Site Collection App Catalog is a new Office 365 feature for SharePoint Online. We’ll begin rolling this feature out in November.
This message is associated with Office 365 Roadmap ID 24254.
How does this affect me?
The Site Collection App Catalog provides the capability to delegate the installation of SharePoint Framework components to Site Collection owners in addition to managing them from the tenant app catalog. Access to this feature for individual site collections is controlled by the Tenant Admin, who adds a site to an allowed list of sites. Access to the feature can be revoked for a given site by removing it from the list.
When enabled for a given site, users with appropriate permissions can add and deploy SharePoint Framework components to their site collection. This enables web parts from the installed component to be used in modern and classic pages, and extensions in the component to be used on modern pages.
We’ll be gradually rolling this out to First Release customers in early November, and the roll out will be completed by the end of November.
