 **Breaking changes**:
 
+- **Page feedback**, or [User feedback] ([#1726]):
+  - Feedback-event attribute changes:
+    - Event `name` is `page_helpful`rather than`click`
+    - Event `value` for "yes" is 100 by default, rather than 1, allowing for
+      more response options in the future. To override the default set
+      `params.ui.feedback.max_value`.
 - SCSS: `@function prepend()` and file `assets/scss/support/_functions.scss`
   have been dropped. Instead use the more general SASS/SCSS list `join()`
   function ([#1385]).
