For bug reports. I currently group bug incidents that occur on the same file in the same line into one bug report since they are most likely the same. I do not however take into account phpma version. should I only group bug incidents from the same file and line if they share a phpma version?. I looked at [0]. I am not sure how they group bug incidents but every report has a single kernel version. I think I should do the same and rely on manual interference by developers to mark the bug reports in different versions as the same.
