New Contacts Preview Updates Icon

It seems some time over the past few days, the Gmail team decided to update the New Contact button on the New Contacts Preview. Previously the FAB (Floating Action Button) was a big blue circle with a white plus sign in it. At some point recently, the team updated this to a big red circle  with a whit plus and the top half of a person to indicate new contact.  See below for what the new button looks like.

I suspect this was done to alleviate the many inquiries on the product forum regarding how to add a new contact in the contacts preview program.
