# SKAdNetwork 2.2 release notes A version of SKAdNetwork available in iOS 14.5 and later. ## Discussion Use `“2.2”` as the version number when signing ads for this version. Ad networks are eligible to receive a version 2.2 postback if all three of the following conditions are met: - The source app generates a signature for version 2.2. - The source app is built with iOS 14.5 SDK or later. - The advertised app is App Store-signed and running on a device with iOS 14.5 or later. ### New features New features include: - You can now create view-through ads using the new APIs [`SKAdImpression`](/documentation/StoreKit/SKAdImpression) , [`startImpression(_:completionHandler:)`](/documentation/StoreKit/SKAdNetwork/startImpression(_:completionHandler:)), and [`endImpression(_:completionHandler:)`](/documentation/StoreKit/SKAdNetwork/endImpression(_:completionHandler:)). - You can now indicate whether an ad is a view-through ad or a StoreKit-rendered ad by using the new `fidelity-type` parameter. The `fidelity-type` value is `0` for view-through ads, and `1` for StoreKit-rendered ads. You include this parameter when you sign an ad, and receive it in the postback. For more information about view-through ads and `fidelity-type`, see [Signing and providing ads](/documentation/StoreKit/signing-and-providing-ads) and [Generating the signature to validate view-through ads](/documentation/StoreKit/generating-the-signature-to-validate-view-through-ads). For more information about the postback, see [Verifying an install-validation postback](/documentation/StoreKit/verifying-an-install-validation-postback). --- Copyright © 2026 Apple Inc.
