+## Dimension integration manager has been removed from the playbook
+
+The [Dimension integration manager](./docs/configuring-playbook-dimension.md) has been removed from the playbook, as it has been unmaintained.
+
+The playbook will let you know if you're using any `matrix_dimension_*` variables. You'll need to remove them from `vars.yml` and potentially [uninstall the component manually](./docs/configuring-playbook-dimension.md#uninstalling-the-component-manually).
