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)
  • Special Thanks: @​al4an444

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)
  • Special Thanks: @​ash2k

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)

v1.80.0: Release 1.80.0

Compare Source

Behavior Changes

• balancer: log a warning if a balancer is registered with uppercase letters, as balancer names should be lowercase. In a future release, balancer names will be treated as case-insensitive; see #​5288 for details. (#​8837)
• xds: update resource error handling and re-resolution logic (#​8907)
  • Re-resolve all LOGICAL_DNS clusters simultaneously when re-resolution is requested.
  • Fail all in-flight RPCs immediately upon receipt of listener or route resource errors, instead of allowing them to complete.

Bug Fixes

• xds: support the LB policy configured in LOGICAL_DNS cluster resources instead of defaulting to pick_first. (#​8733)
• credentials/tls: perform per-RPC authority validation against the leaf certificate instead of the entire peer certificate chain. (#​8831)
• xds: enabling A76 ring hash endpoint keys no longer causes EDS resources with invalid proxy metadata to be NACKed when HTTP CONNECT (gRFC A86) is disabled. (#​8875)
• xds: validate that the sum of endpoint weights in a locality does not exceed the maximum uint32 value. (#​8899)
  • Special Thanks: @​RAVEYUS
• xds: fix incorrect proto field access in the weighted round robin (WRR) configuration where blackout_period was used instead of weight_expiration_period. (#​8915)
  • Special Thanks: @​gregbarasch
• xds/rbac: handle addresses with ports in IP matchers. (#​8990)

New Features

• ringhash: enable gRFC A76 (endpoint hash keys and request hash headers) by default. (#​8922)

Performance Improvements

• credentials/alts: pool write buffers to reduce memory allocations and usage. (#​8919)
• grpc: enable the use of pooled write buffers for buffering HTTP/2 frame writes by default. This reduces memory usage when connections are idle. Use the WithSharedWriteBuffer dial option or the SharedWriteBuffer server option to disable this feature. (#​8957)
• xds/priority: stop caching child LB policies removed from the configuration. This will help reduce memory and cpu usage when localities are constantly switching between priorities. (#​8997)
• mem: add a faster tiered buffer pool; use the experimental mem.NewBinaryTieredBufferPool function to create such pools. (#​8775)

v1.79.3: Release 1.79.3

Compare Source

Security

• server: fix an authorization bypass where malformed :path headers (missing the leading slash) could bypass path-based restricted "deny" rules in interceptors like grpc/authz. Any request with a non-canonical path is now immediately rejected with an Unimplemented error. (#​8981)

v1.79.2: Release 1.79.2

Compare Source

Bug Fixes

• stats: Prevent redundant error logging in health/ORCA producers by skipping stats/tracing processing when no stats handler is configured. (#​8874)

v1.79.1: Release 1.79.1

Compare Source

Bug Fixes

• grpc: Remove the -dev suffix from the User-Agent header. (#​8902)

v1.79.0: Release 1.79.0

Compare Source

API Changes

• mem: Add experimental API SetDefaultBufferPool to change the default buffer pool. (#​8806)
  • Special Thanks: @​vanja-p
• experimental/stats: Update MetricsRecorder to require embedding the new UnimplementedMetricsRecorder (a no-op struct) in all implementations for forward compatibility. (#​8780)

Behavior Changes

• balancer/weightedtarget: Remove handling of Addresses and only handle Endpoints in resolver updates. (#​8841)

New Features

• experimental/stats: Add support for asynchronous gauge metrics through the new AsyncMetricReporter and RegisterAsyncReporter APIs. (#​8780)
• pickfirst: Add support for weighted random shuffling of endpoints, as described in gRFC A113.
  • This is enabled by default, and can be turned off using the environment variable GRPC_EXPERIMENTAL_PF_WEIGHTED_SHUFFLING. (#​8864)
• xds: Implement :authority rewriting, as specified in gRFC A81. (#​8779)
• balancer/randomsubsetting: Implement the random_subsetting LB policy, as specified in gRFC A68. (#​8650)
  • Special Thanks: @​marek-szews

Bug Fixes

• credentials/tls: Fix a bug where the port was not stripped from the authority override before validation. (#​8726)
  • Special Thanks: @​Atul1710
• xds/priority: Fix a bug causing delayed failover to lower-priority clusters when a higher-priority cluster is stuck in CONNECTING state. (#​8813)
• health: Fix a bug where health checks failed for clients using legacy compression options (WithDecompressor or RPCDecompressor). (#​8765)
  • Special Thanks: @​sanki92
• transport: Fix an issue where the HTTP/2 server could skip header size checks when terminating a stream early. (#​8769)
  • Special Thanks: @​joybestourous
• server: Propagate status detail headers, if available, when terminating a stream during request header processing. (#​8754)
  • Special Thanks: @​joybestourous

Performance Improvements

• credentials/alts: Optimize read buffer alignment to reduce copies. (#​8791)
• mem: Optimize pooling and creation of buffer objects. (#​8784)
• transport: Reduce slice re-allocations by reserving slice capacity. (#​8797)
