The beta drop of TFS SP1 is available, including bug fixes and new features like:

  • Support for custom controls in workitems
  • Remote HTTP access without the need for a VPN
  • Support for Office 2007
  • Support for moving the data warehouse to a separate server

However -- be aware that this is a beta drop, and the list of known problems is fairly nasty -- you should probably only install it on a pre-dogfood VPC image running on your oldest external drive during non-production hours. And wear gloves.
