Thank you .
I ran a test.
here are two NC.drl files. You can see what 10.0.1 added to the NC file. Some reference notes. they are supposed to be ignored by the viewer but they are not because i uploaded this file once with the additional info and again with the info removed. The manually modified file rendered in their gerber viewer.
These are from the same project that were compiled under version 10.0 in september and then under 10.0.1 in january
