SharePoint Framework is a new Office 365 feature. You’ll begin seeing this new feature over the coming weeks.
This message is associated with Office 365 Roadmap ID 48113.
How does this affect me?
At General Availability, usage of SharePoint Framework web parts within production SharePoint sites is now supported. Administrators can deploy SharePoint Framework Client-side Solutions via their App Catalog to make them available within their tenancy. Site owners can use SharePoint Framework client-side web parts in Classic and Modern pages.
What do I need to do to prepare for this change?
Developers who have been creating SharePoint Framework web parts should read the General Availability release notes to learn more about updates and changes with the General Availability version of the SharePoint Framework. Administrators can now deploy custom-developed SharePoint Framework parts, and site owners can use those parts within pages in SharePoint.
