#### **Audit**

* iSCSI sessions managed by kubernetes will now explicitly set startup.mode to 'manual' to  prevent automatic login after node failure recovery. This is the default open-iscsi mode, so this change will only impact users who have changed their startup.mode to be 'automatic' in /etc/iscsi/iscsid.conf. ([#57475](https://github.com/kubernetes/kubernetes/pull/57475), [@stmcginnis](https://github.com/stmcginnis))

* Add the `alpha.image-policy.k8s.io/failed-open=true` annotation when the image policy webhook encounters an error and fails open. ([#46264](https://github.com/kubernetes/kubernetes/pull/46264), [@Q-Lee](https://github.com/Q-Lee))

- Added a new metric `webhook_fail_open_count` to monitor webhooks that fail to open. ([#107171](https://github.com/kubernetes/kubernetes/pull/107171), [@ltagliamonte-dd](https://github.com/ltagliamonte-dd))

- An audit log entry will be generated when a `ValidatingAdmissionWebhook` is failing to open. ([#92739](https://github.com/kubernetes/kubernetes/pull/92739), [@cnphil](https://github.com/cnphil))
- Base images: Updated to
  - debian-base:buster-v1.6.0

- Panics while calling validating admission webhook are caught and honor the fail open or fail closed setting. ([#108746](https://github.com/kubernetes/kubernetes/pull/108746), [@deads2k](https://github.com/deads2k)) [SIG API Machinery]

Structured logging reached its Beta milestone. Most log messages from kubelet and kube-scheduler have been converted. Users are encouraged to try out JSON output or parsing of the structured text format and provide feedback on possible solutions for the open issues, such as handling of multi-line strings in log values.
