## Discussion

Use `“2.0”` as the version number when signing ads for this version.

Ad networks are eligible to receive a version 2.0 postback if all three of the following conditions are met:

- The source app generates a signature for version 2.0.
- The source app is built with the iOS 14 SDK or later.
- The advertised app is App Store-signed and running on a device with iOS 14 or later.

When verifying an install-validation postback for version 2.0, use the following Apple P-192 public key:
