-* Updates compileSdkVersion to 31.
+* Deprecated the `InAppPurchaseAndroidPlatformAddition.enablePendingPurchases()` method and `InAppPurchaseAndroidPlatformAddition.enablePendingPurchase` property. Since Google Play no longer accepts App submissions that don't support pending purchases it is no longer necessary to acknowledge this through code.
+* Updates example app Android compileSdkVersion to 31.
