In v41.0.0, stripe-dotnet is now pinned to Stripe API version 2023-08-16. When upgrading, please read the API upgrade guide and review each item to determine if changes are necessary for your integration to become compatible with 2023-08-16.

Of particular note: Stripe has changed the defaults that apply when you use a PaymentIntent or SetupIntent without specifying the payment_method_types parameter. Read more about this change here, and carefully review any of your code that calls PaymentIntent or SetupIntent APIs to see if you are affected.
