    • Released with enhanced stability and better performance.

    • Fixed a bug rising from Android Oreo Policy Changes. (Sample application has been modified).

    • The four existing, complex product types (consumable, non-consumable, non-recurring subscription(NRS), and auto-recurring subscription) have been simplified into two types (item and subscription).

    • Version 5.0 provides a new API set and does not support the API set from previous versions. The new API set has the following major characteristics:

    Supports Managed Items : As of Version 5.0, the IAP system manages the history of owned consumable items. With this information, the IAP system can prevent items from being repurchased before purchase is completed and guarantees item provision in case of an unexpected event, such as a network or battery problem.

    Owned Product List : This function is used to provide lists of current unconsumed items and available subscriptions, not a purchase history. Upon launching an application, this function calls getOwnedList. If lists of unconsumed items exist, they must be released using the consumePurchasedItems function.

    Product Details : This function provides not only a list of all products, but also a list of requested products

    Pass-Through Parameter : This is a type of transaction ID that a developer creates and sends when there is a payment request, which responds with the same value for the processed IAP payment result and is used to enhance security.
