No more AutoCAD Educational plot stamps or warnings
Beginning with AutoCAD 2014 SP1 (and presumably in future later versions), drawings "infected" with the educational plot stamp will no longer plot the EDU stamp and you will not be warned about the stamp when opening the drawing.
This was confirmed by Autodesk employee Shawn Niles in this thread at the Autodesk forums. Note that "infected" drawings will still contain the EDU indicator, and this can and will propagate to other drawings. Shawn says that the "the current plan is that the 2015 version will have the ability to remove the stamp altogether". Unfortunately, the link in that message is no longer valid.
Note that the SP1 readme file makes no mention of this change. Not sure if that omission was done on purpose or not. We are a little confused as to why this is being done. Isn't this going to allow anyone to download and use the free EDU version just like it was a paid commercial version? I guess we'll have to wait and see what the plan is.
