Mike Harsh: In the midst of all the work our team has been cranking on for Silverlight v1.1 (controls, databinding, layout, templates, styling and a package based app model, phew!), we've also been working with customers to address the top set of issues folks have hit with Silverlight v1.0.  Today we're happy to be releasing an update to address many of these issues.  The first Silverlight v1.0 service release is now live and includes the following improvements and fixes:

• Improved media performance and stability, especially for full-screen video. This includes improving A/V sync, which provides a better experience on lower-end machines.
• HTTP redirection now works for images and other media.
• Improved support for font managers & Mac Office 2008 fonts.
• Streaming video through proxied network connections only worked through port 80. Silverlight now respects the proxy port settings.
• Allowing access to all content embedded in .zip files with a non-.zip extension.
• Support for logging with Windows Media Services
• Loading XAML from a script tag will now work on all supported browsers.

The first bullet is the big ticket item.  It encompasses 4 sizable perf improvements that really make video in Silverlight hum.  This update will be rolled out to all users running Silverlight v1.0 via the auto-updater built into the plug-in.  If you’re impatient and want to get the update sooner, you can get it from the Silverlight installation page.
