I have an application that is using a GFTT detector and after I have done an OpenCV update form 2.4.9 to 2.4.11, the behaviour is changed. There are more features after matching. So I am wondering if there is a bug fixed or some improvement in feature detection or descriptor matching, or maybe in Otsu threshold?

This is not the only thing you can check but you can diff the tags on github . I know it's rather big, but you can also do this for specific files. You can also search the issues here or the pull requests here.

I have changed the version of OpenCV, but I have not managed to see any differences in the results... I have searched for differences in versions of my code, but I have not found any that may influence the results... I know it is strange, but is there a possibility that OpenCV merge the fix of a bug in all the tags?

Well tags are fixed markers (okay, not really fixed, but we can assume they are) at a certain commit (point in time), so no, if this was a bug was in 2.4.9 it will always be there.

Most likely it is a minor change in your code, or you were not really working on 2.4.9 before...

Maybe it was a result from a much older version, and since then I have changed the code, and the person who remarked it, does not remember exactly... I close the question. Thanks you all
