- Added new flag `skipResourceFilters` to reports controller to enable/disable considering resource filters in the background (default value is `true`)
- Webhook is no longer updated to match `pods/ephemeralcontainers` when policy only specifies `pods`. If users want to match on `pods/ephemeralcontainers`, they must specify `pods/ephemeralcontainers` in the policy.
- Webhook is no longer updated to match `services/status` when policy only specifies `services`. If users want to match on `services/status`, they must specify `services/status` in the policy.
- Support upper case `Audit` and `Enforce` in `.spec.validationFailureAction` of the Kyverno policy, failure actions `audit` and `enforce` are deprecated and will be removed in `v1.11.0`.
- A new flag `backgroundScan` to enable/disable kyverno background scans (default value is `true`). When this is set to `false`, kyverno will not perform background scans and won't trigger continuous evaluation of policies.
- A new flag `admissionReports` to enable/disable kyverno admission reports (default value is `true`). When this is set to `false`, kyverno will not create admission reports.
- If both `backgroundScan` and `admissionReports` are set to `false` the entire reports system will be disabled.
- A new flag `reportsChunkSize` to split reports according to the number of results contained in the report (default value is `1000`). This can be disabled by setting the flag value to `0`.
- Deprecated `splitPolicyReport` flag, splitting reports per policy is always enabled, keeping it for backward compatibility, will be removed in future version.
-`ReportChangeRequest` and `ClusterReportChangeRequest` CRDs have been removed and replaced by `AdmissionReport`, `ClusterAdmissionReport`, `BackgroundScanReport` and `ClusterBackgroundScanReport` CRDs.
- A new flag `protectManagedResources` to enable kyverno managed resources protection (default value is `false`). When this is enabled, kyverno managed resources can only be modified or deleted by the controller.
- A new flag `maxReportChangeRequests` is added to the Kyverno main container, this flag sets the up-limit of reportchangerequests that a namespace can take, or clusterreportchangerequests if matching kinds are cluster-wide resources. The default limit is set to 1000, and it's recommended to configure it to a small threshold on large clusters. Here the large clusters are considered that a policy report has more than 1k results.
-`status.ready` of the policy is deprecated in favor of `policy.IsReady()`. The implementation was changed to use `status.conditions` that offer more flexibility. The `status.ready` will be kept for a couple of releases until we remove it in the future.
- Flags that were overlapping with config map based configuration were removed (`filterK8sResources`, `excludeGroupRole`, `excludeUsername`). They can now be configured using the config map only.
-`anyPattern` for Kyverno validate policies breaks in Kubernetes `v1.23.0`-`v1.23.2`, and the fix is being tracked by this [PR](https://github.com/kubernetes/kubernetes/pull/107688) and will be available in `v1.23.3`.
- To use `any/all` conditions for policies that use `preconditons` and `deny.conditions`, the user can go to this [resource](https://kyverno.io/docs/writing-policies/preconditions/#any-and-all-statements) as a good starting point.
- With the change of dynamic webhooks, the readiness of the policy is reflected by `.status.ready`, When ready, it means the policy is ready to serve the admission requests.
- To add a consistent style in flag names the following flags have been deprecated `webhooktimeout`, `gen-workers`,`disable-metrics`, `background-scan`, `auto-update-webhooks`, `profile-port`, `metrics-port` these will be removed in 1.6.0. The new flags are `webhookTimeout`, `genWorkers`, `disableMetrics`, `backgroundScan`, `autoUpdateWebhooks`,`profilePort`, `metricsPort` (#1991).
