Every space ships with a page history option. Click the Page History icon {1} of your story to navigate to your page history.

By pressing the Page History button you will see your current, and all previous saved and published versions as a git style display of changes. Light blue means that an attribute was changed where the previous content is struck through, the currently active value will be shown after that. Green indicates an empty field was filled with content or a new field was added to the schema. Red stands for a delete, where one field or block was removed.

You can navigate between all your previous version by clicking on that version {1}. You can also restore to that version by clicking the Restore button {2}.

Once you click on the Restore button it will open a confirmation popup. You have two options you can click Restore {1} or if you want to go back, you can Cancel {2}.

After you click restore to a previous version just refresh the page and you will see your visual editor will show your previous content.
