Barracuda, Swordfish, and Wahoo are the familiar attractive code names of the Norwegian browser Opera. The browser version is actually Opera 11.10, Opera 11.50 and Opera 12 respectively. Among the list the first two are stable versions and the third one is the first development snapshot / alpha.
A snapshot is a glimpse into the next major release of Opera for Desktop. They contain experimental and incomplete implementations of new features, as well as work-in-progress on bug fixes.
Wahoo aka Opera 12 released in last July and before going to the next major release of it, the Opera team pushed another version of Opera called Tunny aka Opera 11.60. Little bit confusing? I will make it clear. Tunny comes between Swordfish and Wahoo. Now the order is Barracuda, Swordfish, Tunny and Wahoo.
New Features Included in Opera 11.60
- A new HTML5 parser (Ragnarök)
- A new version of Carakan—our ECMAScript (JavaScript) engine—with improved memory management on complex web applications
- Full ECMAScript 5.1 support
- CSS3 radial gradients
- Support for HTML5 custom scheme and content handlers (new in this build)
- New featherweight address field with bookmark star menu
- Presto (Opera’s rendering engine) upgrade from 2.9.220 to 2.10.228
Before install please take note that this not an Opera Next Build. That means it will upgrade your Stable Opera. To avoid this you need to follow the standalone installation method as detailed below.
- Start the installer and click on “Options”
- Change “Install path” to a location you have write access to (do not use “Program Files”) and make a suitably named new folder e.g. “Opera-11.6″
- Change “Install for” to “Stand-alone installation (USB)”
