+## Go libraries compatibility policy
+
+Tekton Pipelines may introduce breaking changes to its Go client libraries, as long as these changes
+do not impact users' yaml/json CRD definitions. For example, a change that renames a field of a CRD
+would need to follow the policy on [backwards incompatible changes](#backwards-incompatible-changes),
+but a change that renames the Go struct type for that field is allowed.
