+
+Added a `migrateDocsCase()` method to TechDocs publishers, along with
+implementations for AWS, Azure, and GCS.
+
+This change is in support of a future update to TechDocs that will allow for
+case-insensitive entity triplet URL access to documentation pages which will
+require a migration of existing documentation objects in external storage
+solutions.
+
+See [#4367](https://github.com/backstage/backstage/issues/4367) for details.
