Release Notes

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

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)

v1.67.2: Release 1.67.2
