Bugsnag local

Currently bugsnag reports for both local and production. I don't need it to report for my local development because I can see the error my self.

I am using https://github.com/bugsnag/bugsnag-laravel

In the doc it says do something like this in the config file:

return array(
    'api_key' => env('BUGSNAG_API_KEY'),
    'notify_release_stages' => ['production', 'staging']
);

But it is not clear on how to set it up to not report local. The doc is a little unclear because bugsnag reports on both local and production.
