Package Type Update Change
google.golang.org/grpc require minor v1.75.1 → v1.82.1

Release Notes

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

v1.82.1: Release 1.82.1

Compare Source

Security

  • server: Stop reading from the connection when flooded by HTTP/2 frames. The default value for this limit is 100 frames, excluding DATA and HEADERS, and may be changed by setting environment variable GRPC_GO_EXPERIMENTAL_CONTROL_BUFFER_THROTTLE_LIMIT.
  • xds/rbac: Support Metadata and RequestedServerName permissions matcher fields. If present in a DENY rule, previously these would be ignored and fail-open.
  • xds/rbac: Fix panic when parsing unsupported fields in NotRule/NotId permissions.
  • xds/rbac: Support the deprecated source_ip principal identifier by treating it as equivalent to direct_remote_ip.

v1.82.0: Release 1.82.0

Compare Source

Behavior Changes

  • server: Remove support for GRPC_GO_EXPERIMENTAL_DISABLE_STRICT_PATH_CHECKING environment varibale. Strict incoming RPC path validation (which has been the default since v1.79.3) can no longer be disabled. (#​9112)
  • transport: Add environment variable to change the default max header list size from 16MB to 8KB. This may be enabled by setting GRPC_GO_EXPERIMENTAL_ENABLE_8KB_DEFAULT_HEADER_LIST_SIZE=true. This will be enabled by default in a subsequent release. (#​9019)
  • balancer: Load Balancing policy registry is now case-sensitive. Set GRPC_GO_EXPERIMENTAL_CASE_SENSITIVE_BALANCER_REGISTRIES=false (and file an issue) to revert to case-insensitive behavior. (#​9017)

New Features

  • experimental/stats: Expose a new API, NewContextWithLabelCallback, to register a callback that is invoked when telemetry labels are added. (#​8877)
  • client: Return a portion of the response body in the error message, when the client receives an unexpected non-gRPC HTTP response, to make debugging easier. (#​8929)
  • server: Add environment variable GRPC_GO_SERVER_GOROUTINE_LABELS that controls setting runtime/pprof.Labels on goroutines spawned by the server. Set GRPC_GO_SERVER_GOROUTINE_LABELS=grpc.method=true to add the grpc.method label on goroutines spawned to handle incoming requests. (#​9082)

Bug Fixes

  • xds/server: Fix a memory leak of HTTP filter instances occurring when route configurations are updated in-place during a Route Discovery Service (RDS) update. (#​9138)
  • grpc: In the deprecated gzip Compressor (used via the deprecated WithCompressor dial option), enforce the MaxRecvMsgSize limit on the decompressed message buffer, preventing excessive memory allocation from highly compressed payloads. (#​9114)
  • stats/opentelemetry: Record retry attempts, grpc.previous-rpc-attempts, at the call level and not the attempt level. (#​8923)
  • encoding: Ensure Close() is always called on readers returned from Compressor.Decompress if possible. (#​9135)
  • channelz: Fix the LastMessageSentTimestamp and LastMessageReceivedTimestamp fields in SocketMetrics to ensure they contain correct timestamp values. (#​9109)

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)

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)
  • xds: fix incorrect proto field access in the weighted round robin (WRR) configuration where blackout_period was used instead of weight_expiration_period. (#​8915)
  • 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)
  • 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)

Bug Fixes

  • credentials/tls: Fix a bug where the port was not stripped from the authority override before validation. (#​8726)
  • 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)
  • transport: Fix an issue where the HTTP/2 server could skip header size checks when terminating a stream early. (#​8769)
  • server: Propagate status detail headers, if available, when terminating a stream during request header processing. (#​8754)

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)

v1.78.0: Release 1.78.0

Compare Source

Behavior Changes

  • client: Align URL validation with Go 1.26+ to now reject target URLs with unbracketed colons in the hostname. (#​8716)
  • transport/client : Return status code Unknown on malformed grpc-status. (#​8735)
    • xds/resolver:
    • Drop previous route resources and report an error when no matching virtual host is found.
    • Only log LDS/RDS configuration errors following a successful update and retain the last valid resource to prevent transient failures. (#​8711)

New Features

  • stats/otel: Add backend service label to weighted round robin metrics as part of A89. (#​8737)
  • stats/otel: Add subchannel metrics (without the disconnection reason) to eventually replace the pickfirst metrics. (#​8738)
  • client: Wait for all pending goroutines to complete when closing a graceful switch balancer. (#​8746)
  • client: Add experimental.AcceptCompressors so callers can restrict the grpc-accept-encoding header advertised for a call. (#​8718)

Bug Fixes

  • xds: Fix a bug in StringMatcher where regexes would match incorrectly when ignore_case is set to true. (#​8723)
  • client:
    • Change connectivity state to CONNECTING when creating the name resolver (as part of exiting IDLE).
    • Change connectivity state to TRANSIENT_FAILURE if name resolver creation fails (as part of exiting IDLE).
    • Change connectivity state to IDLE after idle timeout expires even when current state is TRANSIENT_FAILURE.
    • Fix a bug that resulted in OnFinish call option not being invoked for RPCs where stream creation failed. (#​8710)
  • xdsclient: Fix a race in the xdsClient that could lead to resource-not-found errors. (#​8627)

Performance Improvements

  • mem: Round up to nearest 4KiB for pool allocations larger than 1MiB. (#​8705)

v1.77.0: Release 1.77.0

Compare Source

API Changes

  • mem: Replace the Reader interface with a struct for better performance and maintainability. (#​8669)

Behavior Changes

  • balancer/pickfirst: Remove support for the old pick_first LB policy via the environment variable GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST=false. The new pick_first has been the default since v1.71.0. (#​8672)

Bug Fixes

  • xdsclient: Fix a race condition in the ADS stream implementation that could result in resource-not-found errors, causing the gRPC client channel to move to TransientFailure. (#​8605)
  • client: Ignore HTTP status header for gRPC streams. (#​8548)
  • client: Set a read deadline when closing a transport to prevent it from blocking indefinitely on a broken connection. (#​8534)
  • client: Fix a bug where default port 443 was not automatically added to addresses without a specified port when sent to a proxy.
    • Setting environment variable GRPC_EXPERIMENTAL_ENABLE_DEFAULT_PORT_FOR_PROXY_TARGET=false disables this change; please file a bug if any problems are encountered as we will remove this option soon. (#​8613)
  • balancer/pickfirst: Fix a bug where duplicate addresses were not being ignored as intended. (#​8611)
  • server: Fix a bug that caused overcounting of channelz metrics for successful and failed streams. (#​8573)
  • balancer/pickfirst: When configured, shuffle addresses in resolver updates that lack endpoints. Since gRPC automatically adds endpoints to resolver updates, this bug only affects custom LB policies that delegate to pick_first but don't set endpoints. (#​8610)
  • mem: Clear large buffers before re-using. (#​8670)

Performance Improvements

New Features

  • outlierdetection: Add metrics specified in gRFC A91. (#​8644)
  • stats/opentelemetry: Add support for optional label grpc.lb.backend_service in per-call metrics (#​8637)
  • xds: Add support for JWT Call Credentials as specified in gRFC A97. Set environment variable GRPC_EXPERIMENTAL_XDS_BOOTSTRAP_CALL_CREDS=true to enable this feature. (#​8536)

Dependencies

Bug Fixes

  • client: Return status INTERNAL when a server sends zero response messages for a unary or client-streaming RPC. (#​8523)
  • client: Fail RPCs with status INTERNAL instead of UNKNOWN upon receiving http headers with status 1xx and END_STREAM flag set. (#​8518)
  • pick_first: Fix race condition that could cause pick_first to get stuck in IDLE state on backend address change. (#​8615)

New Features

  • credentials: Add credentials/jwt package providing file-based JWT PerRPCCredentials (A97). (#​8431)

Performance Improvements

  • client: Improve HTTP/2 header size estimate to reduce re-allocations. (#​8547)
  • encoding/proto: Avoid redundant message size calculation when marshaling. (#​8569)

Use the [WithSharedWriteBuffer](https://pkg.go.dev/google.golang.org/grpc#WithSharedWriteBuffer) dial option or the [SharedWriteBuffer](https://pkg.go.dev/google.golang.org/grpc#SharedWriteBuffer) server option to disable this feature. ([#&#8203;8957](https://github.com/grpc/grpc-go/issues/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. ([#&#8203;8997](https://github.com/grpc/grpc-go/issues/8997)) - mem: add a faster tiered buffer pool; use the experimental [mem.NewBinaryTieredBufferPool](https://pkg.go.dev/google.golang.org/grpc/mem@master#NewBinaryTieredBufferPool) function to create such pools.
