 **New API methods for dynamically updating an existing qgrid widget (as of 1.1.0)**:
 Adds the following new methods, which can be used to update the state of an existing Qgrid widget without having to call `show_grid` to completely rebuild the widget:
 
-    - `change_selection <https://qgrid.readthedocs.io/en/v1.1.0/#qgrid.QgridWidget.change_selection>`_
-    - `toggle_editable <https://qgrid.readthedocs.io/en/v1.1.0/#qgrid.QgridWidget.toggle_editable>`_
-    - `change_grid_option <https://qgrid.readthedocs.io/en/v1.1.0/#qgrid.QgridWidget.change_grid_option>`_ (experimental)
+    - `edit_cell <https://qgrid.readthedocs.io/en/latest/#qgrid.QgridWidget.edit_cell>`_
+    - `change_selection <https://qgrid.readthedocs.io/en/latest/#qgrid.QgridWidget.change_selection>`_
+    - `toggle_editable <https://qgrid.readthedocs.io/en/latest/#qgrid.QgridWidget.toggle_editable>`_
+    - `change_grid_option <https://qgrid.readthedocs.io/en/latest/#qgrid.QgridWidget.change_grid_option>`_ (experimental)

The following image shows qgrid displaying a multi-indexed DataFrame that was returned from Quantopian's `Pipeline API <https://www.quantopian.com/tutorials/pipeline?utm_source=github&utm_medium=web&utm_campaign=qgrid-repo>`_:
