Release Notes

babel/babel-eslint

v10.0.0

Compare Source

v10.0.0

Small breaking change: add a peerDependency starting from the ESLint version that added a parser feature that we were monkeypatching before (and drop that code). If already using ESLint 5 shouldn't be any different.

• Bugfix for TypeAlias: #​584

/* @​flow */
type Node<T> = { head: T; tail: Node<T> }

// or 

type File = {chunks: Array<Chunk>}
type Chunk = {file: File}

• Update to test against ESLint 5, add a peerDependency: #​689
• Drop monkeypatching behavior: #​690

This isn't a breaking change for us, since we already have a peerDep on a newer ESLint than the range they've added.
