Flock made headlines by releasing a new version of its social web browser on the Chromium platform today, placing a great deal of emphasis on speed. However, Opera has also released a new version of its browser with a similar emphasis.

"Opera 10.60 beta is so fast, it will blow you away," says Opera Chief Development Officer, Christen Krogh. "Beyond the speed boost, the latest version of Opera improves on our robust HTML5 support and provides more options for quick and efficient Web search through your preferred search engines. By combining raw speed with intuitive and easy-to-use features, Opera places you among the fastest Internet users on the planet."

Opera says this version is over 50% faster than its predecessor on selected JavaScript tests. It also incorporates geolocation and WebM suppport for HTML5 video.

The geolocation feature detects your location and "maps you in the middle of the action" as the company puts it. They say this can give you more accurate search results in your area.

This version of Opera also introduces search suggestions for selected partners in the Speed Dial and search box. It works with Wikipedia search, for example.

The previous thumbnails for tabs have been replaced with icons, which Opera says speed up navigation. The Speed Dial, tab previews, and Opera menu button features all have new graphics.
