User sceneries RC8/9 all download links dead

I stumbled onto this site on the ikarus homepage (don't actually know how you can navigate to it) but it seems all user generated sceneries can't be downloaded anymore, all links to the .zip files are dead: https://www.ikarus.net/user-szenerien-rc8-rc9/

What about all those additional user sceneries and the work that the community has put into those?
I read that they can't be directly imported into RC10 (at least a few months ago in October 2023)?
I really would like to extend the available collection of RC10 sceneries, really sad to see all those nice user generated content seems to be just vanishing...
Also, I can't find any current infos on available modding SDKs + HowTos for creating custom content for RC10..
Everything I found is dating back to RC7, 8 or 9.. What's up with that?

The website is currently being updated, so that the downloads also work for RC10. We hope to have this website updated soon.

Thanks for the info! Looking forward to that. Please keep us updated on the progress.
Will there also follow a RC10 SDK and updated information on how user generated content (especially sceneries) are now created for RC10 from scratch (and how older sceneries are converted) - or at least updated information on what might have changed in the workflow?
