As you publish 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
☝️ If you're on one of the deprecated personal plans, you can access up to 8 screen versions on the Growing Business plan, 4 screen versions on the Starter plan.
To unlock more screen versions, you can upgrade your plan from the Billing tab in your profile: https://app.zeplin.io/profile/billing.
