Release Notes

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

v1.69.2: Release 1.69.2

Compare Source

Bug Fixes

• stats/experimental: add type aliases for symbols (Metrics/etc) that were moved to the stats package (#​7929).
• client: set user-agent string to the correct version.

v1.69.0: Release 1.69.0

Compare Source

Known Issues

• The recently added grpc.NewClient function is incompatible with forward proxies, because it resolves the target hostname on the client instead of passing the hostname to the proxy. A fix is expected to be a part of grpc-go v1.70. (#​7556)

New Features

• stats/opentelemetry: Introduce new APIs to enable OpenTelemetry instrumentation for metrics on servers and clients (#​7874)
• xdsclient: add support to fallback to lower priority servers when higher priority ones are down (#​7701)
• dns: Add support for link local IPv6 addresses (#​7889)
• The new experimental pickfirst LB policy (disabled by default) supports Happy Eyeballs, interleaving IPv4 and IPv6 address as described in RFC-8305 section 4, to attempt connections to multiple backends concurrently. The experimental pickfirst policy can be enabled by setting the environment variable GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST to true. (#​7725, #​7742)
• balancer/pickfirst: Emit metrics from the pick_first load balancing policy (#​7839)
• grpc: export MethodHandler, which is the type of an already-exported field in MethodDesc (#​7796)
  • Special Thanks: @​mohdjishin

Bug Fixes

• credentials/google: set scope for application default credentials (#​7887)
  • Special Thanks: @​halvards
• xds: fix edge-case issues where some clients or servers would not initialize correctly or would not receive errors when resources are invalid or unavailable if another channel or server with the same target was already in use . (#​7851, #​7853)
• examples: fix the debugging example, which was broken by a recent change (#​7833)

Behavior Changes

• client: update retry attempt backoff to apply jitter per updates to gRFC A6. (#​7869)
  • Special Thanks: @​isgj
• balancer/weightedroundrobin: use the pick_first LB policy to manage connections (#​7826)

API Changes

• balancer: An internal method is added to the balancer.SubConn interface to force implementors to embed a delegate implementation. This requirement is present in the interface documentation, but wasn't enforced earlier. (#​7840)

Performance Improvements

• mem: implement a ReadAll() method for more efficient io.Reader consumption (#​7653)
  • Special Thanks: @​ash2k
• mem: use slice capacity instead of length to determine whether to pool buffers or directly allocate them (#​7702)
  • Special Thanks: @​PapaCharlie

Documentation

• examples/csm_observability: Add xDS Credentials and switch server to be xDS enabled (#​7875)

v1.68.2: Release 1.68.2

Compare Source

Dependencies

• Remove the experimental stats/opentelemetry module and instead add the experimental packages it contains directly into the main google.golang.org/grpc module (#​7936)

v1.68.1: Release 1.68.1

Compare Source

Bug Fixes

• credentials/alts: avoid SRV and TXT lookups for handshaker service to work around hangs caused by buggy versions of systemd-resolved. (#​7861)

Dependencies

• Relax minimum Go version requirement from go1.22.7 to go1.22. (#​7831)

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. (#​7724)

Dependencies

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

v1.67.3: Release 1.67.3

Compare Source

Dependencies

• Remove the experimental stats/opentelemetry module and instead add the experimental packages it contains directly into the main google.golang.org/grpc module.

v1.67.2: Release 1.67.2

Compare Source

Bug Fixes

• credentials/alts: avoid SRV and TXT lookups for handshaker service to work around hangs caused by buggy versions of systemd-resolved. (#​7861)

v1.67.1: Release 1.67.1

Compare Source

Bug Fixes

• 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

• transport: Fix a bug causing stream failures due to miscalculation of the flow control window in both clients and servers. (#​7667)

v1.66.1

Compare Source

v1.66.0: Release 1.66.0

Compare Source

New Features

• 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
