I think you are definitely right, I realized another problem with it about ten minutes ago.

Previously the plugin removed article and category ids, and also parent categories from the url. Now it doesn't remove the parent categories (though you won't see the problem on my site because i've gone through and moved the affected categories so they have no parent).

Do you have any recommendations for an SEF url extension that doesn't have this problem in 3.7? I know its new but I'm sure you are more plugged into the scene than I.
