Revert to a previously saved version
Click the Revert link next to any version of your exploration to revert and go back to using that version. This change will now be recorded and added to your History under the list of changes.
Warning
When you revert to an older version, you will lose any unsaved changes in your exploration. If you think you might want to come back to your current version at some point later on, make sure you save your draft before reverting so that Oppia has a record of it.
Download a version
Click the Download link next to a version to download a zip file that will contain all the data for your exploration. It will include a YAML file as well as any additional asset files (such as images) that are part of your exploration. You can now share this file with other people if you wish.
