I uploaded a new version of my app in iTunes connect and I do not want and/or need it - how do I get rid of it?

You cannot delete a new version you have created from iTunesConnect before you have uploaded a binary. You can only delete full apps - before or after review.
Apple give a fairly full description of what is going on here without saying explicitly that you cannot delete versions. They do say you cannot remove a platform once created - and they seem to work like versions.
I suppose they never imagined people would create a new version by mistake or as an exercise - but we do!
The only reason I can think of is as a safety measure so that you cannot strand people who have bought your app for a platform that you then remove. I am guessing versions work like platforms in the background and so Apple cannot give us the functionality for one and not the other.
