+===============================================================
+Feature: #92337 - Allow translatable labels for bookmark groups
+===============================================================
+
+See :issue:`92337`
+
+Description
+===========
+
+The user TSconfig `options.bookmarkGroups` option allows to configure the bookmark
+groups that can be accessed by the user. In addition to that, it's also possible
+to define custom labels for each group as simple :php:`string`. Extended TSconfig
+syntax now allows the LLL prefix for the use of language labels.
+
+
+Example
+=======
+
+.. code-block:: ts
+
+   options.bookmarkGroups.2 = LLL:EXT:sitepackage/Resources/Private/Language/locallang_be.xlf:bookmarkGroups.2
+
+
+Impact
+======
+
+It is now possible to use custom language labels for bookmark groups.
