Template and Theme Export Enhancements
When you export a Lightning template or theme that has locked regions, the locked regions are maintained in the exported version. Previously, the regions were unlocked when users created a community or theme from the exported item. We also added a Publisher Name field for template and theme export, which appears in the Community Creation wizard and on AppExchange. Previously, we used your org name.
Where: This change applies to Lightning communities accessed through Lightning Experience and Salesforce Classic in Essentials, Enterprise, Performance, Unlimited, and Developer editions.
