Upcoming Jailbreak

Uncover - Uncover is the most reliable semi-untethered jailbreak since iOS 11 to iOS 12.1.2 versions. It is the only iOS 12 jailbreak released so far. The developer Pwn20wnd has continuously updated the Unc0ver tool. So, Uncover Jailbreak can be considered as upcoming iOS 12.3 jailbreak.
He is currently working for the adding Cydia for the Unc0ver iOS 12 - iOS 12.1.2 jailbreak running A12 devices.
Even, if he released Unc0ver Jailbreak for iOS 12.3, iOS 12.2, iOS 12.1.3 or iOS 12.1.4 we can not expect these jailbreak for iPhone XS, XS Max, XR devices. The developer has tweeted that as iOS 12 - iOS 12.1.2 is the last jailbreak for A12 devices.
Rootless JB - Jake James released Rootless Jb for 12.1.2 to iOS 11.2. This Jailbreak does not install Cydia or any jailbreak app package manager. However you can install Jailbreak tweaks with Rootless Installer.
Most probably, he update the Rootless Jb for iOS 12.3 too.
Nowadays he also trying to add A12 devices compatibility for Rootless JB. He is working on that and recently tweeted as it is going to be success. However, Pwn20wnd has replied that is already patched and it’s really hard to jailbreaking these devices.
Hexxa - Hexxa is newly released jailbreak app installer. Currently this the only iOS 12.2 Jailbreak repo extractor. It will install most popular Jailbreak apps/ tweaks on iOS 12.2. As well it install Cydia many other app manager too. Also, you can install Apricot iOS through Hexxa  to get the virtual Jailbreak experience.

Hence this is newly introduced there is more chance to Hexxa upgradement for iOS 12.3.

Their very first Pangu untethered Jailbreak for iOS 7.1 and iOS 9.3.3 in the last version they have involved. Since then they did not attend to any official pangu tool released.
