List changes from beta 1 to beta 3?

Were there changes to ion-list from beta 1 to beta 3. My list isn’t styled properly anymore and the option buttons no longer work. Worked perfectly under Beta 1.

    <ion-list can-swipe="true" option-buttons="optionButtons" ng-show="tickets.length > 0">
      <ion-item ng-repeat="ticket in tickets" item="ticket" item-type="item-text-wrap ticket-item" href="#/tab/{{ view.url }}/ticket/{{ticket.id}}">

There were some big changes between the two.

This

<ion-list option-buttons="[{text:'hello',type:'button-positive',onTap:tap()}]"
          on-delete="onDelete(el)"
          delete-icon="ion-minus-circled"
          can-delete="true"
          show-delete="shouldShowDelete"
          on-reorder="onReorder(el, startIndex, toIndex)"
          reorder-icon="ion-navicon"
          can-reorder="true"
          show-reorder="shouldShowReorder">
  <ion-item ng-repeat="item in items">
    {{item}}
  </ion-item>
</ion-list>

Becomes this

<ion-list show-delete="shouldShowDelete"
          show-reorder="shouldShowReorder">
  <ion-item ng-repeat="item in items">
    {{item}}
    <ion-delete-button class="ion-minus-circled"
                       ng-click="onDelete(item)">
    </ion-delete-button>
    <ion-reorder-button class="ion-navicon"
                       ng-click="onReorder(item, $fromIndex, $toIndex)">
    </ion-reorder-button>
    <ion-option-button class="button-positive" ng-click="tap()">
      Hello
    </ion-option-button>
  </ion-item>
</ion-list>
