ESLint v7.30.0 released

We just pushed ESLint v7.30.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.

Highlights

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.
