From the start my prior PR was aiming at compatibility with legacy clients and servers. If you scan the MT forum you will become aware that there seem to be quite many MT 0.4 servers around which are actively used by many players.
However, the best solution may be this example of a new piece of improved code, if I understand the MT Lua code correctly.
```
-- print to log after mod was loaded successfully
local load_message = "[MOD] XXX loaded"
if minetest.log then
minetest.log("info", load_message) -- aims at state of the art MT software
else
print (load_message) -- aims at legacy MT software used in the field
end
```
Hope this helps.
