## Urgent Upgrade Notes

### Bug or Regression

image requiring credential verification is always pulled if authentication information from an image pull is not yet present, thus enforcing authentication / re-authentication. This means an image pull might be attempted even in cases where a pod requests the `IfNotPresent` image pull policy, and might lead to the pod not starting if its pull policy is `Never` and is unable to present authentication information that led to a previous successful pull of the image it is requesting.

- Scheduler now skips the `NodeAffinity Score` plugin when it has nothing to do with a Pod. You might have noticed an increase in the metric `plugin_execution_duration_seconds` for `extension_point=score` and `plugin=NodeAffinity`, because the plugin only runs when it's relevant.

//   materialized in the address space of the calling process.
// * int is used as an index into arrays.
// * Deletion functions are safe to call on nullptr.
//
// Questions left to address:
// * Might at some point need a way for callers to provide their own Env.
// * Maybe add TF_TensorShape that encapsulates dimension info.
//
// Design decisions made:
// * Backing store for tensor memory has an associated deallocation

### Bug or Regression

- Fixes a race condition in the iptables mode of kube-proxy in 1.27 and later
  that could result in some updates getting lost (e.g., when a service gets a
  new endpoint, the rules for the new endpoint might not be added until
  much later). ([#122757](https://github.com/kubernetes/kubernetes/pull/122757), [@hakman](https://github.com/hakman)) [SIG Network]
