🚨 [Breaking change]: Remove the built-in Bootstrap 3 horizontal forms theme from Umbraco Forms

Umbraco Forms 19 removes the bootstrap3-horizontal theme, which was incompatible with Bootstrap 4 and 5, as Bootstrap 3 reached end-of-life in July 2019. Developers are advised to create custom themes for their Bootstrap versions. The change reduces maintenance and avoids misleading developers regarding theme compatibility.

🚨 [Breaking change]: Replace Pikaday with native HTML date input in the Umbraco Forms default theme

In Umbraco Forms 19, the Date field type transitions from using Pikaday and Moment.js to a native <input type="date">, enhancing performance and simplifying model binding. This change eliminates hidden shadow fields and third-party dependencies, ensuring consistent ISO date formatting across browsers. Custom themes must be updated accordingly.

🚨 [Breaking change]: Remove jQuery Validation support from Umbraco Forms client-side scripts

Umbraco Forms 19 removes the jQuery Validation alternative, making aspnet-client-validation the sole supported client-side validation framework. The legacy umbracoforms-conditions.js is also deleted, simplifying maintenance and eliminating jQuery dependencies. Users must update their sites to restore @Html.RenderUmbracoFormDependencies(Url) and remove jQuery validation scripts.
