6.3.3 build 1068 vs 6.3.3 build 2252

I noticed that my new Surf SOHO MK3 came with firmware 6.3.3 build 1068, but that the latest firmware version released on the Peplink website (and that my old Surf SOHO MK2 is running) is firmware 6.3.3 build 2252.

Is there any reason NOT to upgrade the MK3 with the 2252 build? Is there any reason to upgrade the MK3 to the 2252 build? I’m happy to leave the MK3 “as is” until the next version release.
