v1.73.0: Release 1.73.0

Compare Source

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)
  • Special Thanks: @​marcoshuck
• 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)
  • Special Thanks: @​evanj
• xds: fix reported error string when LRS load reporting interval is invalid. (#​8224)
  • Special Thanks: @​alingse

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)
  • Special Thanks: @​evanj

Documentation

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

v1.72.2: Release 1.72.2

Compare Source

Bug Fixes

• client: restore support for NO_PROXY environment variable when connecting to locally-resolved addresses (case 2 from gRFC A1). (#​8329)
• balancer/least_request: fix panic on resolver errors. (#​8333)

v1.72.1: Release 1.72.1

Compare Source

Bug Fixes

• client: HTTP Proxy connections are no longer attempted for addresses with non-TCP network types. (#​8215)
• client: Fix bug that causes RPCs to fail with status INTERNAL instead of CANCELLED or DEADLINE_EXCEEDED when receiving a RST_STREAM frame in the middle of the gRPC message. (#​8289)

v1.72.0: Release 1.72.0

Compare Source

Dependencies

• Minimum supported Go version is now 1.23 (#​8108)

API Changes

• resolver: add experimental AddressMapV2 with generics to ultimately replace AddressMap. Deprecate AddressMap for deletion (#​8187)
• resolver: convert EndpointMap in place to use generics (#​8189)

New Features

• xds: add grpc.xds_client.server_failure counter metric on xDS client to record connectivity errors (#​8203)
• balancer/rls: allow maxAge to exceed 5 minutes if staleAge is set in the LB policy configuration (#​8137)
• ringhash: implement gRFC A76 improvements. (#​8159)
• pickfirst: The new pick first LB policy is made the default. The new LB policy implements the Happy Eyeballs algorithm. To disable the new policy set the environment variable GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST to false (case insensitive).

Bug Fixes

• xds: fix support for circuit breakers and load reporting in LOGICAL_DNS clusters (#​8169, #​8170)
• xds/cds: improve RPC error messages when resources are not found (#​8122)
• balancer/priority: fix race that could leak balancers and goroutines during shutdown (#​8095)
• stats/opentelemetry: fix trace attributes message sequence numbers to start from 0 (#​8237)
• balancer/pickfirstleaf: fix panic if deprecated Address.Metadata field is set to a non-comparable value by ignoring the field (#​8227)

Behavior Changes

• transport: make servers send an HTTP/2 RST_STREAM frame to cancel a stream when the deadline expires (#​8071)

Documentation

• stats: clarify the expected sequence of events on a stats handler (#​7885)
  • Special Thanks: @​RyanBlaney

Bug Fixes

• grpc: fix a bug causing an extra Read from the compressor if a compressed message is the same size as the limit. This could result in a panic with the built-in gzip compressor (#​8178)
• xds: restore the behavior of reading the bootstrap config before creating the first xDS client instead of at package init time (#​8164)
• stats/opentelemetry: use TextMapPropagator and TracerProvider from TraceOptions instead of OpenTelemetry globals (#​8166)
• client: fix races when an http proxy is configured that could lead to deadlocks or panics (#​8195)
• client: fix bug causing RPC failures with message "no children to pick from" when using a custom resolver that calls the deprecated NewAddress API (#​8149)
• wrr: fix slow processing of address updates that could result in problems including RPC failures for servers with a large number of backends (#​8179)
