1.使用了物理约束的动画在导出PNG时无法根据模拟后图片的动幅定义最大尺寸。
2.使用了物理约束后难以应用到循环动画上，希望有烘焙选项，特别是针对循环动画的，谢谢(我目前的解决办法是设置三组循环取中间段）但还是希望以后可以优化这一问题
有关于4.209版本的部分缺陷

We will take your comments into consideration and hope you look forward to future updates as we still have some things we would like to improve in 4.2-beta as well.
