There are going to be 3 new whips in 1.4.5
(lemmy.ml)
You can see on the bottom row that there are three new whips. The one on the left looks like it going to be crafted with the stardust fragments.
u/daniersy890 reversed the math the game uses to draw transparent objects, so we can see the original sprites. The two other whips seem to be a duke fishron and a moon lord whip.
