+## Version 5 & 6 Major Update
+* This version of the plugins now target .NET 6! (Still including support for Xamarin). Versions 5 & 6 are the same source code, but Version 5 doesn't include 6.0. I would recommend this version for Xamarin apps.
+* Android: We now use Google Play Billing Version 4.0!
+* iOS: Beta - In version 4 we auto finalized all transactions... you can no turn that off in your iOS application with `InAppBillingImplementation.FinishAllTransactions = false;`. This would be required if you are using consumables and don't want to auto finish. You will need to finalize manually with `FinalizePurchaseAsync`
+* All: There are now "Extras" for all products that give you back tons of info for each platform
+* Android: `AcknowledgePurchaseAsync` is now `FinalizePurchaseAsync`

 ## Version 4 Major Update - Android
 
 We now use Xamarin.Essentials for getting access to the current activity. So ensure you [initialize Xamarin.Essentials](https://docs.microsoft.com/xamarin/essentials/get-started?WT.mc_id=friends-0000-jamont) in your Android app.
