The release of XenDesktop 4 FP1 was timed with the release of XenApp 6, Citrix's Terminal Services-based product line. XenApp 6 was a complete rewrite, addressing several major architectural issues that many users have wanted for years.
The first is that XenDesktop is now fully (and tightly) integrated with Microsoft's App-V application virtualization solution. In XenDesktop 4 FP1, it's just as easy to publish and deliver App-V apps as it is Citrix XenApp apps. This is great for end users who doubt that Citrix's own app streaming will ever be as good as Microsoft's. Now it doesn't matter.
Another new feature is that centrally-managed user profiles are streamed into desktops on demand. Previous versions of XenDesktop loaded the entire profile during the logon process, making logons slow for power users.
Feature Pack 1 adds a lot of support for graphics capabilities, including 32-bit color support, Windows 7 Aero support, and a special "lossless" quality mode for things like medical imaging apps, where you don't want to miss a brain tumor because of a compression algorithm.
Citrix also added support for x64 virtual machines -- both Windows XP and Windows 7. Many customers have been slow to move to x64 for their desktop operating systems, and Windows x64 certainly consumes more memory than the 32-bit variants, but x64 offers better performance than 32-bit, even for virtual desktops. And thanks to Feature Pack 1, we now have the chance to find out.
In addition, Feature Pack 1 adds several little features, like better client USB device support, new support for Microsoft Office Communication Server (OCS) and Voice over Internet Protocol.
Like all feature packs from Citrix, XenDesktop 4 Feature Pack 1 is free for customers whose subscription advantage programs are up to date. Although it's not groundbreaking, FP1 has a bevy of new features and enhancements that move XenDesktop that much closer to being able to support every corporate desktop use case.
