v1.21:

Added null check for empty ingredients (courtesy of Drowsy Corgi)

v1.20:

Removed Harmony logging

v1.19:

Added new code that controls how pawns consume gourmet meals. Now a pawn will try to avoid consuming a meal if he is under the effect of a condiment, instead choosing a different one (code provided by Drowsy Corgi)
Added new code that disables the "hidden tolerance" effect on desserts. All drugs are affected by tolerance, even if not shown on the health panel, and desserts need to be a drug to be scheduled. This code resets that hidden tolerance mechanic to 0 every time a colonist consumes a dessert (code provided by Drowsy Corgi)
Changed item processor DLL with a null array check so cheese presses don't create any more problems.
Changed item processor DLL so that temperature controlled machines display their temperature range in C, F or K depending on the user preferences. Centigrades is the only sensible choice, though.
Added Harmony as a mod dependency

v1.18:

Added a period to IP_TempRangeInThisMachine to separate sentences
Tweaked ItemProcessor to avoid inspect string problems in cheese press
Added Stack by Ingredients to gourmet desserts

v1.17:

Modified ItemProcessor.dll to support temperature, rain and light checking
Adjustes scaling optimality for Grills so pawns prefer fresh grills over other meals in the same meal category (simple, fine, etc)
Addes chocolate as an available ingredient for desserts fine through gourmet
Changed grilling research to Medieval
Modified simple bakes to be made with flour only
Added a "condiments to kibble" bill to the condiment prep table so it no longer counts as a workshop building, but as part of a kitchen
Canned foods are now sellable

v1.16:

Fixed a bug in Item Processors where ingredient lists were being accumulated between processes
Fixed typo calling "Well Fed" a debuff instead of a buff in grill meals
Set desserts to stackCount of 10, like other meals, instead of 75

v1.15:

Fixed an issue where resetting the recipe of an electric pot caused the reset button to then be active on sucessive runs, thus resetting the recipe all the time
Electric pot, stew pot and cheese press graphics will now continue showing the pot / wooden lid until the product is removed by a colonist
Added 4 days spoilage to desserts like all other meals
Reduced cost of canning fish to 1 Steel (from 5) per 20 cans
Fixed rotation of canned food when eating at a table
Added optimality offset to gourmet meals so they are prefered to lavish. Added negative offset to fried food so colonists prefer simple meals:
Gourmet > Lavish > Fine > Simple >Fried > Canned
Changed soup nutrition to 0.6 - 0.7 - 0.8 (was 0.7 - 0.7 - 0.9). Gourmet is unchanged
Increased wheat yield to 18 (was 14)

v1.14:

Added CompProperties_StackByIngredients to uncooked soups so they don't stack with different ingredients, creating unnecessarily long ingredient lists

v1.13:

Tweaked condiment price values so they produce a net gain from their ingredients

v1.12:

Added countdown timer of 1 day to the hediff added by Mechanoid Cheese
