History

With the History tool, you can track changes to your notebooks and revert to recorded states. It uses default and custom checkpoints:

Default checkpoints are automatically added for such events as: creating the notebook, adding or deleting a sheet, and deleting a cell.
Custom checkpoints are added manually by the notebook owner or users with edit access.

Notebook history can be viewed by users with both access types, but viewers cannot revert notebooks.

Select Tools | History from the main menu.
In the History tool, view notebook states by selecting checkpoints from the list.
For every checkpoint, the input differences between the selected state and the current version are shown.
(Optional) You can choose between the two viewer types and select whether you want to see the unchanged cells.

Open the History tool.
Select the checkpoint for the required state. The revert icon will appear for the selected list item.
Click the revert icon.
Click OK in the Confirmation dialog to finish the procedure.

A new checkpoint is added to the top of the list under the name Revert to [selected_checkpoint].

Add custom checkpoints to save specific notebook states to its history.

Select Tools | Add history checkpoint from the main menu.
In the Enter checkpoint message dialog, provide a description for your checkpoint.
Click OK to close the dialog and finish the procedure.

Your new checkpoint is added and can be found using the History tool.
