出现无法播放情况先关闭自动修复
2013-12-14修复B站播放器无法在火狐魔镜弹窗播放
2014-01-23替换优酷、爱奇艺、搜狐为B站播放器
2014-03-28增加下载视频按钮
2014-05-10收益于自己的B站追番计划(http://v.myacg.ga或者http://weiyun.jd-app.com)，代码逻辑重构(不再区分视频源再解析视频)，并重写UI
2014-05-10受诸多基佬要求，增加除首页外其他分类页面的弹窗播放(初衷是为了弹窗乐视源)
2014-05-11还是基佬要求，增加弹窗播放器分P效果，增加弹幕下载功能，在吧友大神田生的建议下，正则表达式加强匹配
2014-05-13增加搜索页面的弹窗播放，并且支持多P和显示当前P，增加模糊画质下载按钮
2014-05-14增加首页弹窗播放，基本实现全站可弹窗（首页新番专题列表除外等）
2014-05-25感谢吧友lzgptdgj提供BUG，在小型播放器下，屏蔽规则会无效的问题，已经修复
