RC7 vs RC6 Y Direction

In troubleshooting something else, I flashed with the RC7 version of the firmware. I previously had the preloaded RC6. After the flash, my Y axis is inverted. I cut a simple word using the SD card and it needs a mirror to read it. I tried to control it with Repetier and it also ran backwards.

Is there a setting I missed in Ramps? Did something change between the versions related to this?

Power down and flip the y axis plug.
