The latest browser betas from Opera have been released, emphasizing speed improvements and better HTML5 compliance. Opera 10.60 for Windows, Mac, and Linux gives fans of the alterna-browser a bucketload of HTML5-related improvements, along with the claim that the company has made the browser 50 percent faster than the previous version.

It's not clear from the press release whether this meant that the Opera 10.60 beta 1 should be 50 percent faster than than the last Opera 10.60 alpha, or 50 percent faster than the current stable Opera, version 10.53. Benchmark testing will be added later in the day.
