The Python license says:
"In the event Licensee prepares a derivative work that is based on or 
incorporates Python 3.0c1 or any part thereof, and wants to make the 
derivative work available to others as provided herein, then Licensee 
hereby agrees to include in any such work a brief summary of the changes 
made to Python 3.0c1."

Other licenses specify that derivatives use a different name or even 
distribute changes as a patch for the unchanged original.
