The browser, which has been given the codename Barracuda, features the same streamlined design as Opera's previous browsers, but also benefits from a new-look Speed Dial, which Opera says makes it easier and faster to access your favourite sites.
The number of Speed Dials a user can assign is also now unlimited, and the features comes with new layout choices, and an improved zoom slider.
Furthermore, Opera 11.10 will download Flash automatically and install it in the background when you visit a page that requires the plugin.
The browser also features a number of 'under the hood' improvements including a new browser core, that makes Barracuda the fastest version of Opera so-far, as well as adding support for CSS3's multi-column layouts and gradients, the Web Open Font Format (WOFF) and Google's WebP image protocol.
"Barracuda is our first release in the new year and shows off some of our freshest ideas to make your browsing easier," said Jan Standal, VP of desktop products at Opera.
"If you are already an Opera fan, you will appreciate the polish we added to Speed Dial, a favourite feature for many millions of people who use Opera. If you've never tried Opera, maybe Speed Dial will become your favourite feature. And the best part? It only gets better from here."
The beta version Opera 11.10 is available to download from Opera's dedicated web page for Windows, Mac and Linux PCs.
