Version specific documentation for upgrading to new major versions of Umbraco Forms.

This article provides specific upgrade documentation for migrating to Umbraco Forms version 14.

If you are upgrading to a minor or patch version, you can find the details about the changes in the Release Notes article.

Version Specific Upgrade Notes History

Version 14 of Umbraco Forms has a minimum dependency on Umbraco CMS core of 14.0.0. It runs on .NET 8.

Breaking changes

Version 14 contains a number of breaking changes, primarily due to the new backoffice introduced in Umbraco 14. The details are listed here:

Behavior

• A new management API has been introduced at umbraco/forms/management/api.

• The root of the existing delivery API used for headless/AJAX solutions has moved to umbraco/forms/delivery/api.

• The HTML helper RenderUmbracoFormDependencies no longer renders the promises polyfill, which is not needed in modern browsers.

• Server-side registration of content apps has been removed as this is now a client-side concern.

• Creation of custom fields, workflow, and other provider types remains primarily a server-side task. However, they no longer require the provision of AngularJS views and controllers. Instead, these reference registered client-side manifests. For more information, see the extending Umbraco Forms article.

• With the removal of node selection by XPath support in Umbraco 14, the "Save as Umbraco node" workflow now uses dynamic root.

Configuration

• The setting FieldSettings:TitleAndDescription:AllowUnsafeHtmlRendering has a new default of false.

• The setting PageOptions:TrackRenderedFormsStorageMethod has a new default of HttpContextItems.

Dependencies

• Umbraco CMS dependency was updated to 14.0.0.

Code

The following updates describe the more significant changes to the codebase and public API:

• All controllers relating to backoffice trees and editors have been removed and their functionality replaced by the management API.

• The serialization library has been changed from Newtonsoft.Json to System.Text.Json. Among other updates this involved removing the public class FormsJsonSerializerSettings and replacing it with FormsJsonSerializerOptions.

• The obsolete methods GetFieldsNotDisplayed and Build on FormViewModel have been removed.

• The unused RetryWorkflow class has been removed.
