### Release Notes

<summary>grpc/grpc-java</summary>

### [`v1.32.1`](https://togithub.com/grpc/grpc-java/releases/v1.32.1)

[Compare Source](https://togithub.com/grpc/grpc-java/compare/v1.31.1...v1.32.1)

#### API Changes

-   api: Removed deprecated method `ChannelBuilder.blockingExecutor()` ([#&#8203;7242](https://togithub.com/grpc/grpc-java/issues/7242)). There should not be any users as it was deprecated the first release it was available and was renamed `offloadExecutor()`.
-   grpclb: Make ATTR_LB_ADDRS public ([#&#8203;7230](https://togithub.com/grpc/grpc-java/issues/7230)). This is necessary to configure grpclb from a custom NameResolver

#### New Features

-   xds: perform header matching on concatenated multi-valued headers ([#&#8203;7215](https://togithub.com/grpc/grpc-java/issues/7215))
-   xds: add header matching special cases for hiding/exposing some gRPC headers ([#&#8203;7224](https://togithub.com/grpc/grpc-java/issues/7224)). The only gRPC header available for header matching is “content-type”.
-   xds: support load reporting all clusters option and fix actual report interval measurement ([#&#8203;7209](https://togithub.com/grpc/grpc-java/issues/7209)). If the LRS response enables send_all_clusters, the client side will report loads for all clusters it is currently using.

#### Bug Fixes

-   core, alts, cronet: Fix ByteBuffer covariant method usages ([#&#8203;7349](https://togithub.com/grpc/grpc-java/issues/7349)). When built with Java 9+, internal usages of ByteBuffer APIs may cause runtime breakage for dependent applications running with Java 8. This is fixed now.
-   core: Fixed a bug that RPC may hang when hedging is enabled with a throttling configuration ([#&#8203;7337](https://togithub.com/grpc/grpc-java/issues/7337))
-   netty: The environment variable `GRPC_EXPERIMENTAL_AUTOFLOWCONTROL=false` will now disable the BDP monitoring introduced in v1.30.0. This is intended to help diagnose a “too_many_pings” compatibility issue and will be removed once it is resolved. If you need to use the variable, please file an issue
-   benchmarks: Use correct classpath for scripts (the ones in the bin/ folder of the tar/zip), fixing NoClassDefFoundErrors. The classpath was probably broken starting in v1.30.
-   xds: routing policy should immediately update a picker that selects base on updated config ([#&#8203;7233](https://togithub.com/grpc/grpc-java/issues/7233))

#### Dependencies

-   netty: Upgrade to Netty 4.1.51 and tcnative 2.0.31
-   android, cronet: Drop support for android SDK versions older than 16 ([#&#8203;7253](https://togithub.com/grpc/grpc-java/issues/7253)). The minimum supported Android SDK version is 16.

### Updating meta-information for bleeding-edge SNAPSHOT release.
---


This PR was generated with [Release Please](https://github.com/googleapis/release-please).

)

Automatically perform a Java client library release when:
1. Only dependency updates are going out in the release since any releases containing bug fixes, build changes or new features should be supervised;
2. There are no outstanding/open dependency update pull requests in the repo. This is to avoid multiple/redundant releases;
3. It is a SNAPSHOT release which is automatically generated post regular release -- this requires no human supervision.

Testing done in 5 java-bigquery* client library repos. Example:
[chore: release 0.3.4 ](googleapis/java-bigqueryconnection#130)
[chore: release 0.3.5-SNAPSHOT](googleapis/java-bigqueryconnection#131)
