tshark statistics (-z) now print like 919kB rather than integers

edit

when I use tshark (latest version 3.4.0) command like

tshark -q -r one.pcapng -z conv,tcp

then it prints like

1.1.1.1 <-> 2.2.2.2 10141 919kB 10111 14MB 20252 15MB 0.000000000 4.5453

however, in older version (e.g. 3.2.2), it does not print bytes, kb, mb, just number without anything.

1.1.1.1 <-> 2.2.2.2 10141 919480 10111 14805918 20252 15725398 0.000000000 4.5453

I cannot find any message about this new feature in help docs. I guess there might be some option to decide print format. Do someone know the answer?
