Hi there!
Today Epic has already approved the new version of the tool, so it’s already available on the marketplace to be downloaded and compatible with UE 4.24. I have added some very interesting new options, which has been added to UE 4.24 Ray Tracing feature by Epic 
As this is a tool exclusively designed for Ray Tracing use, and RT on Unreal is still a beta version, it’s suffering some different changes in the Engine on every version they release, so I think it’s a good decision to discontinue previous versions of the tool, which were compatible with previous UE versions, when Epic releases a new one version with significant internal changes on Ray Tracing features, like this time, with UE 4.24. So, I mean that this time my tool (v7.0) have been updated only for the UE 4.24. UE 4.23 and 4.22 of my tool (v6.0) will not receive more updates, as the better RT settings are in UE 4.24 (or in the last UE4 released version), having no more sense to use previous Unreal ray tracing versions (but if some people still want to do it, they can still download and work with the last released version of my tool, v6.0, for UE 4.22 and 4.23, which was working perfectly too).
The decision of this is simple: UE 4.24 has introduced some new features on ray tracing that made necessary to make some special changes to my tool, so I would need to have and make two different versions of the tool, one for the previous v4.22 and 4.23 and a different one for the new 4.24, and sent them to Epic and be separately approved every time I would update it. In the future it will be the same: if with the same version and code I can do it work with the newer and the previous versions, I will maintain both versions updated, but if a new version introduces significant changes that makes me the need to develop two different branchs, the oldest will be discontinued (but still perfectly functional, as it has been until now). This may happen one more time, maybe, as Epic is still working on RT and it’s still on beta, but when it comes retail, it won’t probably introduce anymore those ‘significant’ changes I was talking about, making my tool compatible with all UE versions released from that Ray Tracing ‘retail’ moment.
So, from now:
Up to RTX RayTracing easy global settings tweaker v6.0: compatible with UE 4.22 and 4.23
From RTX RayTracing easy global settings tweaker v7.0: compatible with UE 4.24 and above
Regards!
