 This files describes API changes in core libraries and APIs,
 information provided here is intended especially for developers.
 
+=== 4.0 ===
+* Added function setScrollable in core/modal. This function can be used to set the modal's body to be scrollable or not
+  when the modal's height exceeds the browser's height. This is also supported in core/modal_factory through the
+  'scrollable' config parameter which can be set to either true or false. If not explicitly defined, the default value
+  of 'scrollable' is true.
+
 === 3.9 ===
 * Following function has been deprecated, please use \core\task\manager::run_from_cli().
