There are many exciting new features in this release. For example, Expression Web allows you to design PHP documents in addition to ASP.NET 3.5, opening the door for a new range of designers to create their standards-based designs using Microsoft tools. Expression Blend has an improved interface that speeds up your workflow and facilitates navigating your documents more quickly with the new breadcrumb toolbar. Expression Design includes an advanced slicing feature that helps you target individual slices as separate formats, including Silverlight canvas, WPF canvas, WPF resource dictionary, HTML comp, XAML, PSD, and PDF. Expression Media makes digital asset management easy by allowing you to import more than 100 different media formats using drag-and-drop, including digital camera RAW files, then share the resulting catalogue with fellow team members. Finally, Expression Encoder has higher quality and faster encoding for Silverlight and the ability to perform simple video edits
To enable designers to begin exploring the power of Silverlight 2, today we also released Expression Blend 2.5 March 2008 Preview, a pre-release of the next version of Blend (post Expression Studio 2) that will eventually ship alongside Silverlight 2. As Silverlight and other platform technologies continue to advance, we will regularly release refreshes of our developer and designer tooling.
