  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

    <one line to give the program's name and a brief idea of what it does.>

- Kubeadm: make sure the etcd static pod startup probe uses /health?serializable=false while the liveness probe uses /health?serializable=true&exclude=NOSPACE. The NOSPACE exclusion would allow administrators to address space issues one member at a time.

- Replace the url label of `rest_client_request_duration_seconds` and `rest_client_rate_limiter_duration_seconds` metrics with a host label to prevent cardinality explosions and keep only the useful information. This is a breaking change required for security reasons. ([#106539](https://github.com/kubernetes/kubernetes/pull/106539), [@dgrisonnet](https://github.com/dgrisonnet))

- Service load balancers no longer exclude nodes marked unschedulable from the candidate nodes. The service load balancer exclusion label should be used instead.
  

    *   Select and scatter in reference util and evaluator now use
        lexicographical order to break ties.
*   TensorFlow Debugger (tfdbg) CLI:
    *   During tensor-filter operations, allow exclusion of nodes by regular
        expressions.
    *   Fix spurious background colors in some text terminals.
*   `tf.contrib`:
    *   Add meta-distribution BatchReshape which reshapes batch dimensions.
