ESLint v7.30.0 released

Highlights

You can now set "ecmaVersion" to "latest" under parserOptions in your configuration file:

{
    "parserOptions": {
        "ecmaVersion": "latest"
    }
}

"ecmaVersion": "latest" always enables the latest supported ECMAScript version in ESLint’s default parser.

Please note that this feature applies only if you are using the default parser. If you’re using a custom parser, refer to the parser’s documentation for the list of available options.
