+=====================================================
+Breaking: #65165 - AdditionalMethodsInFolderInterface
+=====================================================
+
+Description
+===========
+
+The interface ``AdditionalMethodsInFolderInterface`` has received two additional methods. Classes that implement
+``FolderInterface`` have to implement those methods as well. The new methods are:
+
+* ``getModificationTime()`` - Returns the modification time of the folder as Unix timestamp.
+* ``getCreationTime()`` - Returns the creation time of the folder as Unix timestamp.
+
+
+Impact
+======
+
+Classes implementing the ``FolderInterface`` no longer fulfill the requirements of the interface.
+
+
+Affected Installations
+======================
+
+Installations that use custom implementations of the ``FolderInterface``.
+
+
+Migration
+=========
+
+Implement the two new methods in custom implementations of the ``FolderInterface``.
