Cyanide 1.6.6

Fixes

• Hide Labels on iOS 17 is now instant and durable (#7). No more flash on swipe — every page comes up already hidden — and Keep Cyanide Alive is no longer needed: you can fully close Cyanide and the labels stay hidden. iOS 18+ unchanged.

About A18 / M4

On A18 / M4 devices a run has about a 50/50 chance of rebooting the device (a
kernel "panic") instead of succeeding — a known limit of these chips that can't
be fully fixed. It's a coin flip, so if it reboots, just try again; a few
attempts usually gets there. Once a run works, it stays working until your next
restart.

If you keep hitting panics, Settings → Launch Options has four knobs for the
A18 chain — exploit path (pe_v1 / pe_v2), memory shaping, interleaved search
and bounded search. Defaults are unchanged in this release; other combinations
may do better on your device. Each applies to the next fresh run.
