ibute of the Ember framework is its use of <a href="http://semver.org/">Semantic Versioning</a> to aid projects in keeping up with
changes to the framework.  Before any functionality or API is removed it first goes through a deprecation period where the functionality is
still supported, but usage of it generates a warning logged to the browser console.  These warnings can pile up between major releases to a point where the amount of
deprecation warnings that scroll through the console becomes overwhelming.<
