so, was installing the usual jellyfin-media-player flatpak on a new install as I did so many times, mistyped and was presented with a list of jellyfin related apps. there's a new Jellyfin Desktop app in there that def wasn't there before, has the official sounding org.jellyfin.JellyfinDesktop id.

installed it, looks the same. haven't caught that in the news feeds I follow, so what's the story there, what's different from the iwalton3 thingy?

$ flatpak install jellyfin
Looking for matches…

edit: so far, works as drop-in replacement, functionality is the same and command line switches work (e.g. I have a shorcut that launches it in TV mode on a 4K screen with --fullscreen --tv --scale-factor 2). the UI is noticeably faster and it plays some HEVC files that were glitching out on same hardware.
