Can you add a changelog for new stuff since the 0.16 version? I just found out that you changed the assembler ingredient counts for level 1 and 2s to 3 and 5 ingredients, respectively.
Because of this you can't even craft basic inserters with level 1 assemblers (now they need the small electric engines), was this intended? In the mean time I changed them both back to 6 ingredients in entity-updates.lua.
One other small bug to report: the Silicum Processing research doesn't have the Logistic Science Pack research as a dependency so you can "try" researching it before you even get Logistic Science Packs.
