After releasing a beta in late November, Norwegian software developer Opera Software has finally introduced version 11 of its flagship Web browser to the general public.
Opera 11 comes with a number of new features; among the most notable is “tab stacking,” which allows users to combine multiple tabs into a group in order to reduce clutter. The new browser also introduces extensions, which all its major competitors have offered for some time (Safari being the most recent to introduce them, when version 5 was released in June).
Other additions include increased support for HTML5 and geolocation, enhancements to the browser’s security systems, and better development tools, designed to bring Opera on par with recent advancements introduced in other desktop and mobile browsers.
Despite commanding a relatively small portion of the overall browser market—recent statistics give it a market share of between about 2 and 3 percent—Opera has carved a profitable niche in the consumer market, where it is a popular choice for mobile and console manufacturers, as well as set-top TV boxes. It is, for example, the only browser available on Nintendo's Wii and DS devices.
Opera 11 is available as a free download directly from the Opera website. According to technical information collected from the binary package the company makes available for download, it requires an Intel-based Mac running OS X 10.4 or higher.
