It’s just a check on the version number. As per my previous link, Void’s FreeRDP is still stuck on 2.x, whereas 3.x stable came out last December, with the latest stable being v3.4.0, released 3 weeks ago.
Nix also fails this test btw, since they too are still stuck on 2.x - and this is an example I’ve been using often as an argument against Nix fanbois who tend to claim that Nixpkgs is equivalent or even superior to the AUR, when in reality that’s not the case.
The reason why I’m so interested in 3.x is because it’s a major upgrade with a ton of QoL improvements. Any serious RDP user will want to switch to FreeRDP 3.x, especially if they’re a Wayland user / game over RDP /use RemoteApps (eg WinApps) etc. So I check the FreeRDP version of a distro as an indicator whether that distro is worth my time or not, hence why I call it the “freerdp test”. 3.x is also consider stable release btw, so there’s really no excuse for a distro not to package it and at least make it available - perhaps with a new name so as to not force an upgrade, if they’re concerned about compatibility issues.
nixpkgs is holding out with it because it’s part of the current GNOME 46 draft pull request: https://github.com/NixOS/nixpkgs/issues/282102
Though I agree it’d have made more sense to migrate to freerdp 3 earlier and have two versions available, like with pipewire.
There’s also a nix file in that discussion with a more recent version.
