Did the Forum get a new Look?

​Before, there was a "like" button.
Long time ago, there was also "unlike" button

And now, what it is ?
You add a "grinning face" because the post was very funny, a "smiling face with hearts" because the avatar is pretty, and a "smiling face with sunglasses" because your computer is in front of the window and the weather is sunny ?

In addition, it seems that you can't know who add what, and you can add your own opinion...

So a user's manual would be welcome
