+shared debug input bindings and access to the selected reporting mode.
+ConfigKit remains at v1.1.0.
+
+## Compatibility and upgrade
+
+Select `go.maximumdirect.net/ckconfig v0.6.0` with CommandKit core v0.6.0.
+The consumer minimum remains Go 1.27.0. See the
+[consumer guide](../../../../docs/consumers/guide.md#invocation-reporting)
+for the new core reporting and debug input APIs.
