英文原文已经有了改动

1.英文原文的url改了 
2.在clearCompleted action中：
clearCompleted: function () {
    var completed = this.filterBy('isCompleted', true);
    completed.invoke('deleteRecord');

    this.get('store').commit();//*我查看了英文版这里
                               //改成了completed.invoke('save');
                               //原来的this.get('store').commit()                                                                                                             已经不能使用
