Opera has released the first alpha version of Opera 10, which introduces a new version of the Presto engine, according to a post on the Opera Desktop Team blog. The new version of Presto, 2.2, receives a perfect score in the Acid3 test, a test of compliance with web standards. The only other engine that has reached that score is Webkit, used in Safari and Chrome. The new engine also adds support for Web Fonts, a feature of CSS 3 that specifies where to download a font if the computer of the website’s visitor does not contain it. Opera claims that Opera 10 is 30 percent faster “on the real web.”
