This report introduces the method for managing the histories of the Google Apps Script project.
On August 23, 2023, the project history has been implemented in the new IDE of Google Apps Script. In the current stage, the users can see the history of the previously deployed script version. … In the case of the classic IDE, the users had been able to see the previously saved script version regardless of the deployment and just the save of the script. This is not implemented in the new IDE.
In August 2023, Google updated the online Apps Script Editor adding a feature which lets you view previously deployed script versions and compare them to the current script version. A current limitation the history is limited to versioned deployments. As noted in this source post from Kanshi Tanaike, deployments require several steps and you have to remember to go through the process. To make the process easier Kanshi has published a ScriptHistoryApp library, which can be used to create a custom web interface for making your own Apps Script project version history. Perhaps more usefully you can also manage snapshots of your script projects by fetching a URL. This makes it easy for you to either regularly save a project on a timed trigger or an event based mechanism.
