+
+A breaking change worth mentioning is related to style import. with ADF v5.0.0 an extra ```\lib``` is required.
+
+
+**example**:
+
+   previous versions of ADF :  ```@import '~@alfresco/adf-core/prebuilt-themes/adf-blue-orange.css';```
+    
+   starting ADF 5.0.0 : ```@import '~@alfresco/adf-core/lib/prebuilt-themes/adf-blue-orange.css';```
