 * `Alert` is more generic and you can mix and match any number of buttons/inputs
 * `Alert` and `ActionSheet` can take an array of buttons with `handlers`
 * Returning `false` from button handlers prevent the overlay from closing
+* `ActionSheet` buttons no longer use an index and only one handler
+* `ActionSheet` cancel and destructive buttons go within the `buttons` array, but with an added `style` property
+* An actionsheet's desctructive button renders in the order it was added to the array (we recommend it always goes first)
+* An actionsheet's cancel button will always be last, no matter where it is in the array
 * All overlays use `NavController` `present()`, similar to `push()`
 * A `Modal` uses an injected `ViewController` to dismiss itself
   and optionally pass data to modal's `onDismss()`

+##### ActionSheet Refactor

+Was:
+
+```
+import {ActionSheet} from 'ionic/ionic';
+
+@Page(...)
+class MyPage {
+constructor(actionSheet: ActionSheet) {
+  this.actionSheet = actionSheet;
+}
+doActionMenu() {
+  this.actionSheet.open({
+    buttons: [
+      { text: 'Archive' }
+    ],
+    titleText: 'Modify your album',
+    cancelText: 'Cancel',
+    cancel: function() {
+      console.log('Canceled clicked');
+    },
+    destructiveText: 'Delete',
+    destructiveButtonClicked: () => {
+      console.log('Delete clicked');

+    buttonClicked: function(index) {

+      return true;
+    }
