 - Adds `Billing.retrieve_payment_methods()`, `Billing.fund_wallet()`, and `Billing.delete_payment_method()` functions
+- Captures OS information in the user-agent header for easier debugging
+- Update functions now use `patch` instead of `put` under the hood to better match API behavior and documentation. The behavior of these functions should remain the same
