M-DISC (blu-ray) users, what version of UDF are you using and why?

Question

Data archiving

I decided to record a photo-video archive on a blu-ray M-DISC (25GB), I could not find the final answer on the net which version of UDF is better to use for archiving purposes. Who can share their experience in this matter?
PS: I'm currently using UDF 2.5

Answer 1

UDF has not been updated for a hundred years at lunch, use the latest 2.6 and don't worry.
The file system usually does not care what is stored on it (well, except for exotics like XFS or BTRFS there).
