+## Istio Updated to Version 1.24.1 
+
+| **Component** | **Version** |
+|---------------|-------------|
+| Istio         | 1.24.1      |
+| Envoy         | 1.32.2      |
+
+We've updated the Istio version to 1.24.1 ([#1024](https://github.com/kyma-project/istio/pull/1024)).
+Read the [Istio 1.24.1 release announcement](https://istio.io/latest/news/releases/1.24.x/announcing-1.24.1/)
+and [Istio 1.24.0 Change Notes](https://istio.io/latest/news/releases/1.24.x/announcing-1.24/change-notes/).
+
+This version includes changes to compatibility version parameters. See the parameters for the previous compatibility version switched from `false` to `true`:
+
+| Parameter                            | Description                                                                                                                                                                         |
+|--------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| **ENABLE\_DELIMITED\_STATS\_TAG\_REGEX** | If true, pilot uses the new delimited stat tag regex to generate Envoy stats tags.                                                                                              |
+| **ENABLE\_DEFERRED\_CLUSTER\_CREATION**  | If enabled, Istio creates clusters only when there are requests. This saves memory and CPU cycles in cases where there are lots of inactive clusters and more than one worker thread. |
+
+This compatibility version applies the following new parameters set to `false`:
+
+| Parameter                                             | Description                                                                                                                                        |
+|-------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------|
+| **ENABLE\_INBOUND\_RETRY\_POLICY**       | If true, enables retry policy for inbound routes, which automatically retries any requests that were reset before reaching the intended service.                                                |
+| **EXCLUDE\_UNSAFE\_503\_FROM\_DEFAULT\_RETRY**            | If true, excludes unsafe retry on `503` from the default retry policy.                                                                                   |
+| **PREFER\_DESTINATIONRULE\_TLS\_FOR\_EXTERNAL\_SERVICES** | If true, external services prefer the TLS settings from DestinationRules over the metadata TLS settings.                                      |
+| **ENABLE\_ENHANCED\_DESTINATIONRULE\_MERGE**              | If enabled, Istio merges DestinationRules based on their **exportTo** fields. The DestinationRules are then kept as independent rules if the **exportTo** fields are not equal. |
+| **PILOT\_UNIFIED\_SIDECAR\_SCOPE**                        | If true, unified SidecarScope creation is used. This is only intended as a temporary feature flag for backward compatibility.                |
+| **ENABLE\_DEFERRED\_STATS\_CREATION**                     | If enabled, Istio lazily initializes a subset of the stats.                                                                                    |
+| **BYPASS\_OVERLOAD\_MANAGER\_FOR\_STATIC\_LISTENERS**     | If enabled, the overload manager is not applied to static listeners.                                                                              |

 ## New Features
-- Add zone-based podAntiAffinity rules for the `istio-ingressgateway` and `istiod` Deployments. [#1127](https://github.com/kyma-project/istio/pull/1127)
+
+We've added zone-based **podAntiAffinity** rules for the `istio-ingressgateway` and `istiod` Deployments. This change enhances resiliency and availability in the event of node-level or zone-level failures. ([#1127](https://github.com/kyma-project/istio/pull/1127))
