New Features

• added a changelog
• added support for stripe.handleCardPayment and stripe.createPaymentMethod.
  These methods allow you to easily integrate Stripe's new Payment Intents API.
  Like createToken and createSource, these new methods will automatically
  find and use a corresponding Element when they are called.

    stripe.createPaymentMethod(
      paymentMethodType: string,
      paymentMethodDetails: Object
    ): Promise<{error?: Object, paymentIntent?: Object}>
  
    stripe.handleCardPayment(
      clientSecret: string,
      paymentMethodDetails: Object
    ): Promise<{error?: Object, paymentIntent?: Object}>

  For more information, please review the Stripe Docs:
  • stripe.createPaymentMethod
  • stripe.handleCardPayment
  • Payment Intents API
  • Payment Methods API

Breaking Changes:

• If you were already using handleCardPayment or createPaymentMethod with
  react-stripe-elements, you should upgrade your integration. These methods
  will now automatically find and use valid Elements.

  Old Way

  <CardElement
    ...
    onReady={this.handleReady}
  />
  
  handleReady = (element) => {
    this.setState({cardElement: element}) ;
  };
  
  let { paymentIntent, error } = await this.props.stripe.handleCardPayment(
    intent.client_secret, this.state.cardElement, {}
  );

  New Way

  <CardElement />
  
  let { paymentIntent, error } = await this.props.stripe.handleCardPayment(
    intent.client_secret, {}
  );

• Passing a beta flag to Stripe.js to use one of the PaymentIntents betas is not
  supported.

  Old Way

  // Old Way
  const stripe = window.Stripe(
    publicKey,
    {betas: ['payment_intent_beta_3']},
  );
  
  <StripeProvider stripe={stripe}>
    <YourCheckoutComponent>
  </StripeProvider>

  New Way

  <StripeProvider apiKey={publicKey}>
    <YourCheckoutComponent>
  </StripeProvider>

• PostalCodeElement has been removed. Users are suggested to build their own
  postal code input.
