* Metadata of CustomResources is now pruned and schema-checked during deserialization of requests and when read from etcd. In the former case, invalid meta data is rejected, in the later it is dropped from the CustomResource objects.

- Scheduler alpha metrics binding_duration_seconds and scheduling_algorithm_preemption_evaluation_seconds are deprecated, Both of those metrics are now covered as part of framework_extension_point_duration_seconds, the former as a PostFilter the latter and a Bind plugin. The plan is to remove both in 1.21 ([#95001](https://github.com/kubernetes/kubernetes/pull/95001), [@arghya88](https://github.com/arghya88)) [SIG Instrumentation and Scheduling]

- Added new kubelet alpha feature `SeccompDefault`. This feature enables falling back to
  the `RuntimeDefault` (former `runtime/default`) seccomp profile if nothing else is specified
  in the pod/container `SecurityContext` or the pod annotation level. To use the feature, enable

m := map[int]int{a: 1, a: 2}  // m may be {2: 1} or {2: 2}: evaluation order between the two map assignments is not specified
n := map[int]int{a: f()}      // n may be {2: 3} or {3: 3}: evaluation order between the key and the value is not specified
</pre>
