Don:
The old D-Rats info website is outdated (regarding current versions, development and support), IMO.? Here you will find more current information and versions.??? Under releases you will have information regarding development and progress.? ?Maybe Oct 2021 release could work for you until a new install is compiled and distributed.? Also you can run from tar archive but you have to look and read instructions.?
