The good just got better with the release of the Opera 10 alpha made available earlier today to showcase the new Presto 2.2 rendering engine. The company claims the new rendering engine is up to 30 percent faster than Presto 2.1, which provides the foundation for Opera 9.5, while also touting full web standard compliancy.

"Opera has fine-tuned its standards support and, as a result, Opera 10 alpha achieves an Acid3 100/100 Test score," Opera Software wrote in a press release. "This version also provides Web developers with a whole range of new technologies for building better Web sites."

By comparison, Firefox 3.0.4 scores 71/100 on the Acid3 Test, with Firefox 3.1 beta1 and Google Chrome 0.4 scoring 89/100 and 79/100 respectively, according to Cnet.

Several updates are also included in the new Opera browser, including support for the latest HTML and CSS standards, opacity modifications through RGB and HSLA for setting the opacity of any web page element, inline spell-checking, an auto-update feature, and other goodies.
