The good news is that version Chimera 1.2.4 works in iOS 12.3. However, there is one caveat - only some beta versions are supported. The chance that someone on the device has a suitable beta version of iOS 12.3 is very small. However, the lucky ones now have the opportunity to jailbreak.
Like Unc0ver, Chimera does not support 4K devices like the iPhone XS, iPhone XR and iPad Pro 2018 with iOS 12.2. These devices are only supported with versions of iOS 12 - iOS 12.1.2.
If you already have Chimera jailbreak installed, you can update it by downloading the new version.
