There are plans to port the jailbreak to higher firmware versions up to 6.x but due to the additional security measures this could take a considerable amount of time. Unfortuantely for those consoles on 6.x and 7.x firmware versions this webkit exploit has been patched but potential blu-ray related exploits are being considered.
The UMTX jailbreak allows users to unlock the PS5 debug menu and even provides users an entry point to inject small (limited) payloads such as a basic Hello World! test that has succesfully been run.

While some users might be disappointed by the current limitations, this release is a major step forward for PS5 jailbreak development, opening the door to further discoveries and potential exploits in the future.
