There has still been no official announcement.
But Admins have replaced the "Thank & Like" button with the thumbs up.
You can now only "Thank" the original poster (1st post)
You can "Thumb Up or Down" every post after.
If you wish to give somebody rep... you need to start using the rep button.

Don't worry about it.
