Release Notes

babel/babel-eslint

v10.0.1

Compare Source

v10.0.1

• Reverting #​584

The TypeAlias "conversion" to a function has issues. Sounds like we need to rethink the change, most likely we can just actually change the scoping rather than hardcode an AST change.

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

v9.0.0

v9.0.0

We've released v7: https://twitter.com/left_pad/status/1034204330352500736, so this just updates babel-eslint to use those versions internally. That in itself doesn't break anything but:

• Babel now supports the new decorators proposal by default, so we need to switch between the new and the old proposal. This is a breaking change.

To enable the legacy decorators proposal users should add a specific parser option:

{
  parserOptions: {
    ecmaFeatures: {
      legacyDecorators: true
    }
  }
}

• Babel removed the support for Node 4 , so I propagated that here.
