+kind: NOTES
+body: 'all: This release contains new fields and structs for implmenting managed resource identity.
+  Resource identity is data that is defined by a separate schema and is stored alongside resource state.
+  Identity data is used by Terrform to uniquely identify a remote object and is meant to be immutable during
+  the remote object''s lifecycle. Resources that support identity can now be imported using the `identity` attribute
+  in Terraform configuration `import` blocks, available in Terraform v1.12+. The `resource.Identity` field on the `schema.Resource`
+  struct can be used to support identity by defining an identity schema. Once the identity schema is defined, you can read
+  and store identity data in the state file with the new `IdentityData` struct that is available via the `Identity()` method
+  on `schema.ResourceData` and `schema.ResourceDiff` structs.'
