Release Notes

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

v1.81.1: Release 1.81.1

Compare Source

Security

  • xds/rbac: Fix a potential authorization bypass caused by incorrectly falling through URI/DNS SANs to Subject Distinguished Name (DN) when matching the authenticated principal name. With this fix, only the first non-empty identity source will be used, as per gRFC A41. (#​9111)

Bug Fixes

  • otel: Segregate client and server RPC information used for metrics and traces, to avoid one overwriting the other. (#​9081)

v1.81.0: Release 1.81.0

Compare Source

Behavior Changes

  • balancer/rls: Switch gauge metrics to asynchronous emission (once per collection cycle) to reduce telemetry noise and align with other gRPC language implementations. (#​8808)

Dependencies

  • Minimum supported Go version is now 1.25. (#​8969)

Bug Fixes

  • xds: Use the leaf cluster's security config for the TLS handshake instead of the aggregate cluster's config. (#​8956)
  • transport: Send a RST_STREAM when receiving an END_STREAM when the stream is not already half-closed. (#​8832)
  • xds: Fix ADS resource name validation to prevent a panic. (#​8970)

New Features

  • grpc/stats: Add support for custom labels in per-call metrics (gRFC A108). (#​9008)
  • xds: Add support for Server Name Indication (SNI) and SAN validation (gRFC A101). Disabled by default. To enable, set GRPC_EXPERIMENTAL_XDS_SNI=true environment variable. (#​9016)
  • xds: Add support to control which fields get propagated from ORCA backend metric reports to LRS load reports (gRFC A85). Disabled by default. To enable, set GRPC_EXPERIMENTAL_XDS_ORCA_LRS_PROPAGATION=true. (#​9005)
  • xds: Add metrics to track xDS client connectivity and cached resource state (gRFC A78). (#​8807)
  • stats/otel: Enhance grpc.subchannel.disconnections metric by adding disconnection reason to the grpc.disconnect_error label (gRFC A94). This provides granular insights into why subchannels are closing. (#​8973)
  • mem: Add mem.Buffer.Slice() API to slice the buffer like a slice. (#​8977)

Performance Improvements

  • alts: Pool read buffers to lower memory utilization when sockets are unreadable. (#​8964)
  • transport: Pool HTTP/2 framer read buffers to reduce idle memory consumption. Currently limited to Linux for ALTS and non-encrypted transports (TCP, Unix). To disable, set GRPC_GO_EXPERIMENTAL_HTTP_FRAMER_READ_BUFFER_POOLING=false and report any issues. (#​9032)
