 # Upgrade Notes
 
+#### v2.0.0
+Added `bool` as possible type to `$condition` parameter of `addCondition` function in `ProductListInterface` (and all implementing classes).
+
 #### v1.2.1
 - Removed the package "rybakit/twig-deferred-extension". If you extend the twig layout from the E-Commerce Framework, 
   please check if custom CSS/JS code added by `pimcore_head_script` and `pimcore_head_link` is still working.
