Behavior Changes

client: Reject target URLs containing unbracketed colons in the hostname in Go version 1.26+. (#8716)
- Special Thanks: @neild

New Features

stats/otel: Add backend service label to wrr 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)
- Special Thanks: @twz123

Bug Fixes

transport/client : Return status code Unknown on malformed grpc-status. (#8735)
client: Add experimental.AcceptCompressors so callers can restrict the grpc-accept-encoding header advertised for a call. (#8718)
- Special Thanks: @iblancasa
xds: Fix a bug in StringMatcher where regexes would match incorrectly when ignore_case is set to true. (#8723)
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)
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)
- Special Thanks: @cjc25

`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)
- Special Thanks: @jgold2-stripe
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)
- Special Thanks: @hugehoo
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

transport: Reduce heap allocations to reduce time spent in garbage collection. (#8624, #8630, #8639, #8668)

`v1.76.0`: Release 1.76.0

Compare Source

Dependencies

Minimum supported Go version is now 1.24 (#8509)
- Special Thanks: @kevinGC

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)
- Special Thanks: @vinothkumarr227
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)
- Special Thanks: @dimpavloff

Performance Improvements

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

`v1.75.1`: Release 1.75.1

Compare Source

Bug Fixes

transport: Fix a data race while copying headers for stats handlers in the std lib http2 server transport. (#8519)
xdsclient:
- Fix a data race caused while reporting load to LRS. (#8483)
- Fix regression preventing empty node IDs when creating an LRS client. (#8483)
server: Fix a regression preventing streams from being cancelled or timed out when blocked on flow control. (#8528)

`v1.75.0`: Release 1.75.0

Compare Source

Behavior Changes

xds: Remove support for GRPC_EXPERIMENTAL_XDS_FALLBACK environment variable. Fallback support can no longer be disabled. (#8482)
stats: Introduce DelayedPickComplete event, a type alias of PickerUpdated. (#8465)
- This (combined) event will now be emitted only once per call, when a transport is successfully selected for the attempt.
- OpenTelemetry metrics will no longer have multiple "Delayed LB pick complete" events in Go, matching other gRPC languages.
- A future release will delete the PickerUpdated symbol.
credentials: Properly apply grpc.WithAuthority as the highest-priority option for setting authority, above the setting in the credentials themselves. (#8488)
- Now that this WithAuthority is available, the credentials should not be used to override the authority.
round_robin: Randomize the order in which addresses are connected to in order to spread out initial RPC load between clients. (#8438)
server: Return status code INTERNAL when a client sends more than one request in unary and server streaming RPC. (#8385)
- This is a behavior change but also a bug fix to bring gRPC-Go in line with the gRPC spec.

New Features

dns: Add an environment variable (GRPC_ENABLE_TXT_SERVICE_CONFIG) to provide a way to disable TXT lookups in the DNS resolver (by setting it to false). By default, TXT lookups are enabled, as they were previously. (#8377)

Bug Fixes

xds: Fix regression preventing empty node IDs in xDS bootstrap configuration. (#8476)
- Special Thanks: @davinci26
xds: Fix possible panic when certain invalid resources are encountered. (#8412)
- Special Thanks: @wooffie

xds: Fix possible panic when clusters are removed from the xds configuration. (#8428)
xdsclient: Fix a race causing "resource doesn not exist" when rapidly subscribing and unsubscribing to the same resource. (#8369)
client: When determining the authority, properly percent-encode (if needed, which is unlikely) when the target string omits the hostname and only specifies a port (grpc.NewClient(":<port-number-or-name>")). (#8488)

Bug Fixes

xds: Fix a regression preventing empty node IDs in the bootstrap configuration. (#8476 , #8483)
xdsclient: Fix a data race caused while reporting load to LRS. (#8483)
server: Fix a regression preventing streams from being cancelled or timed out when blocked on flow control. (#8528)

`v1.74.2`: Release 1.74.2

Compare Source

New Features

grpc: introduce new DialOptions and ServerOptions (WithStaticStreamWindowSize, WithStaticConnWindowSize, StaticStreamWindowSize, StaticConnWindowSize) that force fixed window sizes for all HTTP/2 connections. By default, gRPC uses dynamic sizing of these windows based upon a BDP estimation algorithm. The existing options (WithInitialWindowSize, etc) also disable BDP estimation, but this behavior will be changed in a following release. (#8283)

API Changes

balancer: add ExitIdle method to Balancer interface. Earlier, implementing this method was optional. (#8367)

Behavior Changes

xds: Remove the GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST environment variable that allows disabling the least request balancer with xDS. Least request was made available by default with xDS in v1.72.0. (#8248)
- Special Thanks: @atollena
server: allow 0s grpc-timeout header values, which older gRPC-Java versions could send. This restores the behavior of grpc-go before v1.73.0. (#8439)

Bug Fixes

googledirectpath: avoid logging the error message Attempt to set a bootstrap configuration... when creating multiple directpath channels. (#8419)

Performance Improvements

transport: reduce heap allocations by pooling objects and avoiding method-to-closure conversions. (#8361)
transport: reduce heap allocations by re-using mem.Reader objects. (#8360)

Documentation

examples: add examples to demonstrate enabling experimental metrics using the OpenTelemetry plugin. (#8388)
- Special Thanks: @vinothkumarr227

`v1.71.0`: Release 1.71.0

Compare Source

API Changes

balancer: Custom LB policies that record metrics must use the new MetricsRecorder method on Balancer.ClientConn instead of the removed Balancer.BuildOptions.MetricsRecorder field to obtain a metrics recorder. (#8027)
balancer: balancer.ClientConn implementations must now embed a delegate implementation. This allows grpc-go to add new methods to the interface and remain backward compatible. (#8026)
balancer/endpointsharding: The constructor accepts the child balancer's builder and a struct with optional configuration. (#8052)

New Features

xds: Add support for dualstack via the additional_addresses field in the Endpoint resource. To disable this feature, set the environment variable GRPC_EXPERIMENTAL_XDS_DUALSTACK_ENDPOINTS=false. (#8134)
stats/opentelemetry: Add experimental support for OpenTelemetry tracing. (#7852)

examples/features/dualstack: New example demonstrating usage of endpoints and dualstack functionality. (#8098)

`v1.70.0`: Release 1.70.0

Compare Source

Behavior Changes

client: reject service configs containing an invalid retryPolicy in accordance with gRFCs A21 and A6. (#7905)
- Note that this is a potential breaking change for some users using an invalid configuration, but continuing to allow this behavior would violate our cross-language compatibility requirements.

New Features

xdsclient: fallback to a secondary management server (if specified in the bootstrap configuration) when the primary is down is enabled by default. Can be disabled by setting the environment variable GRPC_EXPERIMENTAL_XDS_FALLBACK to false. (#7949)
experimental/credentials: experimental transport credentials are added which don't enforce ALPN. (#7980)
- These credentials will be removed in an upcoming grpc-go release. Users must not rely on these credentials directly. Instead, they should either vendor a specific version of gRPC or copy the relevant credentials into their own codebase if absolutely necessary.

Bug Fixes

xds: fix a possible deadlock that happens when both the client application and the xDS management server (responsible for configuring the client) are using the xds:/// scheme in their target URIs. (#8011)

Performance

server: for unary requests, free raw request message data as soon as parsing is finished instead of waiting until the method handler returns. (#7998)
- Special Thanks: @lqs

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)

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)
