ESLint v9.1.0 released

Highlights

This is the first minor release of ESLint following the major release of ESLint v9.0.0 earlier this month.

• Intl is now recognized as a built-in global unless languageOptions.ecmaVersion is set to 3 or 5.
• The no-constant-condition rule no longer reports while (true) loops as problems by default.
• A configuration that contains a non-global ignores pattern list will no longer cause incorrect results when the --no-ignore CLI flag is used, or when the ESLint constructor option ignore is set to false.
