### Release Notes

<details>
<summary>grpc/grpc-go (google.golang.org/grpc)</summary>

###
[`v1.70.0`](https://redirect.github.com/grpc/grpc-go/releases/tag/v1.70.0):
Release 1.70.0

[Compare
Source](https://redirect.github.com/grpc/grpc-go/compare/v1.69.4...v1.70.0)

### Behavior Changes

- client: reject service configs containing an invalid retryPolicy in
accordance with gRFCs
[A21](https://redirect.github.com/grpc/proposal/blob/master/A21-service-config-error-handling.md)
and
[A6](https://redirect.github.com/grpc/proposal/blob/master/A6-client-retries.md).
([#&#8203;7905](https://redirect.github.com/grpc/grpc-go/issues/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`.
([#&#8203;7949](https://redirect.github.com/grpc/grpc-go/issues/7949))
- experimental/credentials: experimental transport credentials are added
which don't enforce ALPN.
([#&#8203;7980](https://redirect.github.com/grpc/grpc-go/issues/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.
([#&#8203;8011](https://redirect.github.com/grpc/grpc-go/issues/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.
([#&#8203;7998](https://redirect.github.com/grpc/grpc-go/issues/7998))
    -   Special Thanks: [@&#8203;lqs](https://redirect.github.com/lqs)

### Documentation

- examples/features/gracefulstop: add example to demonstrate server
graceful stop.
([#&#8203;7865](https://redirect.github.com/grpc/grpc-go/issues/7865))
