### [`v1.74.2`](https://redirect.github.com/grpc/grpc-go/releases/tag/v1.74.2): Release 1.74.2

[Compare Source](https://redirect.github.com/grpc/grpc-go/compare/v1.74.1...v1.74.2)

### 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. ([#&#8203;8283](https://redirect.github.com/grpc/grpc-go/issues/8283))

### API Changes

-   balancer: add `ExitIdle` method to `Balancer` interface. Earlier, implementing this method was optional. ([#&#8203;8367](https://redirect.github.com/grpc/grpc-go/issues/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. ([#&#8203;8248](https://redirect.github.com/grpc/grpc-go/issues/8248))

-   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. ([#&#8203;8439](https://redirect.github.com/grpc/grpc-go/issues/8439))

### Bug Fixes

-   googledirectpath: avoid logging the error message `Attempt to set a bootstrap configuration...` when creating multiple directpath channels. ([#&#8203;8419](https://redirect.github.com/grpc/grpc-go/issues/8419))

### Performance Improvements

-   transport: reduce heap allocations by pooling objects and avoiding method-to-closure conversions. ([#&#8203;8361](https://redirect.github.com/grpc/grpc-go/issues/8361))
-   transport: reduce heap allocations by re-using `mem.Reader` objects. ([#&#8203;8360](https://redirect.github.com/grpc/grpc-go/issues/8360))

### Documentation

-   examples: add examples to demonstrate enabling experimental metrics using the OpenTelemetry plugin. ([#&#8203;8388](https://redirect.github.com/grpc/grpc-go/issues/8388))
