Qnap / out of date Duplicacy version

Hello, I am glad to use Duplicacy on my box (QNAP) for some years and it matches quite well my backup requirements. I usually keep a winning team together^^. Local store on USB SSD that I copy to HDD every once in a while

I know this question as been on the table at some stage with QNAP, but the version on their s/w store is not updating, stuck at duplicacy web v1.4.2 et CLI at v3.2.5.

I am unsure if I should upgrade manually the package on my box, so - I guess my question is

  • is there a particular reason ( critical bugs) for upgrading to lattest version if I need no new features ?

Thank you for any feedback and have a great day
