- `oc describe quota` used has the same unit format as hard ([#102177](https://github.com/kubernetes/kubernetes/pull/102177),...

- The kubernetes repo now uses Go workspaces.  This should not impact end users at all, but does have impact for developers of downstream projects.  Switching to workspaces caused some breaking changes in the flags to the various k8s.io/code-generator tools.  Downstream consumers should look at staging/src/k8s.io/code-generator/kube_codegen.sh to see the changes. ([#123529](https://github.com/kubernetes/kubernetes/pull/123529), ...

     *   where multiple modules in the reactor have the same artifactId.
     * <p>
     * {@code -rf :artifactId} will pick up the first module which matches, but when multiple modules in the reactor
     *   have the same artifactId, effective failed module might be later in build reactor.

* Azure cloudprovider: Reduce the polling delay for all azure clients to 5 seconds. This should speed up some operations at the cost of some additional quota. ([#43699](https://github.com/kubernetes/kubernetes/pull/43699), [@colemickens](https://github.com/colemickens))
