I don't understand what you were trying to say with reference to SplendidConfigure. Please rephrase.
Is SplendidConfigure the tool that does all the database changes when you upgrade?
How do you get database changes for interim stuff that we get down from SGV?
For a small additional fee, we offer our Professional customers access to the SQL code stream. Open-source customers just have to wait until the next published release.
The advantage to provding access to the ASP.NET source code is that the open-source customers can obtain some fixes. We believe that some is better than none.
