Opera 12.00 snapshot 1317:提高 CSS 单位精度

此 Opera Next 新版的 Presto 内核版本已升至 2.10.269。

此版本采用一种统一的方法处理布局所使用的定点数值(长度、字体尺寸)。以往采用的限制多又不精确的旧方法——把百分比和 em 值圆整为最接近的整数,将被更优良的新方法取代。

更新日志除此之外似乎也相当充实的样子。

已知问题

  • DSK-358417 升级导致扩展的设置和本地储存(localstorage)丢失
    —变通以克服的办法是卸载扩展,重启 Opera 再重装扩展(我不知道这算什么克服办法,只好直译。“卸载扩展”也没说清楚是升级 Opera 12 前卸载还是升级后卸载,大家小心为妙,升级前最好备份。扩展数据存放在 profile 里面的 widgets 文件夹当中)
  • 载入页面非常快(Very fast page loading) ?_?
  • 使用地址栏小星星菜单添加书签可能导致假死或崩溃
这是一个开发版,不推荐普通用户使用,仅供测试。此版本存在着很多已知问题,可能会造成崩溃或者数据丢失,甚至无法正常使用。请勿覆盖之前的版本,并在备份数据后安装使用。

《Opera 12.00 snapshot 1317:提高 CSS 单位精度》有19个想法

  1. 这个版本的亮点本来应该是摄像头支持啊~不过看内核版本都有拖曳和动画至支持了 不知道什么时候出来

  2. 这样的更新速度才爽。话说Opera在NWC推出了一个叫Opera Payment Exchange(OPX)的服务

  3. 我去 本来 扩展信息是完整的 ,升级这版 全部清零 ,特别是noads 幸好哥前阵子备份了…要不就费劲了 还得一个网站一个网站地撸
