During the installation I told it to install everything.
After installation I tried to take a screenshot for another bug report. A very
thorough search of all the menu items revealed nothing that seemed like it was a
screenshot tool. In desparation, I hit printscreen. Well, it worked, but it
was not obvious how to get there.
I don't think there's any reasonable place to put this menu item, that's why
it's gone. It's really not essential functionality for most people so I think
having it only in an app such as Gimp and on the PrintScreen key is appropriate.
