 ## Breaking Changes
 
+`keto namespace migrate ...` commands were removed. To migrate from
+v0.6.0-alpha.1, please first migrate the legacy namespaces using v0.8.0-alpha.2
+
+The protobuf API was bumped to `v1alpha2`. Please upgrade your client dependency
+to that version. `v1alpha1` is still supported for now, but might be dropped
+soon.
+
+Some payload keys are now (not) required anymore. The generated SDKs will likely
+have breaking changes.

+
+  With this change Keto now maps strings to UUIDv5 on the storage layer. This
+  change allows unlimited strings to be used while maintaining good performance.
+  Further, it reduces the likeliness of database hot-spots. The migration that
+  applies this mapping might take some time, so please confirm that your
+  migration strategy works for you.
