Photoshop: Was there a change in the way DCS2 files and spot/alpha channels are saved?

Ho notato che nell'ultima versione di Photoshop CS5 salvando dei file nel formato DCS2, oltre ai canali di tinta piatta, vengono salvati anche tutti i canali alfa presenti nel file stesso, cosa che invece non succedeva nelle versioni precedenti, chiedevo se fosse un difetto del programma, oppure se si tratta di cosa voluta, anche se apparentemente non ne vedo il motivo.
Grazie

Google Translation:

I noticed that the latest version of Photoshop CS5 DCS2 saving files in the format, as well as spot color channels, are also saved all the alpha channels in the file itself, something that did not happen earlier, wondering if it was a defect program, or if it is desired thing, though apparently I can not see why.

I don't believe that has changed in many, many years.

Where are you seeing the changes? Are you opening the files in another application?

If a PSD file, containing a spot color, and a number of alpha channels, DCS2 save a file, then reopen as philias in CS5, you will see all the alpha channels active, the same file layout with In Design, you then creates problems when printing.

I installed Windows CS5, and saving files DCS2, occurs regularly without alpha channels, but the only spot channel, evidently, is a problem for new versions of the Apple platform.
