 ### Timeline
 
+- Implemented support for group templates (#996). Thanks @hansmaulwurf23.
+- Fixed #1076: Fixed possible overlap of minor labels text on the TimeAxis. 
 - Fixed #1001: First element of group style being cut.
 - Fixed #1071: HTML contents of a group not cleared when the contents is updated.
+- Fixed #1033: Moved item data not updated in DataSet when using an asynchronous
+  `onMove` handler.
+- Fixed #239: Do not zoom/move the window when the mouse is on the left panel
+  with group labels.
