Opera has always been the leader in innovating web-browser technologies and once again the Opera team has came-up with some promising stuff with public release of Opera 10.5 Pre-Alpha, the major new features worth mentioning here would be the all new JavaScript rendering engine Carakan which is touted to be 7x faster in benchmarks then it's predecessor Futhark used in current stable release of Opera 10.10, new Presto 2.5 engine with support for CSS3 transitions and transforms with more HTML5 features, new hardware accelerated VEGA graphics library and support for private tab (no need to open a window) apart from the new address-bar and other GUI enhancements.

Opera Labs is doing some extra-ordinary research in terms of new web-browser features and after introducing Opera Turbo they seem to have gone too far with experimenting introducing face gestures in the latest snapshot builds of Opera 10, the concept of controlling your web-browser with facial expressions sounds pretty cool but after seeing the video demo with man making funny faces to control the web-browser, I decided to stick with keyboard and mouse combination for a while, jokes apart the technology seems promising considering the evolution of touch devices where such functionality can be handy, I am very much sure that Opera will tweak this facial-gesture technology further to create something useful.

Opera is all set to become the worlds fastest web-browser with its server-side acceleration technology to be included in upcoming Opera 10 release, the Opera team released the first public alpha of Opera Turbo demonstrating the compression technology meant for users on low-bandwidth connections, working similar to the man-in-the-middle proxy compression system used by commercial software's like ONSPEED Web Accelerator, Opera Turbo compresses network traffic providing significant improvements in browsing speeds consuming less data saving bandwidth bills.
