> To date, CORS network errors have been shown as warnings, making them too easy to overlook when resources could not load. Now they are correctly reported as errors, not warnings, to give them the visibility they deserve.

I know this is a small improvement (s/warning/error), but like it nevertheless. What I would _LOVE_ however is that CORS errors would be displayed where it would make sense - in the Network tab. When I'm debugging connections I am looking there, not in Console.
