ESLint v4.12.0 released

Highlights

New Rules

We’ve added 1 new rule with this release:

• implicit-arrow-linebreak

Autofixable Rules

We’ve added autofix capabilities to one rule: sort-vars. At present, it will only sort variables with no initial value or a literal initial value, in order to avoid potentially changing the order of function calls.

New Node.js APIs

We’ve added a new Node.js API:

• Linter.defineParser

This API is useful when you are working with an instance of Linter and need to define a custom parser at runtime.
