[jcdc-bot]

The upgrade from Umbraco CMS v13 to v14 is a major version with extensive and significant breaking changes. This is not a routine update and requires substantial planning, code refactoring, and potential content migration.

Key Breaking Changes:

• Complete Backoffice Rebuild: The backoffice UI has been entirely rebuilt, moving from AngularJS to a modern stack (Web Components, TypeScript). All custom property editors, dashboards, and other backoffice extensions built for v13 and earlier are incompatible and must be rewritten using the new Extension API.

• Macros Completely Removed: The Macro feature has been entirely removed in v14. Any site functionality or content relying on macros will break. A migration strategy is required to convert existing macros to alternatives like Block List or Block Grid components.

• Removal of Deprecated Features: Legacy property editors like 'Grid Layout' and 'Nested Content' have been removed. Content using these must be migrated to the more modern Block Grid and Block List editors.

• API and Code-level Changes:

  • There are significant changes to backend APIs, including the notification handling API for events.
  • A new headless-capable Management API has been introduced, which may affect existing integrations.
  • The client-side asset manager 'Smidge' has been removed, requiring changes to how frontend assets are handled in views.

• .NET Framework Update: Umbraco 14 requires .NET 8.

Recommendation:
This upgrade should be treated as a major project. Do not merge this change without a thorough analysis of the existing implementation. A detailed migration plan must be developed to address custom code, macros, and deprecated data types. Allocate significant time for development, refactoring, and testing.
