Today it’s announced the new Acid3 compatibility tests for modern web browsers. The goal, defined by their press release, is:

The Acid3 Test is designed to test specifications for Web 2.0, and exposes potential flaws in implementations of the public ECMAScript 262 and W3C Document Object Model 2 standards.

Safari barely makes it halfway without errors, but with the history of webkit’s speedy updates, I look forward to seeing it validate years ahead of the oft delayed Internet Explorer.
