Richard Collins wrote to say that SQL Compare v7 is being released this month, and will include SQL Server 2008 compatibility as well as being able to compare against backups.
Regarding my comments about version control for database schemas, he said the following:
“I just thought I might mention that v.6 of SQL Compare also includes the ability to compare with a folder of sql scripts under source control (optionally via an add-in called SQL Changeset) which
I believe will help with your problem of updating from multiple possible versions.”
Stephen Chambers also dropped me a line to mention that they’re working on ANTS Profiler v4. Pre-release builds are free and can be downloaded via their support forum.
