SKAdNetwork: "version 2.0" availability

"version 2.0" is available for apps built with iOS 14 sdk, what does this mean?
Is it the source app showing ads needs to be built with iOS14 OR advertised app needs to be built with iOS 14 OR both? And are those apps needs to be running on iOS 14 device or they can be running on iOS 13 and below?

OR does this mean source app and/or advertised app running on iOS14 will be able to use "version 2.0" ?
You receive a version 1.0 postback if the source app uses a pre-iOS 14 SDK, or if the advertised app is running on a device with an iOS version prior to iOS 14. Otherwise you will receive version 2.0

I meant to ask 'source-app-id' and 'conversionValue' fields. If source app is iOS 14 SDK but advertised app is pre-iOS 14 SDK. Can adnetwork still get 'source-app-id' in postback?

Similarly, if source app is pre-iOS 14 SDK but advertised app is iOS 14 SDK, can adnetwork get 'conversionValue' in postback?
Hi Rajesh, yes ‘source-app-id is eligible to be in the postback even if installed app isn’t using iOS 14 SDK or newer.
with the latter question, if the source app is using pre-iOS 14 SDK then postback will be version 1.0, thus no source-app-id nor conversionsValue
