 ## Filtering Deprecations
 
-When your project has a lot of deprecations, you can start by filtering out deprecations that do not have to be addressed right away.  You
-can use the [deprecation handlers](https://emberjs.com/api/ember/2.15/classes/Ember.Debug/methods/registerDeprecationHandler?anchor=registerDeprecationHandler) API to check for what
-release a deprecated feature will be removed.  An example handler is shown below that filters out all deprecations that are not going away
-in release 2.0.0.

 ## Deprecation Workflow

-deprecations may only occur in very specific scenarios that are not obvious.  How then should you go about finding and fixing these?  This

 To collect deprecations, first run your in-browser test suite by starting your development server and navigating to [`http://localhost:4200/tests`](http://localhost:4200/tests).  If your test suite isn't fully covering your app's functionality, you may also
 manually exercise functionality within your app where needed.  Once you've exercised the app to your satisfaction, run the following command within
