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.
fix inventory_plus after cleanup. Create own register_on_player_receive_fields for this inventory
removed smart_inventory (moved to the inventoy mod), adjusted sfinv
moved sfinv to own mod 3d_armor_sfinv
moved unified_inventory to 3d_armor_ui
moved inventory_plus support to own mod 3d_armor_ip
