I have been given update on this at our Discord server with some frequency, but we have put this on hold until we can get more details on the upcoming changes on the engine’s rendering module (which changed quite a lot and still will), so we have placed priority on releasing the last update on Cloudscape Seasons and increasing efforts to finish our Ocean Seasons, since there is a lot (lot more) of requests on this.
We expect to have a next update as soon we can see the changes on UE4.23 and probably it will get the development resumed where it stopped after UE 4.23 launch.
