-== New `+disabled+` option for disabling all user interactions
+=== Add Labels and Groups for Context Toolbar Buttons
+// #TINY-11095
+
+The release of {productname} {release-version} introduces the ability to organize context toolbar buttons into groups with optional labels or titles. This enhancement, available from {productname} 7.6.0 onward, improves toolbar usability by enabling clearer categorization of buttons.
+
+The `items` object structure now supports defining groups with an optional `name` property for titles or a `label` property for identifying the group. This feature allows developers to create more intuitive and accessible toolbars by visually segmenting functionality.
+
+Example of a context toolbar configuration with groups and labels:
+
+.Example
+[source,js]
+----
+items: [
+  {
+    name: 'Formatting', // Optional, used as the group's title
+    items: [ 'bold', 'italic' ] // Array of registered button names
+  },
+  {
+    label: 'History', // Optional, used as a label for the group
+    items: [ 'undo', 'redo' ] // Array of registered button names
+  },
+]
+----
+
+For more details on configuring context toolbar groups and labels, see: xref:contexttoolbar.adoc#add-labels-and-groups-for-context-toolbar-buttons[Context Toolbar].
+
+=== New `+disabled+` option for disabling all user interactions
 
 A new `+disabled+` option has been introduced to {productname} in version {release-version}. This option allows integrators to disable all user interactions with the editor, including cursor placement, content modifications, and UI components. When set to `+true+`, the editor behaves similarly to the readonly mode changes introduced in {productname} 7.4.0 but ensures complete non-interactivity.

+== Add labels and groups for context toolbar buttons
+
+From {productname} 7.6.0 onward, registering a context toolbar allows specifying `items` as an object that supports grouping with optional names and labels. This improvement enhances toolbar usability by organizing buttons into titled or labeled groups.
+
+The object structure takes two optional properties: `name` and `label`.
+
+* `name`: property is used as the group's title for the group that contains the buttons.
+* `label`: property is used as a label for each group of buttons.
+
+[NOTE]
+If neither `name` nor `label` is specified, the behavior defaults to ungrouped buttons.
+
+The object structure for `items` is as follows:
+
+.Example of a context toolbar configuration with groups and labels
+[source,js]
+----
+items: [
+  {
+    name: 'Formatting', // Optional, used as the group's title

+    items: [ 'undo', 'redo' ] // Array of registered button names
+  },
+  {
+    items: [ 'undo', 'italic' ] // No name or label specified, default behavior applies
+  }

 == Launching a context toolbar programmatically
 
 There is an `+editor+` event called `+contexttoolbar-show+` that can be fired to show a context toolbar at the current selection. The event takes a parameter `+toolbarKey+` which specifies the name of the registered context form or context toolbar to show.
