[Plugin: Yet Another Related Posts Plugin] Version 3.4 loading same articles

Once I update to version 3.4 the related posts feature stop working fine, it was loading basically the same articles for every post on my blog. There is some kind of trouble in the way related matches are calculated on version 3.4+

For the moment I just downgrade to version 3.3.3 where related posts are loading fine.

Please could you fix this out? I really want to keep my plugin updated to its latest version.
