File handlers 2.0 are new Office 365 extensibility features. We’ll begin rolling these features out in the next few days.
How does this affect me?
File handlers 2.0 provide additional options for developers to integrate their solutions into OneDrive for Business and SharePoint Online. Using file handlers, developers can build apps that provide custom file experiences for their file types and light up new actions and activities inside the OneDrive experience.
While no immediate changes will be visible to your users, over time, new applications will start to light up when you connect applications with OneDrive for Business or SharePoint Online.
We’ll begin rolling these features out in the next few days, and the roll out will be completed by the end of September.
