+## Migration guide for Version 4.x.x
 - The `themeColor`, `textColor`, and `cursorColor` properties have been removed from `CreditCardForm` due to changes in how it detects and applies application themes. Please check out the example app to learn how to apply those using `Theme`.
 - The `cardNumberDecoration`, `expiryDateDecoration`, `cvvCodeDecoration`, and `cardHolderDecoration` properties are moved to the newly added `InputDecoration` class that also has `textStyle` properties for all the textFields of the `CreditCardForm`.
