     - [ ] Tests are passing.
-    - [ ] The deprecated version renders on staging as expected.
-    - [ ] The new oldest supported version renders on staging as expected. Also check the banner text.
-- [ ] Remove the outdated Liquid markup and frontmatter. It's recommended to create a topic branch off of your `deprecate-<version>` branch to isolate the changes for review.

You should also be able to navigate to a page that is available in the deprecated version and change the version in the URL to the deprecated version, to test redirects.
