Just this week, the Electra Team updated its jailbreak for the first time since this Summer, bringing the tool(s) up to version 1.1.0.
Unlike the all-in-one unc0ver jailbreak by Pwn20wnd, the Electra jailbreak is fragmented into two separate tools; one of those supports iOS 11.0-11.1.2 and the other supports iOS 11.2-11.4 beta 3. Regardless, both tools received notable updates.
