Barnabas, Thank you! Barnabas Beres 写道: > * gnu/packages/games.scm (simgear): Update to 2020.3.2 > * gnu/packages/games.scm (flightgear): Update to 2020.3.2 Unfortunately, this patch is incomplete: you'd expect at least one hash change, and in this case 3 (simgear, flightgear, and its data). Unfortunatelier, I updated Flightgear to 2020.3.2 when it came out (patch below) but haven't been able to test it yet, so it's been rotting away on my hard drive. Have you successfully flown the new version? It adds yet another a third-party library but I kept is as it's been ‘modified’ according to the README. I didn't compare the code. Kind regards, T G-R
