Dopamine jailbreak updated to version 2.2 with memory improvements, configurable jetsam multiplier, & more…

Anyone who uses the Dopamine jailbreak for iOS & iPadOS versions 15 or 16 may be interested in knowing that there’s a new update to the jailbreak as of early Sunday morning.

Dopamine v2.2 announced by developer Lars Fröder.

In a post shared to social media platform X (formerly Twitter), Dopamine project lead developer Lars Fröder (@opa334dev) shared a post in which he had announced Dopamine version 2.2, which appears to contain a slew of improvements and bug fixes for users.

Citing the official change log, Dopamine v2.2 brings us the following changes over the previous version:

– Remove DYLD_INTERPOSE in favor of other hooking techniques, since DYLD_INTERPOSE was apparently causing memory usage to be much higher than what it should be
– The jetsam multiplier can now be configured inside the Dopamine app, in previous Dopamine versions this was 3x everywhere with no option to configure it, due to the removal of the DYLD_INTERPOSE, the default setting has been able to be lowered to 2x
NSTask is now supported everywhere by default, unlike before where it was only supported inside tweak dylibs or when you called dopamine_fix_NSTask yourself
– Due to the better hooking techniques, a lot of unnecessary code has been able to be removed
– Fix kcall on iOS 15 arm64 not working from libkrw and iDownload
– Fix frida-ps -U panicing the device (To be honest, I have no clue what change actually fixed this, the only thing I know is that it happens in older Dopamine versions and doesn’t happen in 2.2 anymore)
– Improve launchd crash reporter in various different ways
– Code cleanup

As it would appear, Dopamine v2.2 not only improve memory handling, but also allows users to configure the jetsam multiplier and improves the jailbreak’s code thanks to better hooking techniques. As a result, Dopamine is more efficient and should be more reliable.

If you’re already using the Dopamine jailbreak, then you will be able to update without a computer by simply launching the Dopamine jailbreak app and following the “Update Available” prompts from within the app, as shown:
