Just noticed it today too!
I will have to go back to check. I never noticed it when there but I didn't download anything yet today.
It's new. The ones saying 'donation' are done by miss Veronika. And I had a look, when uploading a new design you can only use 'free', 'donation' has not been added a choice yet. I think miss Veronika will make an announcement shortly.
It is definitely new - and some designs now say "donation".
I noticed that today for the first time, too!
I have only just noticed it, too
I have never noticed it until you pointed it out
