A new revisions dialogue is now in beta for templates, coded files and custom modules within the Design Manager. Now you can see when someone edits a template, coded file, or custom module and who it was that made the change. You can also see visual changes to the template, coded file or custom module directly from the revision history.
HubSpot customers in the beta group now have access to this feature. Want to try it out for yourself? Join the beta group here.
