+### API: Prettier now works in Atom again ([#6129] by [@duailibe])
+
+Atom has a security feature where code containing `eval` is not allowed to be run. One of Prettier's dependencies uses `eval` to prevent bundlers from including debug code. We've now made sure that this `eval` does not end up in the code we ship to npm, making Prettier play nice with Atom again.
