This update also includes other important updates, including Randomize Bundle IDs which may help with “provisioning profile is banned.”
Thanks to kisnner26 and whydr4 for their help with the -80045 fix 💚

AltStore: an alternative app store for non-jailbroken iOS devices (15k stars)
What it does
All text below is quoted directly from the project README.
>AltStore is an alternative app store for non-jailbroken iOS devices.
Features:
- Installs apps over WiFi using AltServer
- Resigns and installs any app with your Apple ID
- Refreshes apps periodically in the background to prevent them from expiring (when on same WiFi as AltServer)
- Handles app updates directly through AltStore
- AltStore is an iOS application that allows you to sideload other apps (.ipa files) onto your iOS device with just your Apple ID.
- AltStore resigns apps with your personal development certificate and sends them to a desktop app, AltServer, which installs the resigned apps back to your device using iTunes WiFi sync.
>AltStore and AltServer are both fairly straightforward to compile and run if you're already an iOS or macOS developer.

AltServer on macOS 27 can sign in again (fix for -80045 / "The data is not in the correct format")
If AltServer on macOS 27 fails with -80045 or, since Oct 14, "The data is not in the correct format", here's what's going on and a fix.
Why: on macOS 27 AltServer generates Android anisette data. Apple first rejected it with -80045, and now answers any request that declares an Android client with a 503 HTML page, which AltServer shows as the format error. It's not your password or your account.
What works: Windows anisette data from an anisette v3 server (ani.jkcoxson.com), with the client info and user agent that server reports. iloader 2.3.8 uses the same approach.
Fix for AltServer: I opened a PR, AltStore#1834 (+ AltSign#61). Tested on macOS 27.2: sign-in, 2FA and AltStore 2.3 installed on iPadOS 27.2. Until it's merged and released, iloader 2.3.8 is the easiest option if you need to sideload now.
Tips: use a 2FA code generated on a trusted device (Settings > your name > Sign-In & Security > Get Verification Code). SMS fails right now. Don't retry over and over: Apple rate-limits you (429/503). Some accounts still get -80045 even with Windows anisette.
