Bellissima is the code name for the rebuild of the frontend code of the backoffice of Umbraco. Bellissima replaces the old deprecated AngularJS code with Lit, TypeScript and Web Components as well as a flexible extensions API.
Umbraco 17 has launched its Beta version, introducing a clearer pre-release process. This update features a new backoffice architecture, improved extensibility, and modern technology, transitioning from AngularJS to Web Components. The upgrade from Umbraco 13 to 17 is significant but manageable, ensuring a stable, future-proof platform for developers and users.
