v1.70.0: Release 1.70.0

Compare Source

Behavior Changes

• client: reject service configs containing an invalid retryPolicy in accordance with gRFCs A21 and A6. (#​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. (#​7949)
• experimental/credentials: experimental transport credentials are added which don't enforce ALPN. (#​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. (#​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. (#​7998)
  • Special Thanks: @​lqs

Documentation

• examples/features/gracefulstop: add example to demonstrate server graceful stop. (#​7865)
