ESLint v8.9.0 released

We just pushed ESLint v8.9.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.

Highlights

  • New es2022 environment has been added. When enabled, it adds all ECMAScript 2022 globals (which are currently the same as ECMAScript 2021 globals) and automatically sets the ecmaVersion parser option to 13. Previously, we used to add new ES environments only if they contain new globals compared to previous years. New es2016, es2018, and es2019 environments have also been added to fill in the gaps between years.
  • eslint-scope has been updated to ignore "use strict" directives in ES3 code.
  • eslint-visitor-keys package now contains built-in TypeScript declarations.
