NEWS

Grin Node meets UmbrelOS, Embassyos updates. Forum Message from contributor wiesche
- I have completed the first port to the UmbrelOs environment.
- I had to make a few adjustments to the nodes (cli parameter transfer).
- All containers are available in arm64 and amd64 (Rust grin, grin++, Node Controller).
- I have also adapted the UI so that you can now use the website on your cell phone.
The following things are still pending:
- GUI improvements
- Complete functional test
- Long-term test
- Configuration test or mainnet
If anyone has time for a test in their Umbrel environment in the next 2-3 weeks, please feel free to contact me. (@wiesche)
