## Urgent Upgrade Notes 

### (No, really, you MUST read this before you upgrade)

- Added support to the scheduler to start using QueueingHint registered for Pod/Updated event to determine whether unschedulable Pods update make them schedulable, when the feature gate `SchedulerQueueingHints` is enabled.

	maps.Copy(metric.Histogram, m.Histogram)
	return metric
}

// Get - returns cached value always upton the configured TTL,
// once the TTL expires "read()" registered function is called
// to return the new values and updated.
func (g *MetricsGroupV2) Get() (metrics []MetricV2) {
	m, _ := g.metricsCache.Get()
	if len(m) == 0 {

- Kubernetes API Go types removed runtime use of the `github.com/gogo/protobuf` library, and are no longer registered into the global gogo type registry. Kubernetes API Go types were not suitable for use with the `google.golang.org/protobuf` library, and no longer implement `ProtoMessage()` by default to avoid accidental incompatible use.
