+* Added a way of renaming pipeline resources while preserving version history by updating the resource name (as well as any reference in steps) and specifying its old name as [**`old_name`**](https://concourse-ci.org/resources.html#schema.resource.old_name). After the pipeline has been configured, the `old_name` field can be removed. #5833
