 # Release notes Shopware 6.6.10.0
@@ -17,7 +17,71 @@ This minor release contains
 * tested on MySQL 8 and MariaDB 10.11
 
 ## Improvements
+### Upgrade to Symfony 7.2
+* Changed `symfony/*` dependencies to `^7.2`
 
+### Bulk entity extension
+* Deprecated EntityExtension::getDefinitionClass. It will be replaced by `EntityExtension::getEntityName`, which needs to return the entity name.
+
+
+Before:
+
+```php
+<?php
+
+namespace Examples\Extension;
+
+use Shopware\Core\Content\Product\ProductDefinition;
+use Shopware\Core\Framework\DataAbstractionLayer\EntityExtension;
+
+class MyEntityExtension extends EntityExtension
+{
+    public function getDefinitionClass(): string
+    { 
+        return ProductDefinition::class;
+    }
+}
+```
+
+After:
+
+```php
+<?php
+
+namespace Examples\Extension;
+
+use Shopware\Core\Content\Product\ProductDefinition;
+use Shopware\Core\Framework\DataAbstractionLayer\EntityExtension;
+
+class MyEntityExtension extends EntityExtension
+{
+    public function getEntityName() : string
+    {
+        return ProductDefinition::ENTITY_NAME;
+    }
+}
+```
+
+### Using external URL for media's path without storing physical files
+* You can now store media paths as external URLs using the admin API. This allows for more flexible media management without the need to store physical files on the server.
+
+**Example Request:**
+
+```http
+POST http://sw.test/api/media
+Content-Type: application/json
+
+{
+    "id": "01934e0015bd7174b35838bbb30dc927",
+    "mediaFolderId": "01934ebfc0da735d841f38e8e54fda09",
+    "path": "https://test.com/photo/2024/11/30/sunflowers.jpg",
+    "fileName": "sunflower",
+    "mimeType": "image/jpeg"
+}
+```
+
+### Add aggregate admin api
+* Added generic `/api/aggregate/{entityName}` API. It is similar to already existing `/api/search/${entityName}`, but without loading entities
