Opera 10.5 has leaked to the web ahead of its December 22nd release. Along with a new interface, the browser offers better compatibility with Windows 7, private browsing, and a new rendering engine that should provide for faster web browsing.
A screen shot of the updated browser is posted below and provides a similar look to Google"s Chrome. Opera has stated that the screen shots posted below are legitimate but are from an older build according to techie-buzz.com.
The leaked browser, while available on the web right now, is most likely far less stable than the version that will be released tomorrow. Expect to see a slightly tweaked interface with the newer version and you will be able to try out Carakan, their new ECMAScript/javascript engine, which is not present in the leaked version.
