Opera heeft de eerste bètarelease van versie 11.60 van zijn gelijknamige webbrowser uitgebracht. Opera heeft  browsers voor alle belangrijke   computerplatforms en voor een groot aantal  mobiele besturingssystemen.   De browser biedt tabs, kan worden aangestuurd met  mouse gestures,   heeft een ingebakken downloadmanager en biedt  bescherming tegen   phishing en malware. Er kan met Opera niet alleen worden  gesurft, maar   ook gemaild; er is een ingebouwde bittorrentclient en er kan  worden   gechat via irc of met het door Opera zelf ontwikkelde sociale netwerk    Unite. De uitgebreide lijst met veranderingen sinds versie 11.52 kan hier worden gevonden. Dit zijn de belangrijkste verbeteringen die versie 11.60 met zich meebrengt:
Code nameOpera Presto 2.10 rendering engine
- Opera 11.60 beta uses "Tunny" as its code name.
 Opera Mail
- Opera 11.60 beta uses the latest version of the Opera Presto 2.10 rendering engine.
 The user interface for Opera Mail has been redesigned.
Featherweight address field with star menu
- 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 always 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 - New settings dialogs: The "View" dropdown menu with all its sub-menus has been replaced by an overlay dialog that can be reached by clicking the "wrench" button.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.
 - See: Mail goes two-lined and grouped
 The star menu in the address field allows you to quickly bookmark a page or to create a Speed Dial entry.

HTML5 Parser
