-Deprecated the `namespace` option for `createExtensionBlueprint` and `createExtension`, these are no longer required and will default to the `pluginId` instead
+Deprecated the `namespace` option for `createExtensionBlueprint` and `createExtension`, these are no longer required and will default to the `pluginId` instead.
+
+You can migrate some of your extensions that use `createExtensionOverrides` to using `createFrontendModule` instead and providing a `pluginId` there.
+
+```ts
+// Before
+createExtensionOverrides({
+  extensions: [
+    createExtension({
+      name: 'my-extension',
+      namespace: 'my-namespace',
+      kind: 'test',
+      ...
+    })
+  ],
+});
+
+// After
+createFrontendModule({
+  pluginId: 'my-namespace',
+  extensions: [
+    createExtension({
+      name: 'my-extension',
+      kind: 'test',
+      ...
+    })
+  ],
+});
+```
