Meridian

Meridian is a semi-untethered jailbreak for all 64-bit devices running iOS 10.0-10.3.3, primarily developed by PsychoTea, with extensive contributions from others. Meridian works by sideloading an IPA using Cydia Impactor or using TotallyNotSpyware through Safari. The first public beta of Meridian was released on 4 January, 2018.
