Minecraft 1.14 still considered "snapshot"

Even though Minecraft 1.14 is a full release, saved worlds from prior versions still remind you:

"Don't forget to backup this world before you load it in this snapshot."

 

To recreate:

Open up Minecraft

Press play

Hover mouse over world last played in previous update

Message will appear

 

No, I am not playing on a snapshot, see images below
