yes, I know but what I don't understand is how is the 1.0 contains something updated if there is only ancient winavr stuff inside. Maybe I am confused with the relation with avrdude-winavr, I got the last package of winavr and tweaked the IDE to make it work. I can't find a newer version and for me winavr includes avrdude. So I left the previous files since in the last official package the 'tools' files are 2008-2009
