New Features

  • balancer/ringhash: move LB policy from xds/internal to exported path to facilitate use without xds (#​8249)
  • xds: enable least request LB policy by default. It can be disabled by setting GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST=false in your environment. (#​8253)
  • grpc: add a CallAuthority Call Option that can be used to overwrite the http :authority header on per-RPC basis. (#​8068)
  • stats/opentelemetry: add trace event for name resolution delay. (#​8074)
  • health: added List method to gRPC Health service. (#​8155)
  • ringhash: implement features from gRFC A76. (#​8159)
  • xds: add functionality to support SPIFFE Bundle Maps as roots of trust in XDS which can be enabled by setting GRPC_EXPERIMENTAL_XDS_MTLS_SPIFFE=true. (#​8167, #​8180, #​8229, #​8343)

Bug Fixes

  • xds: locality ID metric label is changed to make it consistent with gRFC A78. (#​8256)
  • client: fail RPCs on the client when using extremely short contexts that expire before the grpc-timeout header is created. (#​8312)
  • server: non-positive grpc-timeout header values are now rejected. This is consistent with the gRPC protocol spec. (#​8290)
  • xds: fix reported error string when LRS load reporting interval is invalid. (#​8224)

Performance Improvements

  • credentials/alts: improve read performance by optimizing buffer copies and allocations. (#​8271)
  • server: improve performance of RPC handling by avoid a status proto copy (#​8282)

Documentation

  • examples/features/opentelemetry: modify example to demonstrate tracing using OpenTelemtry plugin. (#​8056)
