Site Settings Versioning

With site versioning anytime someone changes any setting in site details or email settings of the site, the new settings get automatically stored in CMS as a pre-defined content item. This allows maintaining a history of changes to site settings. From the versioning history, you can also rollback to a previous version in case something went wrong.

To locate the versioned content item in CMS which stores the site changes, look for an item with name SiteProperties.json
