As you can see in the attached screenshot there is a new field that there wasn’t in previous Unity versions.
We always have problems settings the appropiate value using Jenkins:
PlayerSettings.macOS.buildNumber = buildNumber.ToString(); // Only for macOS
PlayerSettings.iOS.buildNumber = buildNumber.ToString(); // Only for iOS
PlayerSettings.Android.bundleVersionCode = buildNumber; // Only for Android
PlayerSettings.WSA.packageVersion = new Version(versionString); // Only for WSA
PlayerSettings.bundleVersion = versionString; // Only for Android & iOS
// There is no built-in way for setting it on WebGL
Is there in 2018.3 beta a new API for settings it in a unified way?
