As part of making your app upgrades as smooth as possible, the
Ember Inspector gathers deprecations, groups them, and displays them in a
way that helps in tackling them.

To view the list of deprecations, click on the `Deprecations` menu.

You can see the total number of deprecations next to the `Deprecations` menu.
You can also see the number of occurrences for each deprecation.

### Ember Cli Deprecation Sources

If you are using Ember Cli and have source maps enabled, you can see a
list of sources for each deprecation. In Chrome and Firefox devtools,
clicking on that source file will open the sources panel and take you to
the code that caused the deprecation message.

You can send the entire stack trace of the deprecation message to the
console by clicking on `Trace in the console`.

click on the "Transition Plan" link to go to a helpful guide on how to
upgrade on the Ember.js website.
