I am freezing Opensim-Aura at version 1.1 and polishing it before moving to dotnet10.

Opensim-Aura is focused on HyperGrid Simulators rather than closed grid config.
If you want to test it you can download the latest release at:
https://github.com/amandaleeang/OpenSim-Aura/releases

Implemented so far:
- Attachment scripts running after HG teleport
- Server side bakes (Firestorm SSA)
- Distributed UUID among participating grids’ nodes, (UUID DHT (HyperGrid UUID locator)
- HG visitors’ assets stay in cache only, not in the db.
- Concurrent HTTP requests
- Xbakes use outfit deterministic ID instead of uuid
- Improvements to HG Friends, HG IM, HG Profiles, HG Group Profiles
- Display Names, HG compatible with Aura sims.

For Stand alone:
- HG groups in Sqlite
- HG Offline messages in Sqlite
- FSAssets for Standalone and Sqlite
