ESLint v8.x end-of-life is 2024-10-05 and will not be maintained after that. Upgrade or consider long-term support options

ESLint v4.7.0 released

We just pushed ESLint v4.7.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.

Highlights

  • newline-per-chained-call supports autofix.
  • Processor plugins can now autofix code. To support autofix in processor plugins, developers can signal support by setting supportsAutofix: true and update the postprocess method to transform fix ranges in reported problems. This is explained fully in the Processors documentation.
