+#### Arguments in Component Lifecycle Hooks
+
+##### until: 2.13.0
+##### id: ember-views.lifecycle-hook-arguments
+
+Previously, it was possible for component lifecycle hooks `didInitAttrs`, `didReceiveAttrs`, and `didUpdateAttrs` to receive arguments. However, this functionality was part of private API. Using the arguments is harmful to component performance, so they will trigger a deprecation. Alternative approaches for all three hooks are below:
+
+##### `didInitAttrs` arguments
+
+Since this lifecycle hook is [already deprecated](http://emberjs.com/deprecations/v2.x/#toc_ember-component-didinitattrs), we suggest taking this chance to address two deprecations at the same time.
+
+Imagine you have a component that stores a timestamp when it is initialized.
+
+Before:
+
+``` javascript
+Ember.Component.extend({
+  didInitAttrs({ attrs }) {
+    this.set('initialTimestamp', attrs.timestamp);
+  }
+});
+```
+
+After:
+
+``` javascript
+Ember.Component.extend({
+  init() {
+    this._super(...arguments);
+
+    this.set('initialTimestamp', this.get('timestamp'));
+  }
+});
+```
+##### `didReceiveAttrs` and `didUpdateAttrs` arguments
+
+This example for `didReceiveAttrs` below also applies to `didUpdateAttrs`, a similar hook that only runs on re-renders. Let's say you want to animate a thermometer widget showing the change between today's high and low temperatures.
+
+Before:
+
+``` javascript
+Ember.Component.extend({
+  didReceiveAttrs({ oldAttrs, newAttrs }) {
+    if (oldAttrs.temp !== newAttrs.temp) {
+      this.thermometer.move({ from: oldAttrs.temp, to: newAttrs.temp });
+    }
+  }
+});
+```
+
+After:
+
+``` javascript
+Ember.Component.extend({
+  didReceiveAttrs() {
+    let highTemp = this.get('_highTemp');
+    let lowTemp = this.get('_lowTemp');
+
+    if (highTemp !== lowTemp) {
+      this.thermometer.move({ from: highTemp, to: lowTemp });
+    }
+  }
+});
+```
