// @changelog    新增：\n1.新增WebP、HEIF等格式自动转化为PNG以及压缩链路。请注意HEIF图片无法预览。\n2.添加基于获取版块页首页信息拉起发串信息的回退机制，用于“测试”版块发串信息的获取；同时，“测试”版块默认发串模式。\n\n优化：\n1.优化“浏览历史/发言历史/我的订阅”以及拓展坞启动的速度。\n2.优化了图片懒加载并发队列与动态预加载机制，现在可以更快加载滚动方向上的图像原图。\n3.阅图模式按钮与图片显示模式状态同步。\n\n修复：\n1.修复了部分图片错误进入压缩循环且无法提交的问题。\n2.修复在发送前二次确认窗口中使用鼠标点击的饼干没有被选择并作用，而实际使用列表最后一个饼干发送的问题。\n3.修复拓展引用弹窗在打开多层后，较早的层级无法拖拽移动的问题。\n
