404 on map files in version 7.0.1

Hi,

I upgraded from 7.0 to 7.01 and started to notice the following messages in the console window.  I reinstalled 7.0 and the messages were not displayed.

Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:63342/LearningRequireJs/js/lib/require.js.map:0
Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:63342/LearningRequireJs/js/main.js.map:0
Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:63342/LearningRequireJs/js/lib/jquery-2.0.3.js.map:0


I'm testing in chrome and I turned off map file in dev settings.

I am not using minified versions of require.js or jquery.

Anyone know why messages are showing up?

Thanx

John A.
