+You might have noticed that sometimes when a new release of Ember is out some API documentation can disappear. This happens when code gets moved around in Ember, such as putting functions in their own modules, which makes it easy to make mistakes that impact the documentation parser. [@ef4](https://github.com/ef4) added [test coverage](https://github.com/emberjs/ember.js/pull/16910) for exactly these cases.
