Release 1.74.2
New Features
- grpc: introduce new
DialOptionsandServerOptions(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
ExitIdlemethod toBalancerinterface. Earlier, implementing this method was optional. (#8367)
Behavior Changes
- xds: Remove the
GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUESTenvironment 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.Readerobjects. (#8360)
Documentation
- examples: add examples to demonstrate enabling experimental metrics using the OpenTelemetry plugin. (#8388)

Release 1.74.1
Version 1.74.1 retracts release v1.74.0 and itself. Release 1.74.0 was accidentally tagged on the wrong commit and should not be used. Version 1.73.0 should be used until 1.74.2 is released.

Release 1.73.0
New Features
- balancer/ringhash: move LB policy from xds/internal to exported path to facilitate use without xds (#8249)
- xds: enable least request LB policy by default. It can be disabled by setting
GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST=falsein your environment. (#8253) - grpc: add a
CallAuthorityCall Option that can be used to overwrite the http:authorityheader on per-RPC basis. (#8068) - stats/opentelemetry: add trace event for name resolution delay. (#8074)
- health: added
Listmethod to gRPC Health service. (#8155)- Special Thanks: @marcoshuck
- ringhash: implement features from gRFC A76. (#8159)
- xds: add functionality to support SPIFFE Bundle Maps as roots of trust in XDS which can be enabled by setting
GRPC_EXPERIMENTAL_XDS_MTLS_SPIFFE=true. (#8167, #8180, #8229, #8343)
Bug Fixes
- xds: locality ID metric label is changed to make it consistent with gRFC A78. (#8256)
- client: fail RPCs on the client when using extremely short contexts that expire before the
grpc-timeoutheader is created. (#8312) - server: non-positive
grpc-timeoutheader values are now rejected. This is consistent with the gRPC protocol spec. (#8290)- Special Thanks: @evanj
- xds: fix reported error string when LRS load reporting interval is invalid. (#8224)
- Special Thanks: @alingse
Performance Improvements
- credentials/alts: improve read performance by optimizing buffer copies and allocations. (#8271)
- server: improve performance of RPC handling by avoid a status proto copy (#8282)
- Special Thanks: @evanj
Documentation
- examples/features/opentelemetry: modify example to demonstrate tracing using OpenTelemtry plugin. (#8056)

Release 1.72.2
Release 1.71.3
Release 1.72.1
Release 1.71.2
Bug Fixes
- client: HTTP Proxy connections are no longer attempted for addresses with non-TCP network types. (#8215)
Release 1.72.0
Dependencies
- Minimum supported Go version is now 1.23 (#8108)
API Changes
- resolver: add experimental
AddressMapV2with generics to ultimately replaceAddressMap. DeprecateAddressMapfor deletion (#8187) - resolver: convert EndpointMap in place to use generics (#8189)
New Features
- xds: add
grpc.xds_client.server_failurecounter metric on xDS client to record connectivity errors (#8203) - balancer/rls: allow
maxAgeto exceed 5 minutes ifstaleAgeis set in the LB policy configuration (#8137) - ringhash: implement gRFC A76 improvements. (#8159)
- pickfirst: The new pick first LB policy is made the default. The new LB policy implements the Happy Eyeballs algorithm. To disable the new policy set the environment variable
GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRSTtofalse(case insensitive).
Bug Fixes
- xds: fix support for circuit breakers and load reporting in LOGICAL_DNS clusters (#8169, #8170)
- xds/cds: improve RPC error messages when resources are not found (#8122)
- balancer/priority: fix race that could leak balancers and goroutines during shutdown (#8095)
- stats/opentelemetry: fix trace attributes message sequence numbers to start from 0 (#8237)
- balancer/pickfirstleaf: fix panic if deprecated Address.Metadata field is set to a non-comparable value by ignoring the field (#8227)
Behavior Changes
- transport: make servers send an HTTP/2 RST_STREAM frame to cancel a stream when the deadline expires (#8071)
Documentation
- stats: clarify the expected sequence of events on a stats handler (#7885)

Release 1.71.1
Bug Fixes
- grpc: fix a bug causing an extra Read from the compressor if a compressed message is the same size as the limit. This could result in a panic with the built-in gzip compressor (#8178)
- xds: restore the behavior of reading the bootstrap config before creating the first xDS client instead of at package init time (#8164)
- stats/opentelemetry: use
TextMapPropagatorandTracerProviderfromTraceOptionsinstead of OpenTelemetry globals (#8166) - client: fix races when an http proxy is configured that could lead to deadlocks or panics (#8195)
- client: fix bug causing RPC failures with message "no children to pick from" when using a custom resolver that calls the deprecated
NewAddressAPI (#8149) - wrr: fix slow processing of address updates that could result in problems including RPC failures for servers with a large number of backends (#8179)
