iOS 15, macOS Monterey, and JIT Support (Patreon)

Been a while since my last update, hope you've all been enjoying playing Nintendo DS games with Delta!

As some of you may know, the first iOS 15 beta was released to developers last week, and unfortunately it introduced a new code signature version that prevented AltStore and any sideloaded apps from launching. The good news is I've spent the past week reverse engineering this new code signature version, and I believe I've finally cracked it 🥳 As a result, AltStore 1.4.6b and AltServer 1.5b5 are now available, and bring full support for sideloading apps on iOS 15!

While I've confirmed my fix works to install both AltStore and Delta on iOS 15, I need y'alls help testing as many apps as possible to ensure my fix covers all edge cases. If you've already updated to iOS 15, you must manually update AltStore by downloading the attached AltServer beta and using it to re-install AltStore (you do not need to delete AltStore first). If you are still on iOS 14, you can update AltStore normally in-app.

Additionally, this macOS AltServer beta includes two additional features. Besides adding support for macOS Monterey beta 1, AltServer for macOS also includes the brand new "AltJIT" feature, which allows you to enable JIT compilation for any app on iOS 14 or later (including iOS 15). For now, you can manually enable JIT for any sideloaded app by selecting it from the "Enable JIT" menu option (as seen in the above screenshot), and soon I will release a framework developers can integrate with their apps that will allow them to automatically enable JIT whenever they're on the same WiFi as AltServer. As for Windows, I plan to include AltJIT support in the next AltServer beta.

As always, thanks everyone for your help testing! Once I've confirmed this code signing fix works for all apps, I plan to release this update to everyone else ASAP 🙏
