+## Changelog since v1.18.0-alpha.1
+
+## Urgent Update Notes
+
+## Changes by Kind
+
+### API Changes
+None.
+
+### Features & Enhancements
+- `karmada-operator`: Aligned with [recommendations from SIG instrumentation](https://github.com/kubernetes/community/blob/main/contributors/devel/sig-instrumentation/logging.md#how-to-log), when provisioning a Karmada instance, the operator now sets the default verbosity level for the following components to 2: `karmada-webhook`, `kube-controller-manager`, `karmada-controller-manager`, `karmada-scheduler`, `karmada-apiserver`, and `karmada-descheduler`. ([#7352](https://github.com/karmada-io/karmada/pull/7352), @jabellard)
+- `karmada-webhook`: Added validation for `spec.overriders.fieldOverrider` in `OverridePolicy` and `ClusterOverridePolicy` to ensure that a `FieldOverrider` must have either JSON or YAML set. ([#7365](https://github.com/karmada-io/karmada/pull/7365), @Denyme24)
+- `karmadactl`: Aligned with [recommendations from SIG instrumentation](https://github.com/kubernetes/community/blob/main/contributors/devel/sig-instrumentation/logging.md#how-to-log), when provisioning a Karmada instance, `karmadactl` now sets the default verbosity level to 2 for the following components: `karmada-apiserver`, `karmada-aggregated-apiserver`, `karmada-controller-manager`, `karmada-scheduler`, `karmada-webhook`, `karmada-agent`, `karmada-descheduler`, and `kube-controller-manager`. Users can override the default via `--<component>-extra-args="--v=<level>"`. ([#7356](https://github.com/karmada-io/karmada/pull/7356), @seanlaii)
+
+### Deprecation
+None.
+
+### Bug Fixes
+- `karmada-controller-manager`: Fixed `ClusterTaintPolicyController` silently dropping concurrent cluster health taints (`not-ready:NoSchedule`, `unreachable:NoSchedule`) during taint patches, which could cause workloads to be scheduled onto degraded clusters. ([#7348](https://github.com/karmada-io/karmada/pull/7348), @Ady0333)
+- `karmada-controller-manager`: Fixed the issue that `Job` completions were assigned to the wrong replicas for each cluster. ([#7387](https://github.com/karmada-io/karmada/pull/7387), @Ady0333)
+- `karmada-operator`: Fixed init reconciliation failure by replacing non-idempotent secret creation with an idempotent approach. ([#7358](https://github.com/karmada-io/karmada/pull/7358), @qiuming520)
+- `karmada-scheduler`: Fixed incorrect error type propagation that caused bindings with insufficient cluster replicas to be misrouted to `backoffQ` instead of `unschedulableBindings`, changing retry behavior from exponential backoff (1–10s) to timer-based retry (5 minutes). ([#7340](https://github.com/karmada-io/karmada/pull/7340), @seanlaii)
+
+### Security
+None.
+
+## Other
+
+### Dependencies
+None.
+
+### Helm Charts
+- `Helm chart`: Added helm index for `v1.17.1`. ([#7351](https://github.com/karmada-io/karmada/pull/7351), @github-actions)
+- `Helm chart`: Aligned with recommendations from SIG instrumentation, the Helm chart now sets the default verbosity level to 2 for the following components: `karmada-apiserver`, `karmada-aggregated-apiserver`, `karmada-controller-manager`, `karmada-scheduler`, `karmada-webhook`, `karmada-agent`, `karmada-descheduler`, `kube-controller-manager`, `karmada-search`, `karmada-metrics-adapter`, and `karmada-scheduler-estimator`. ([#7372](https://github.com/karmada-io/karmada/pull/7372), @SujoyDutta)
