@mfojtik @smarterclayton the bump looks reasonable, although I'm yet to carefully go through every change. Let's see how our tests infra likes it.

@smarterclayton the big changes are: adding stats (grpc/grpc-go#961) and server list expiration (grpc/grpc-go#962).

Two experimental things added are: 1 the transport tap (grpc/grpc-go#968), 2. FailOnNonTempDialError (grpc/grpc-go#985), although that shouldn't bite us since you need to configure them separately.

So it looks like we should be kind of good.

The test error seems to be a known flake #11114. But

@smarterclayton @soltysh the diff looks scary, +4,355 −144 ? I still think that we should go with one cherry-pick to fix the issue and stay closer to upstream if possible.

The diff contains a quite a lot of .md files modifications. See one of my previous comments about the scope of the changes here.

Flake #15418.
