Features:

Live View
Design your web pages under real-world browser conditions with the new Live View in Adobe® Dreamweaver® CS4 — while still retaining direct access to the code. Changes to the code are instantly reflected in the rendered display.

Code hinting for Ajax and JavaScript frameworks
Write JavaScript more efficiently with improved support for JavaScript core objects and primitive data types. Put the extended coding functionality of Dreamweaver CS4 to work by incorporating popular JavaScript frameworks, including jQuery, Prototype, and Spry.

New user interface
Work faster and smarter across Adobe Creative Suite® 4 components with a shared user interface design. Toggle quickly from one work environment to the next with the workspace switcher.

Related Files and Code Navigator
Click any included file shown in the Related Files bar to see both its source in Code view and the parent page in Design view. The new Code Navigator feature shows you the CSS source code that affects your current selection and allows you to access it quickly.

HTML data sets
Integrate the power of dynamic data into your web pages without the learning curve of mastering databases or XML coding. Spry Data Sets recognize content in a simple HTML table as an interactive data source.

Adobe InContext Editing (Free preview)
Design your pages in Dreamweaver so end users can edit their web pages without help from you or additional software using the Adobe InContext Editing online service. As a Dreamweaver designer, you can limit changes to specific pages, distinct regions, and even custom formatting options.

Adobe Photoshop Smart Objects
Insert any Adobe Photoshop® PSD document in Dreamweaver to create an image Smart Object tightly linked to the source file. Make changes to the source image, and update your image in Dreamweaver without opening Photoshop.

CSS best practices
Implement CSS best practices without writing code. Create new CSS rules in the Properties panel, and get clear, simple explanations of where each property fits in the cascade of styles.
