Release Notes

grpc/grpc-go (google.golang.org/grpc)

v1.68.0: Release 1.68.0

Compare Source

Behavior Changes

• stats/opentelemetry/csm: Get mesh_id local label from "CSM_MESH_ID" environment variable, rather than parsing from bootstrap file (#​7740)
• orca (experimental): if using an ORCA listener, it must now be registered only on a READY SubConn, and the listener will automatically be stopped when the connection is lost. (#​7663)
• client: ClientConn.Close() now closes transports simultaneously and waits for transports to be closed before returning. (#​7666)
• credentials: TLS credentials created via NewTLS that use tls.Config.GetConfigForClient will now have CipherSuites, supported TLS versions and ALPN configured automatically. These were previously only set for configs not using the GetConfigForClient option. (#​7709)

Bug Fixes

• transport: prevent deadlock in client transport shutdown when writing the GOAWAY frame hangs. (#​7662)
• mem: reuse buffers more accurately by using slice capacity instead of length (#​7702)
  • Special Thanks: @​PapaCharlie
• status: Fix regression caused by #​6919 in status.Details() causing it to return a wrapped type when getting proto messages generated with protoc-gen-go < v1.
  • Special Thanks: @​Clement-Jean

Dependencies

• Bump minimum supported Go version to go1.22.7. (#​7624)

v1.67.1: Release 1.67.1

Compare Source

Bug Fixes

• transport: Fix a bug causing stream failures due to miscalculation of the flow control window in both clients and servers. (#​7667)
• xds/server: Fix xDS Server memory leak. (#​7681)

v1.67.0: Release 1.67.0

Compare Source

Bug Fixes

• ringhash: when used with multiple EDS priorities, fix bug that could prevent a higher priority from recovering from transient failure. (#​7364)
  • Special Thanks: @​atollena

Behavior Changes

• In accordance with RFC 7540, clients and servers will now reject TLS connections that don't support ALPN. This can be disabled by setting the environment variable GRPC_ENFORCE_ALPN_ENABLED to false (case insensitive). Please file a bug if you encounter any issues with this behavior. The environment variable to revert this behavior will be removed in an upcoming release. (#​7535)

v1.66.3: Release 1.66.3

Bug Fixes

v1.66.1

Compare Source

v1.66.0: Release 1.66.0

Compare Source

New Features

• metadata: stabilize ValueFromIncomingContext (#​7368)
  • Special Thanks: @​KarthikReddyPuli
• client: stabilize the WaitForStateChange and GetState methods, which were previously experimental. (#​7425)
• xds: Implement ADS flow control mechanism (#​7458)
  • See https://github.com/grpc/grpc/issues/34099 for context.
• balancer/rls: Add metrics for data cache and picker internals (#​7484, #​7495)
• xds: LRS load reports now include the total_issued_requests field. (#​7544)

Bug Fixes

• grpc: Clients now return status code INTERNAL instead of UNIMPLEMENTED when the server uses an unsupported compressor. This is consistent with the gRPC compression spec. (#​7461)
  • Special Thanks: @​Gayathri625
• transport: Fix a bug which could result in writes busy looping when the underlying conn.Write returns errors (#​7394)
  • Special Thanks: @​veshij
• client: fix race that could lead to orphaned connections and associated resources. (#​7390)
• xds: use locality from the connected address for load reporting with pick_first (#​7378)
  • without this fix, if a priority contains multiple localities with pick_first, load was reported for the wrong locality
• client: prevent hanging during ClientConn.Close() when the network is unreachable (#​7540)

Performance Improvements

• transport: double buffering is avoided when using an http connect proxy and the target server waits for client to send the first message. (#​7424)
• codec: Implement a new Codec which uses buffer recycling for encoded message (#​7356)
  • introduce a mem package to facilitate buffer reuse (#​7432)
  • Special Thanks: @​PapaCharlie

Behavior Changes

• grpc: Return canonical target string from ClientConn.Target() and resolver.Address.String() (#​6923)

Bug Fixes

• server: wait to close connection until incoming socket is drained (with timeout) to prevent data loss on client-side (#​6977)
  • Special Thanks: @​s-matyukevich for discovering the root cause

Performance Improvements

• *: Allow building without x/net/trace by using grpcnotrace to enable dead code elimination (#​6954)

Dependencies

• *: Use google.golang.org/protobuf/proto instead of github.com/golang/protobuf. (#​6919)
  • Special Thanks: @​Clement-Jean

[!NOTE]
The above change in proto library usage introduces a minor behavior change within those libraries. The old github.com/golang/protobuf library would error if given a nil message to Marshal, while the new google.golang.org/protobuf library will successfully output zero bytes in this case. This means server method handlers that did return nil, nil will now return an empty message and no error, while it used to return an error. This also affects the client side, where clients sending nil messages used to fail without sending the RPC, and now they will send an empty message.
