As Mike Dillamore mentioned in non-tech, the readme of the new Delphi 2006 hotfixes (btw, thanks, DevCo) says it applies to the following versions:
Product: Borland Developer Studio
Version: 2006
Update level: Update 2
Editions: Professional, Enterprise, Architect, Turbo
Languages: English, German, French, Japanese
Turbo is certainly something new to me... is there a new versions coming? Sounds like a low-end/personal version by the name, and quite a glorious name it is! Go, DevCo!
