 The `ember-2-legacy` addon will enable developers to selectively opt into continuing to use removed APIs until a time when they can migrate away from them.

+Developers should reference the [2.x series deprecation guide](https://www.emberjs.com/deprecations/v2.x/) to see which pieces of public API will be removed in 3.x and how to migrate.

+Public APIs to be removed in 3.0 are as follows:
+* `didInitAttrs` is removed and can be [replaced with `init`](https://www.emberjs.com/deprecations/v2.x/#toc_ember-component-didinitattrs)
+* One form of declaring an `observer` where dependent keys are stated after the callback (they should go before the callback as described in the [API docs](https://emberjs.com/api/ember/2.17/classes/@ember%2Fobject/methods/observer?anchor=observer))
+* Enumerable and Array `contains` should be [replaced with `includes`](https://www.emberjs.com/deprecations/v2.x/#toc_enumerable-contains)
+* Providing `{{link-to}}` with a param wrapped in a controller
+* Specifying `defaultLayout` to a component, rather than [layout](https://www.emberjs.com/deprecations/v2.x/#toc_ember-component-defaultlayout)
+* Using `Ember.Handlebars.SafeString` [instead of `Ember.String.htmlSafe`](https://www.emberjs.com/deprecations/v2.x/#toc_use-ember-string-htmlsafe-over-ember-handlebars-safestring)
+* `Ember.K` should be replaced with [inline functions](https://www.emberjs.com/deprecations/v2.x/#toc_deprecations-added-in-2-12)
