XCode and Qt4.3 Release Build

[themolecule]

After upgrading from qt4.2 to qt4.3, when I build projects in XCode they are left in the Release folder, but they used to be in the same folder as the project. how do I set the destination directory of the build? I guess it's ok that it goes to the build/Release folder, but what causes this?

Also, if I do "qmake -macx" it always creates the xcodeproj in debug mode.
if I do "qmake -config release" then I get an xcodeproj that doesn't have _debug in the name, but the project settings are still left at "Debug" and I have to change it when I compile.

any ideas?
