与以往不同的一点是，Opera 11.60 正式版没有选择最后发布的 RC 版作为正式版，正式版 build 版本号为 1185。Opera 11.60 的重要更新包括 HTML5 Parser、M2、更多 HTML5/ECMAScript 5.1/CSS3/CSS4 等标准支持，号称解决了五分之一的兼容性问题。但是对于不用 M2 的用户来说，11.60 的可见更新只有地址栏那个小星星了。

Opera Mail
The user interface for Opera Mail has been redesigned.

Two-lined message list: Opera Mail will now default to “list on the left, message on the right”, with the newest message on top, and showing message threads.

Mail grouping: Opera will automatically group messages by date. You can also group them by unread status, by pinned status, or not at all.

Cleaned up look: The mail toolbars are simplified, and icons have been redesigned.

New settings dialogs: The “View” dropdown menu with all its sub-menus has been replaced by an overlay dialog that can be reached by clicking the “wrench” button.

Pinning: You can now “pin” messages with one click in the message list or in the message headers, to mark a message for attention. This pinning is mapped to the IMAP Flagged feature, so it corresponds to “starring” and “flagging” in other IMAP clients, and with Gmail’s starred messages.
