beta. This enables a volume plugin to specify the maximum number of a given volume type per node as a function of the node characteristics (for example, a larger limit for larger nodes, a smaller limit for smaller nodes).

SIG Storage also worked on a number of [Container Storage Interface (CSI) features](https://github.com/kubernetes/enhancements/issues/178) this quarter in anticipation of moving support for CSI from beta to GA in the next Kubernetes release. This includes graduating the...

- 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

- 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 warnings to the Services API. Kubernetes now warns for Services in the case of:
  - IPv4 addresses with leading zeros
  - IPv6 address in non-canonical format (RFC 5952) ([#114505](https://github.com/kubernetes/kubernetes/pull/114505), [@aojea](https://github.com/aojea))

- Introduced a structured and versioned `v1alpha1` response format for the `flagz` endpoint. ([#134995](https://github.com/kubernetes/kubernetes/pull/134995), [@yongruilin](https://github.com/yongruilin)) [SIG API Machinery, Architecture, Instrumentation, Network, Node, Scheduling and Testing]

* When deleting an object with `--grace-period=0`, the client will begin a graceful deletion and wait until the resource is fully deleted.  To force deletion, use the `--force` flag.
