   I figured out the changes required, which we can manually make as a workaround before Foreman updates.

   In the foremanexport mod, the following changes are required:

   1. LuaRecipePrototype.category and LuaRecipePrototype.additional_categories were consolidated into LuaRecipePrototype.categories. In instrument-control.lua:

   trecipe['category'] = recipe.category
   trecipe['additional_categories'] = {}
   if recipe.additional_categories ~= nil then
   	for _, cat in ipairs(recipe.additional_categories) do
   		table.insert(trecipe['additional_categories'], cat)
   	end
   end

   should become

   trecipe['additional_categories'] = {}
   for i, cat in ipairs(recipe.categories) do
       if i == 1 then
           trecipe['category'] = cat
       else
           table.insert(trecipe['additional_categories'], cat)
       end
   end

   Either that, or the way Foreman models categories should be updated to match Factorio 2.1's.

   2. For the same reason,

   add_category(recipe.category)
   if recipe.additional_categories ~= nil then
   	for _, cat in ipairs(recipe.additional_categories) do
   		add_category(cat)
   	end
   end

   should become

   for _, cat in ipairs(recipe.categories) do
       add_category(cat)
   end

   3. The properties LuaEntityPrototype.pumping_speed, LuaEntityPrototype.fluid_usage_per_tick, and LuaEntityPrototype.max_power_output were removed, so accesses should be replaced with LuaEntityPrototype.get_pumping_speed(), LuaEntityPrototype.get_fluid_usage_per_tick(), and LuaEntityPrototype.get_max_power_output() respectively.

   4. The way that recipes define fractional outputs has changed. Instead of defining ItemProduct.probability, it has ItemProduct.independent_probability and ItemProduct.shared_probability. The two places that calculate

   ((product.probability == nil) and 1 or product.probability)

   should be replaced with

   (product.independent_probability * (product.shared_probability.max - product.shared_probability.min))

   5. In info.json, update "factorio_version" from 2.0 to 2.1 and "base" from 2.0.7 to 2.1.7.

   There may be other changes for features that only mods use, but with these fixes it appears to make a completely correct preset for Factorio Space Age 2.1.9.

   In addition, Foreman 2.4 is unaware that the quality mod has been split into quality and recycler, so it throw a mod consistency error. As a workaround, this can be fixed by removing the recycler mod from the game's install directory and adding it to the mod folder. For the next Foreman release, DataCaching.IconCacheProcessor.PrepareModPaths should have the recycler mod added to the list of mods included with the game.

   After testing his suggested workaround (it worked) I made a fork and pull request with those suggested changes. I didn't try compiling the C code itself so the IconCacheProcessor.cs change is untested.

    Import indeed fails on 2.1.14
    IconCacheProcessor needs to be updated for the 'recycler' mod (as it has hardcoded base game mods)

    // line 78 (hard to notice as very long single line, bad formatting, 
    // maybe replace with a IsBaseFactorioMod helper function or readonly map like 'recycler' => '__recycler__' 
                        if (foundFile == null) {
                            if (!string.Equals(mod.Key, "core", StringComparison.OrdinalIgnoreCase)
                                && !string.Equals(mod.Key, "base", StringComparison.OrdinalIgnoreCase)
                                && !string.Equals(mod.Key, "elevated-rails", StringComparison.OrdinalIgnoreCase)
                                && !string.Equals(mod.Key, "recycler", StringComparison.OrdinalIgnoreCase) // add 
                                && !string.Equals(mod.Key, "quality", StringComparison.OrdinalIgnoreCase)
                                && !string.Equals(mod.Key, "space-age", StringComparison.OrdinalIgnoreCase))
                                return false;
                            continue;
                        }

    Also ideally this part should consider ProductMinor and have 1/2/2.1 exporters to avoid breaking 2.0 compat

    string foremanModName = "foremanexport_" + factorioVersionInfo.ProductMajorPart + ".0.0";
