### SIG Azure

For 1.13 SIG Azure was focused on adding additional Azure Disk support for Ultra SSD, Standard SSD, and Premium Azure Files. Azure Availability Zones and cross resource group nodes were also moved from Alpha to Beta in 1.13.

### SIG Big Data

### Removal of several beta Kubernetes APIs

- Graduated pod scheduling gates to general availability.
  The `PodSchedulingReadiness` feature gate no longer has any effect, and the

- kube-apiserver: Promoted the  `ServiceAccountTokenNodeBinding` feature gate general availability. It is now locked to enabled. ([#129591](https://github.com/kubernetes/kubernetes/pull/129591), [@liggitt](https://github.com/liggitt)) [SIG Auth and Testing]

kubeadm, the cluster lifecycle building block, continues to receive features and stability work required for bootstrapping production clusters efficiently. kubeadm has promoted high availability (HA) capability to beta, allowing users to use the familiar `kubeadm init` and `kubeadm join` commands to [configure and...

Kubernetes primitives that our Cluster Federation control plane
supports, expanding the number of approaches taken to multi-cluster
management (beyond our initial Federation approach), and preparing
to release Federation for general availability ('GA').

*   Azure Load Balancer Auto Mode: Services can be annotated to allow auto selection of available load balancers and to provide specific availability sets that host the load balancers (for example, `service.beta.kubernetes.io/azure-load-balancer-mode=auto|as1,as2...`)

### **CLI**

#### **Kubectl**

    * This ensures that attachment and detachment of volumes is independent of any single nodes’ availability. Meaning, if a node or kubelet becomes unavailable for any reason, the volumes attached to that node will be detached so they are free to be attached to other nodes.

- Graduated the `ReadWriteOncePod` feature gate to `GA`. ([#121077](https://github.com/kubernetes/kubernetes/pull/121077), [@chrishenzie](https://github.com/chrishenzie))
- Graduated the following kubelet resource metrics to **general availability**:
  - `container_cpu_usage_seconds_total`
  - `container_memory_working_set_bytes`
  - `container_start_time_seconds`
  - `node_cpu_usage_seconds_total`
  - `node_memory_working_set_bytes`

- **Admission webhooks:** Admission webhooks are in widespread use as a Kubernetes extensibility mechanism and have been available in beta since the 1.9 release. The 1.16 release marks the graduation of admission webhooks to general availability (GA).
