 # Changelog
 
 ## Unreleased
 
+## 3.0.0
+
+### Breaking changes
+
+The search user experience is now more accessible for screenreader users. Search results are now on a separate page instead of a modal window.
+
+Users can no longer see search results as they type. They must press the Return key or select the search button to see the search results page.
+
+This was added in [pull request #263: Change search to only show results after submit](https://github.com/alphagov/tech-docs-gem/pull/263).
