@ -482,6 +482,7 @@ Changes
- add oneColumnModeClass option to grid.
- remove 768px CSS styles, moved to grid-stack-one-column-mode class.
- add max-width override on grid-stck-one-column-mode ([#462](https://github.com/troolee/gridstack.js/issues/462)).
- add internal function`isNodeChangedPosition`, minor optimization to move/drag.
#### v0.2.6 (2016-08-17)
