[Compare Source](https://redirect.github.com/grpc/grpc-go/compare/v1.72.2...v1.73.0)

### New Features

-   balancer/ringhash: move LB policy from xds/internal to exported path to facilitate use without xds ([#&#8203;8249](https://redirect.github.com/grpc/grpc-go/issues/8249))
-   xds: enable least request LB policy by default. It can be disabled by setting `GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST=false` in your environment. ([#&#8203;8253](https://redirect.github.com/grpc/grpc-go/issues/8253))
-   grpc: add a `CallAuthority` Call Option that can be used to overwrite the http `:authority` header on per-RPC basis. ([#&#8203;8068](https://redirect.github.com/grpc/grpc-go/issues/8068))
-   stats/opentelemetry: add trace event for name resolution delay. ([#&#8203;8074](https://redirect.github.com/grpc/grpc-go/issues/8074))
-   health: added `List` method to gRPC Health service. ([#&#8203;8155](https://redirect.github.com/grpc/grpc-go/issues/8155))
    -   Special Thanks: [@&#8203;marcoshuck](https://redirect.github.com/marcoshuck)
-   ringhash: implement features from gRFC A76. ([#&#8203;8159](https://redirect.github.com/grpc/grpc-go/issues/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`. ([#&#8203;8167](https://redirect.github.com/grpc/grpc-go/issues/8167), [#&#8203;8180](https://redirect.github.com/grpc/grpc-go/issues/8180), [#&#8203;8229](https://redirect.github.com/grpc/grpc-go/issues/8229), [#&#8203;8343](https://redirect.github.com/grpc/grpc-go/issues/8343))

### Bug Fixes

-   xds: locality ID metric label is changed to make it consistent with [gRFC A78](https://redirect.github.com/grpc/proposal/blob/master/A78-grpc-metrics-wrr-pf-xds.md#optional-xds-locality-label). ([#&#8203;8256](https://redirect.github.com/grpc/grpc-go/issues/8256))
-   client: fail RPCs on the client when using extremely short contexts that expire before the `grpc-timeout` header is created. ([#&#8203;8312](https://redirect.github.com/grpc/grpc-go/issues/8312))
-   server: non-positive `grpc-timeout` header values are now rejected. This is consistent with the [gRPC protocol spec](https://redirect.github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md#requests). ([#&#8203;8290](https://redirect.github.com/grpc/grpc-go/issues/8290))
    -   Special Thanks: [@&#8203;evanj](https://redirect.github.com/evanj)

-   server: improve performance of RPC handling by avoid a status proto copy ([#&#8203;8282](https://redirect.github.com/grpc/grpc-go/issues/8282))
    -   Special Thanks: [@&#8203;evanj](https://redirect.github.com/evanj)

### Documentation
