- VSphere releases less than 7.0u2 are deprecated as of v1.24. Please consider upgrading vSphere to 7.0u2 or above. vSphere CSI Driver requires minimum vSphere 7.0u2.

processes if an out-of-memory event occurs. This implementation has shortcomings: for `Guaranteed` pods, memory can not be fully reserved, and the page cache is at risk of being recycled. For `Burstable` pods, overcommitting memory (setting `request` less than `limit` ) could increase the risk of a container being killed when the Linux kernel detects an out of memory condition.

As an alpha feature, Kubernetes v1.22 can use the cgroups v2 API to control memory allocation and isolation. This...

- Until this release, the iscsi plugin was waiting 10 seconds for a path to appear in the device list. However this timeout is not enough, or is less than the default device discovery timeout in most systems, which prevents certain devices from being discovered. This timeout has been raised to 30 seconds, which should help to avoid mount issues due to device discovery. ([#78475](https://github....

- When scheduling a mixture of pods using ResourceClaims and others which don't, scheduling a pod with ResourceClaims impacts scheduling latency less.

### Feature

is unable to start in iptables mode because system requirements are not met
(kernel or iptables versions are insufficient), the kube-proxy will fall-back
to userspace mode. Kube-proxy is much more performant and less
resource-intensive in ‘iptables’ mode.

### Deprecation

- Pod priority and preemption enables Kubernetes scheduler to schedule more important Pods first and when cluster is out of resources, it removes less important pods to create room for more important ones. The importance is specified by priority.
