Yeah yeah! Let's not make a "helipad" for version number, simply place it the same way the text is placed and it may look just fine.
On the other hand, this rectangle looks way better than the "mspaint" one, though the color, as you said, not really matches current design.
Another opinion on the source code version: Most of us look in the damn code all days, we don't want it to scare us even on a splash screen.
Btw when talking about previous splash screen inspirations, we really need to close this gap a little...
I believe you found better font than those previous splash screens had, but maybe the Code::Blocks label could be a little bit decorated, probably like on the first splash screen.
