 ### Added
 
+- Use visibility of container definition or module for generated CRD enum ([#923]).
 - Add support to apply the `#[versioned()]` macro to modules to version all contained items at
   once ([#891]).
 - Add support for passing a `status`, `crates`, and `shortname` arguments through to the `#[kube]`
