Notifications and like mentions

Hi there,

Since I've upgraded to 4.1 from 3.xx, I've noticed that the notifications doesn't tell us anymore who did what. For example, if someone like a comment i've made, i'll receive a notification saying "someone" like your comment in ....

Same thing for actual likes. We cannot see who like what for example.

Is there a way to set it up so that we have access to those informations?

Thanks guys
