## Karmada v1.4 Release Notes
### What's New
#### #Declarative Resource Interpreter
The [Interpreter Framework](https://karmada.io/docs/next/userguide/globalview/customizing-resource-interpreter/) is designed for interpreting the structure of arbitrary resource types. It consists of `built-in` and `customized` interpreters, this release introduced another brand-new customized interpreter.
With the newly introduced `declarative` [interpreter](https://karmada.io/docs/userguide/globalview/customizing-resource-interpreter), users can quickly customize resource interpreters for both Kubernetes resources and CRD resources by the rules declared in the `ResourceInterpreterCustomization` API specification. Compared with the interpreter customized by the webhook, it gets the rules from the declarative specifications instead of requiring an additional webhook component.
The new command named `interpret` in the `karmadactl` could be used to test the rules before applying them to the system.
Some examples are provided to help users better understand how this interpreter can be used.
(Feature contributor: @jameszhangyukun @ikaven1024 @chaunceyjiang @XiShanYongYe-Chang @RainbowMango)
#### PropagationPolicy/ClusterPropagationPolicy priority
Users are now able to declare the priority for both `PropagationPolicy` and `ClusterPropagationPolicy`, a policy will be applied for the matched resource templates if there are no other policies with higher priority at the point of the resource template be processed.
The priority could be used by the system administrator to manage and control the policies. Refer to [Configure PropagationPolicy priority](https://karmada.io/docs/userguide/scheduling/resource-propagating#configure-propagationpolicy-priority) for more details.
(Feature contributor: @Garrybest @jwcesign)
#### Instrumentation improvement
This release enhanced observability significantly through metrics and events.
The metrics can be queried by the endpoint(`/metrics`) of each component using an HTTP scrap, and they are served in Prometheus format. And the events are reported to the relevant resource objects respectively.
Refer to [events](https://karmada.io/docs/reference/instrumentation/event) and [metrics](https://karmada.io/docs/reference/instrumentation/metrics) for more details.
(Feature contributor: @Poor12)
