The Commerce Server team has just announced the release of SP1 for Commerce Server 2007.

Here's the new features/enhancements they highlight:

• Support for Commerce Server 2007 Developer Edition and business user applications on Windows Vista
• Ability to create a Commerce Server 2007 Web Application Project in Visual Studio 2005 -- something that  it definitely needed!
• Performance enhancements
• Security enhancements
• Various fixes (here's a list of all the bugs fixed with SP1)

Note the fine print from the site: "Commerce Server 2007 SP1 includes updated binaries in English only. Each business user application that Commerce Server 2007 provides is available in English only. This does not affect your ability to develop a multilingual Commerce Server Web site.  Installing SP1 on non-English versions of Commerce Server 2007 is not supported."

I plan to update my virtual images with SP1, so I'll be sure and blog about the experience later tonight!
