I was thinking SSDT, too.
Software updates in general seem to be driven more by marketing and perception than anything else, and don't EVEN get me started on version numbers. Just about the time you finish your procurement process, test a new version of something and are reasonably sure it won't break anything critical, you get to start all over again.
Personally, I prefer the approach of something like Slackware that gets released when it's darn good and ready, as opposed to the latest "Yowling Yak" followed near-instantaneously by "zig-zagging zebra" where the differences are so incremental you wonder: "Was a new version REALLY necessary?"
Just my $0.02 from over here in the cheap seats of the peanut gallery - please adjust for inflation and/or your local currency.
