11.5x 已经结束，12.00 小露头角，现在又来了 11.60，代号金枪鱼（Tunny），期待看到新成员的上佳表现。在 Opera 12 中已经包含了许多重要的核心更新，其中对 Web 标准支持的很大改进，对网站兼容性有积极的影响。然而其他的功能，包括硬件加速仍然需要大量的开发工作。我们对于硬件加速的期望非常高，认为最重要的是要做得更好而不是更快。因此，我们决定放出没有硬件加速的分支 11.60，让用户可以更早的享受到其他稳定的新特性。
Opera 11.60 和 12.00 将并行开发。建议分别安装而不是覆盖。

重要更新

Presto 引擎更新至 2.10.228

全新的 HTML5 Parser，重大的不可见更新，号称可解决五分之一的兼容性问题

新版 Carakan 引擎，优化内存占用

完整的 ECMAScript 5.1 支持

CSS3 径向渐变支持

HTML5 custom scheme 以及 content handlers 支持（新特性哦，12.00 可是没的哦）

新的羽量级地址栏及星号书签按钮

硬件加速及新的皮肤被禁用，未来将在 12.00 中开启

除了上面的这些，试用发现快速拨号的行为已经恢复正常。

已知问题有：

不支持从 12.00 上自动更新

Mac 下 Flash Player 11 会造成崩溃，建议禁用之
