[BUGFIX release] Refine Ember Global deprecation message
Browse files Browse the repository at this point in the history 
Example message:

```
Usage of the Ember Global is deprecated. You should import the Ember module or the specific API instead.

See https://deprecations.emberjs.com/v3.x/#toc_ember-global for details.

Usages of the Ember Global may be caused by an outdated ember-cli-babel dependency. The following steps may help:

* Upgrade your `devDependencies` on `ember-cli-babel` to `^7.26.6`.
* Upgrade the following addons to the latest version:
  * active-model-adapter
  * ember-animated
  * ember-async-await-helper
  * ember-attacher
  * ember-cli-showdown
  * ember-freestyle
  * ember-md5

### Important ###

In order to avoid repeatedly showing the same deprecation messages, no further deprecation messages will be shown for usages of the Ember Global until ember-cli-babel is upgraded to v7.26.6 or above.

To see all instances of this deprecation message at runtime, set the `EMBER_GLOBAL_DEPRECATIONS` environment variable to "all", e.g. `EMBER_GLOBAL_DEPRECATIONS=all ember test`.

### Details ###

Prior to v7.26.6, ember-cli-babel sometimes transpiled imports into the equivalent Ember Global API, potentially triggering this deprecation message even when you did not directly reference the Ember Global.

The following outdated versions are found in your project:

Note: Addons marked as "Dormant" does not appear to have any JavaScript files. Therefore, even if they are using an old version ember-cli-babel, they are unlikely to be the cuplrit of this deprecation and can likely be ignored.

Note: Addons marked as "Compatible" are already compatible with [email protected]. Try upgrading your `devDependencies` on `ember-cli-babel` to `^7.26.6`.
