This is the software publisher's description.

Try Adobe Fireworks to rapidly prototype websites, application interfaces, and other interactive designs. Create, edit, and optimize web graphics more accurately and faster than ever with the enhanced toolset. Demo your design live for your client, or e-mail an interactive PDF file. Leverage the new user interface and core functionality such as consistent text handling and the Adobe type engine. Output your Fireworks designs to the application platform of your choice: Adobe AIR, Flash, Flex, or HTML. In addition, export web standards–compliant, CSS-based layouts — complete with external style sheets — to Adobe Dreamweaver.

The Fireworks beta is an opportunity for web designers, web architects, and developers to participate in our pre-release program. This program provides you with early access to our next release so that you can kick the tires and ensure that it meets your needs. Download the next version of Fireworks now and send us your feedback. The Fireworks beta will expire soon after the next version of Fireworks is available for purchase.

This new CS4 version of Fireworks ships with a brand new user-interface, the ability to save CSS info with your images, the Adobe type engine and much more.

Important: This is a public beta, not a final release. Neither the quality nor the features are complete yet. We want to show you our direction and get your feedback so that we can incorporate it into future releases.

The download here will take you to the Adobe Labs page where you will need to sign in with your registration to obtain the latest download. You need to be a registered user of Adobe CS2 or CS3 to obtain a free beta trial CS4 serial code.
