+### Update to GOV.UK Frontend v4.0.0
 
-This means if you have a query like `/link/to/something?query=true&hello=world` on your POST form action, and you submit the form, the URL query string will be present in the redirected URL.
+The new release of GOV.UK Frontend contains:
+- an iteration to the accordion component
+- guidance about other ‘breaking’ changes you should make to improve your service
 
-This is useful when:
+Check the [GOV.UK Frontend release notes](https://github.com/alphagov/govuk-frontend/releases/tag/v4.0.0) for changes you may need to make to ensure your prototype works.
 
-- You’re using the query string to set flash messages or return paths
-- You want to rely on explicitly what’s in the query string for a specific page, rather than saved data.
+This change was added in [#1195: Update the GOV.UK Prototype Kit to use GOV.UK Frontend v4.0.0](https://github.com/alphagov/govuk-prototype-kit/pull/1195).
