Before, whether or not the source included the buildVersion affected the comparison. If present, the buildVersion was used in comparison, if not, only the version itself was used for comparsion.
This meant it was impossible to update from a version with a buildVersion to the same version without one (e.g. going from betas to final releases). Now we _always_ consider the buildVersion in the comparsion, so an earlier entry in versions array without buildVersion can be considered “newer” even if versions match.
AltStore will now consider an update available if either:
* The source’s marketing version doesn’t match installed app’s version
* The source declares a build version AND it doesn’t match the install app’s build version
The installed app matches an app version if both maketing versions match, and the build versions match (if provided by the source).
The MacDirtyCow exploit allows users to remove the 3 active apps limit on iOS 16.1.2 and earlier. To support this, we’ve added a new (hidden) “Enforce 3-App Limit” setting that can be disabled to allow sideloading more than 3 apps.
We now store the latest supported version as a relationship on StoreApp, rather than the latest available version. This allows us to reference the latest supported version in predicates and sort descriptors.
However, we kept the underlying Core Data property name the same to avoid extra migration.
