I completely agree and I already said it before, but somehow all others 
thought it would be better if e.g. libkdeui from KDE 2.0 (at that time) and 
from KDE 2.1 and 2.2 all have the same version number 3.0.0 :-/
Every other project which produces libraries increases their version numbers 
for new versions with new features or bugfixes (well, that's why they are 
called version numbers ;-)
We only increase the main number if it becomes BIC.

I don't think that it is a good thing that I can have three libraries named 
libkdeui.3.0.0, libkdeui.3.0.0 and libkdeui.3.0.0 and that I can't simply 
exchange one with the other, since e.g. 3.0.0 from 2.0 doesn't provide all 
the features 3.0.0 from 2.2 provides.

Another advantage of the version numbers would be that this would make it 
much easier to find out which version of KDE is installed, especially in the 
case if something is messed up and KDE or X don't even start.

I'd say better do something late then never.

Ok, enough.
