The Modern List and Document Library Web Parts are new Office 365 features. You’ll begin seeing these new features over the coming weeks.
This message is associated with Office 365 Roadmap ID 83895.
How does this affect me?
The web parts can be added to any modern SharePoint page, allowing users to view and edit files directly from the web part. Any list or document library can be displayed and customized with the users’ own title, view, and size choice.
We’ll be gradually rolling this out in early May, and the roll out will be completed by the end of June 2017.
