Stripe stripe-php library outdated?

Hello there!

I’m trying to implement the relatively new Stripe Tax system. In the process I realized that these kinds of attributes are not supported by the current library version (7.36.1 compared to latest 7.87.0).

$subscription_params['automatic_tax'] = array(

      'enabled' => true,


I get:

Received unknown parameter: automatic_tax (Stripe Tax is an invite-only feature. Please request access at

At first I thought it was a Stripe API/configuration issue, but using the latest stripe/stripe-php library + latest Stripe API version ( 2020-08-27) outside the addon works just fine with the exact same params.
