## Urgent Upgrade Notes 

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

---

Ejemplos comunes de operaciones limitadas por la CPU son cosas que requieren procesamiento matemático complejo.

Por ejemplo:

* **Procesamiento de audio** o **imágenes**.
* **Visión por computadora**: una imagen está compuesta de millones de píxeles, cada píxel tiene 3 valores / colores, procesar eso normalmente requiere calcular algo en esos píxeles, todos al mismo tiempo.

import jcifs.Address;
import jcifs.CIFSContext;
import jcifs.CIFSException;
import jcifs.DfsReferralData;
import jcifs.DialectVersion;
import jcifs.SmbConstants;
import jcifs.SmbTransport;
import jcifs.audit.SecurityAuditLogger;
import jcifs.internal.CommonServerMessageBlock;
import jcifs.internal.CommonServerMessageBlockRequest;
import jcifs.internal.CommonServerMessageBlockResponse;
import jcifs.internal.RequestWithPath;

Common examples of CPU bound operations are things that require complex math processing.

For example:

* **Audio** or **image processing**.
* **Computer vision**: an image is composed of millions of pixels, each pixel has 3 values / colors, processing that normally requires computing something on those pixels, all at the same time.

- `kube-apiserver` added:
  - `alpha` support (guarded by the `ServiceAccountTokenJTI` feature gate) for adding a `jti` (JWT ID) claim to service account tokens it issues, adding an `authentication.kubernetes.io/credential-id` audit annotation in audit logs when the tokens are issued, and `authentication.kubernetes.io/credential-id` entry in the extra user info when the token is used to authenticate.

- Audit events for API requests to deprecated API versions now include a `"k8s.io/deprecated": "true"` audit annotation. If a target removal release is identified, the audit event includes a `"k8s.io/removal-release": "<majorVersion>.<minorVersion>"` audit annotation as well. ([#92842](https://github.com/kubernetes/kubernetes/pull/92842), [@liggitt](https://github.com/liggitt))...

	var dctx context.Context
	dctx, z.decommissionCancelers[idx] = context.WithCancel(GlobalContext)
	z.poolMetaMutex.Unlock()

	// Generate an empty request info so it can be directly modified later by audit
	dctx = logger.SetReqInfo(dctx, &logger.ReqInfo{})

	if err := z.decommissionInBackground(dctx, idx); err != nil {
		decomLogIf(GlobalContext, err)
		decomLogIf(GlobalContext, z.DecommissionFailed(dctx, idx))

- Kube-apiserver: `--audit-log-version` and `--audit-webhook-version` now only support the default value of `audit.k8s.io/v1`. The v1alpha1 and v1beta1 audit log versions, deprecated since 1.13, have been removed. ([#108092](https://github.com/kubernetes/kubernetes/pull/108092), [@carlory](https://github.com/carlory))

Des exemples communs d'opérations "CPU bounds" sont les procédés qui requièrent des traitements mathématiques complexes.

Par exemple :

* Traitements d'**audio** et d'**images**.

- Added `auditAnnotations` to `ValidatingAdmissionPolicy`, enabling CEL to be used to add audit annotations to request audit events.
  Added `validationActions` to `ValidatingAdmissionPolicyBinding`, enabling validation failures to be handled by any combination of the warn, audit and deny enforcement actions. ([#115973](https://github.com/kubernetes/kubernetes/pull/115973), [@jpbetz](https://github.com/jpbetz))
