Description

In OpenCV 2.4 

calcOpticalFlowPyrLK(opticalFlowTrackerImgOldGrayMat, opticalFlowTrackerImgGrayMat,
    LKpoints[0], LKpoints[1], status, err, winSize, 3, termcrit, 0, LKSHIFT_TRACKER_ERROR_RATE );

In OpenCV 2.3.1

calcOpticalFlowPyrLK(opticalFlowTrackerImgOldGrayMat, opticalFlowTrackerImgGrayMat, 
    LKpoints[0], LKpoints[1], status, err, winSize, 3, termcrit, 0.5, 0, LKSHIFT_TRACKER_ERROR_RATE);

Please add compatibility wrapper to prevent passing of incorrect params in older program code.

Cheers,
J

sorry, it was indeed a dangerous change, but I do not see an easy way to roll it back. Introducing a new function will not help either, because in most cases compiler won't be able to figure out which function you intend to use => a lot of new code will break too.
