Yesterday I installed the RAD Studio 2007, over my existing Delphi 2007 for Win32 (Update 3) installation.
Installation gave no problem, except for a few packages that needed to be recompiled. Although I don't need RAD Studio 2007 anymore (since it does not have a winform designer), I was curious about the new ECO IV for VCL.NET.
Well it looks that ECO is only available in the Architect edition, which it was in the BDS2005 erra, as I recall. In BDS2006 it was introduced in all the SKU's at different levels.
Anyway I have mixed feelings for this release, at one hand it fast, stable (iow it rocks!), but on the other hand it misses important features compared to BDS2006.
Go Delphi for Win32!
