For those SCM fans out there, exciting news: Microsoft just released a CTP of SCMv2. The most important new feature is the ability to import a GPO backup and associate that imported GPO against a product. Another new feature is the ability to use an existing installation of SQL Server (2005 or later) instead of the SQL Express version that was forced until now.
While the current CTP is not yet feature complete, Microsoft expects a feature complete version for a April/May beta release.
