@@ -81,6 +81,7 @@ Here is an overview of all new **experimental** features:
 - **General**: Fix otelgrpc DoS vulnerability ([#5208](https://github.com/kedacore/keda/issues/5208))
 - **General**: Prevented memory leak generated by not correctly cleaning http connections ([#5248](https://github.com/kedacore/keda/issues/5248))
 - **General**: Prevented stuck status due to timeouts during scalers generation ([#5083](https://github.com/kedacore/keda/issues/5083))
+- **General**: ScaledObject Validating Webhook should support dry-run=server requests ([#5306](https://github.com/kedacore/keda/issues/5306))
 - **AWS Scalers**: Ensure session tokens are included when instantiating AWS credentials ([#5156](https://github.com/kedacore/keda/issues/5156))
 - **Azure Pipelines**: No more HTTP 400 errors produced by poolName with spaces ([#5107](https://github.com/kedacore/keda/issues/5107))
 - **GCP pubsub scaler**: Added `project_id` to filter for metrics queries ([#5256](https://github.com/kedacore/keda/issues/5256))
