Lua update needed?

[shaffner]

I have successfully downloaded osm.pbf extracts from Geofabrik. But in attempting to get the OSM_Liberty style to work correctly, I had to modify the process-openmaptiles.lua and rebuilt my mbtile file. Then switching to another style, americana (found in Maputnik), I needed several different modifications to the script.

It would seem that the output of lua process is not up to date with the latest openmaptiles schema, now at v4?

Is there an already built lua file update?
