Release 1.69.2

Bug Fixes

• stats/experimental: add type aliases for symbols (Metrics/etc) that were moved to the stats package (#7929).
• client: set user-agent string to the correct version.

Release 1.69.0

Known Issues

• The recently addedgrpc.NewClient function is incompatible with forward proxies, because it resolves the target hostname on the client instead of passing the hostname to the proxy. A fix is expected to be a part of grpc-go v1.70. (#7556)

New Features

• stats/opentelemetry: Introduce new APIs to enable OpenTelemetry instrumentation for metrics on servers and clients (#7874)
• xdsclient: add support to fallback to lower priority servers when higher priority ones are down (#7701)
• dns: Add support for link local IPv6 addresses (#7889)
• The new experimentalpickfirst LB policy (disabled by default) supports Happy Eyeballs, interleaving IPv4 and IPv6 address as described inRFC-8305 section 4, to attempt connections to multiple backends concurrently. The experimentalpickfirst policy can be enabled by setting the environment variableGRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST totrue. (#7725,#7742)
• balancer/pickfirst: Emit metrics from thepick_first load balancing policy (#7839)
• grpc: exportMethodHandler, which is the type of an already-exported field inMethodDesc (#7796)
  • Special Thanks:@​mohdjishin

Bug Fixes

• credentials/google: set scope for application default credentials (#7887)
  • Special Thanks:@​halvards
• xds: fix edge-case issues where some clients or servers would not initialize correctly or would not receive errors when resources are invalid or unavailable if another channel or server with the same target was already in use . (#7851,#7853)
• examples: fix the debugging example, which was broken by a recent change (#7833)

Behavior Changes

• client: update retry attempt backoff to apply jitter per updates togRFC A6. (#7869)
  • Special Thanks:@​isgj
• balancer/weightedroundrobin: use thepick_first LB policy to manage connections (#7826)

API Changes

• balancer: An internal method is added to thebalancer.SubConn interface to force implementors to embed a delegate implementation. This requirement is present in the interface documentation, but wasn't enforced earlier. (#7840)

Performance Improvements

• mem: implement aReadAll() method for more efficientio.Reader consumption (#7653)
  • Special Thanks:@​ash2k
• mem: use slice capacity instead of length to determine whether to pool buffers or directly allocate them (#7702)
  • Special Thanks:@​PapaCharlie

Documentation

• examples/csm_observability: Add xDS Credentials and switch server to be xDS enabled (#7875)

Release 1.68.2
