added. ( #8877 )
Special Thanks: @seth-epps
client: Return a portion of the response body in the error message, when the client receives an unexpected non-gRPC HTTP response, to make debugging easier. ( #8929 )
Special Thanks: @chengxilo
server: Add environment variable GRPC_GO_SERVER_GOROUTINE_LABELS that controls setting runtime/pprof.Labels on goroutines spawned by the server. Set GRPC_GO_SERVER_GOROUTINE_LABELS=grpc.method=true to add the grpc.method label on goroutines spawned to handle incoming requests. ( #9082 )
Special Thanks: @dfinkel
xds/server: Fix a memory leak of HTTP filter instances occurring when route configurations are updated in-place during a Route Discovery Service (RDS) update. ( #9138 )
grpc: In the deprecated gzip Compressor (used via the deprecated WithCompressor dial option), enforce the MaxRecvMsgSize limit on the decompressed message buffer, preventing excessive memory allocation from highly compressed payloads. ( #9114 )
Special Thanks: @evilgensec
stats/opentelemetry: Record retry attempts, grpc.previous-rpc-attempts , at the call level and not the attempt level. ( #8923 )
encoding: Ensure Close() is always called on readers returned from Compressor.Decompress if possible. ( #9135 )
channelz: Fix the LastMessageSentTimestamp and LastMessageReceivedTimestamp fields in SocketMetrics to ensure they contain correct timestamp values. ( #9109 )
