## Enhancements

* Added enhanced sandbox support for testing embedded components. Now, when using an embedded component in the sandbox environment, you must add `data-test` as a configuration variable to the script tag. For example:\
  `<script src="https://embedded-component-sandbox.payabli.com/component.js" data-test></script>`. This configuration variable shouldn't be used with the production library.
* Added support for alphanumeric account holder and cardholder names in embedded components.
* Added support for different ZIP code formats.

## Bug fixes

* Fixed an issue that caused the ACH and card forms to disappear when a user clicks on certain areas of the form. The forms now display as expected.
* Fixed an issue with card expiration date validation.
