Three years after Acid2 Browser Test the Acid3 Browser Test was released (03/03/2008).

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. Collectively known as DOM Scripting, it is these technologies that enable advanced page interactivity and power many advanced web applications such as web-based email and online office applications.
