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.
Previously, AltStore would quit all other processes when first accessing the database no matter what. However, this unintentionally caused the widget extension to quit the main app after refreshing apps.
Now, we only quit other AltStore processes if a database migration is required. This still prevents multiple AltStores with different database schemas from accessing database concurrently, but also allows extensions to access database without quitting main app.
AltStore now sends a “WillAccessDatabase” notification before loading the persistent store, which causes other AltStore instances in memory to exit (either immediately, or upon returning to foreground).
This prevents multiple AltStore instances from simultaneously accessing the same database, which could result in corrupted data (especially if they used different database model versions).
We now set AppVersion.sourceID during migration, which fixes AppVersion entries conflicting across different Sources if multiple contain the same app + version.
Rather than store both the current user’s Patreon account and all cached Friend Zone patrons in the same table, we now store Friend Zone patrons in the new ManagedPatron table. This avoids the need to distinguish between the two at runtime.
The Patreon API doesn’t have a way to fetch just the patrons belonging to our Friend Zone tier. Instead, we need to fetch ALL patrons (including inactive ones) and filter out those not in the tier. This is very inefficient, and takes over a minute to complete as of April 14, 2022, due to the number of patrons we have.
We can’t do much to change this, but AltStore will now at least cache the fetched patrons with Core Data. Additionally, AltStore will only perform this long fetch whenever the Friend Zone list actually changes, rather than every time the Patreon screen appears.
Previously, only the beta version of AltStore could add sources. Now, the public version supports adding explicitly “trusted” sources, while the beta version can continue to add any source.
