What version is the Doom Collector's Edition?

[Kenny McCormick]

What version is the Doom Collector's Edition running/will I ever have to worry about upgrading, and no I don't mean the source ports, I mean the base files, like my IWADs.

DCE IWAD's are all 1.9

No, you won't ever have to worry about upgrading iwads.
