As far as I know yes. All I did was run apt update && apt upgrade and the jellyfin packages were downloaded/upgraded.

The UI says it is as well:

I'm getting a similar error message, although the log points to not having a path to ffmpeg..

Just upgraded to 10.8 in Docker on Linux

EDIT:
I was able to fix it by setting the path in Playback settings to:
/usr/lib/jellyfin-ffmpeg/ffmpeg

Yes, for 10.8.0 reverting back to /usr/lib/jellyfin-ffmpeg/ffmpeg fixed it. I also had issues with Debian 11 main stream ffmpeg, with hardware accelerations enabled, the conversion rate dropped from 70fps to <5fps which made the client waited took too long for playback to start.

@AnonymousWebHacker commented on GitHub (Nov 29, 2022):

Fixed:

It is only to specify in Settings / Playback, the path of the ffmpeg binaries (for transcoding), and that of ffprobe (test the videos, and extract extension, format, time of the video ..etc)

/usr/bin/ <--- This is ok
