Good morning Illia,
sorry for the late reply. It looks like there is no current
development to update NASDAQ ITCH, and you could open an issue similar
to that one created a while ago for NASDAQ OUCH (
https://gitlab.com/wireshark/wireshark/-/work_items/15312 ). Following
this, updating the existing dissector and submitting an MR that we
would happily review. Please note joining some PCAP to the issue makes
things easier for the review.
I suppose version 5 also covers the changes of version 4, so jumping
directly to version 5 should be fine.
Regards
E.A.
