As you export designs, Zeplin keeps track of changes made on each screen and displays them under the “Versions” panel.
Due to storage restrictions, the number of versions you can access varies depending on your plan:
Free: 30 days versions
Team: Unlimited versions
Organization: Unlimited versions
Enterprise: Unlimited versions
☝️ Those on the Growing Business plan have access to 8 versions; Starter plan subscribers can access up to 4 screen versions in their project.
