With Wireshark 4.0 there is an opportunity to make more sweeping 
changes. One of those is moving to Lua 5.3 or 5.4 (and only one of those).

Lua 5.3 has some important enhancements (bit ops, 64 bit integers and a 
basic utf-8 library).

Lua 5.4 introduces a new garbage collector.

New Lua minor versions are not 100% backward-compatible so some amount 
of breakage for existing Lua code is to be expected when moving from 
Wireshark 3.6 to 4.0, if this move goes ahead.

Reference for each Lua release: https://www.lua.org/versions.html

This message is intended to solicit feedback from the community about 
that change, whether it should happen and which Lua version is preferred 
for Wireshark 4.0 (between 5.3 and 5.4).

Thanks.
