According to the changelog for AltServer 1.4.9 Compatibility iOS 15.4 RC, this version includes an essential fix for a crashing issue for iOS or iPadOS 13 or older devices.

While those on iOS or iPadOS 14 or 15 can use the integrated “Update” button in the app to quickly and simply update to the current version of AltStore, the AltStore team strongly advises those on iOS or iPadOS 13 or older to update AltStore by re-sideloading the latest version with AltSever.

The updated version of AltStore should give a better user experience with fewer unexpected app crashes once loaded, which is one of the reasons why ipsw.me suggests that all current users update to the latest version of AltStore whenever they choose.

There is currently no update for the computer-based AltServer application, as today’s upgrade solely affects the handset-based AltStore app.

While many jailbreakers use AltStore to sideload the Odyssey, Taurine, and unc0ver jailbreak apps, it’s also popular among those who want to sideload their own. IPA files are used to get around the App Store’s often crippling limitations. Modified apps, unregistered apps, and even gaming emulators are frequently involved.
