+This release ships a few changes in the API paths. Requests and responses were
+not changed. However, we did A LOT of internal refactoring and improvements on
+the persistence layer. Some naming in the SDKs changed, it is a lot cleaner now.
+One important change is that we removed the single table migrator. From now on
+to migrate from v0.6.0-alpha.1, please first migrate the legacy namespaces using
+v0.8.0-alpha.2 We also overhauled the whole persistence structure to ensure high
+scalability. This means that the migration might take a bit longer than usual,
+so please test the process first on a backup or staging environment. For all the
+details, check out the
+[full changelog](https://github.com/ory/keto/blob/master/CHANGELOG.md).
