Would seem so. The project is open source, and nobody is getting paid. So the lack of update makes sense to some extent.
As cool as it is.. and as much as I want to make plex shove it completely. Jellyfin just isn't ready for prime-time.
I run both... Jellyfin isn't allowed to talk outside of my network at all, and I can access it over my personal VPN... But Plex is where all my users are because anything else would just be too annoying to maintain.
