Subject: [PATCH] Release 4.0.0

- The merchant-specific subdomain (environment_subdomain) is now required. Set it, or call the deprecated use_legacy_domain() to keep using the shared checkout.com hosts.
- An invalid subdomain now raises instead of being silently ignored.
- Add optional amount to VoidRequest to support partial voids.
- Add the ISV (SaaS seller) payout schedule fields balance_minimum, carry_forward_enabled and payment_instrument_id.
