Changelog

Version: 2.0.7
  Changes:
    - Building quality boilers won't create a copy of the item anymore
    - Added a migration script to clean up dublicated items (matching items on the ground at the exact same positions as qualifying boilers)
    - Fixed the formatting of the changelog so it can be viewed ingame

Version: 2.0.6
  Changes:
    - The big burner has the advertised 18 pollution per MW now

Version: 2.0.5
  Changes:
    - Pollution stays the same on higher quality machines with higher power output
    - Fuel efficiency increases by 15% per quality level
    - On vanilla boilers and oil boilers, increases the target temperature by 30% per quality level (requires steam turbines to take advantage of the increased power output)

Version: 2.0.4
  Changes:
    - Fixed a bug with the parse_energy function
    - reduced gas pollution by 10% (updated 2.0.1 changelog accordingly

Version: 2.0.2
  Changes:
    - Increased fluid fuel values by 50%, adjusted fluid consumptions down so everything else stays the same
    - To match this, solid fuel has now a fuel value of 10.8 MJ
    - burner generator power decreased by 0.05MW, efficiency up from 0.5 -> 0.7
    - big burner generator efficiency increased from 0.66 -> 0.8
    - decreased diesel pollution 0.8 -> 0.7
    - diesel recipe now takes 10 petroleum gas instead of 20
    - reduced train and vehicle pollution
    - updated the 2.0.1 changelog accordingly

Version: 2.0.1
  Changes:
    - Fuel Values / Emissions:
    - Crude Oil 1.4 MJ -> 0.48 MJ / 1.4 -> 1.4
    - Light Oil 1.5 MJ -> 1.08 MJ / 1.2 -> 1.1
    - Heavy Oil 1.0 MJ -> 0.60 MJ / 1.3 -> 1.3
    - Petro Gas 1.5 MJ -> 0.90 MJ / 1.0 -> 0.45
    - Diesel    2.0 MJ -> 1.50 MJ / 0.8 -> 0.7 
    - Non-fluid Emissions (instead of 1.0):
    - Wood 1.1, Coal 1.0, Solid fuel 0.9, Rocket fuel 0.8, Nuclear fuel 0.7
    - Solid fuel fuel value 12 MJ -> 10.8 MJ
    - Entities:
    - Vanilla boiler (for reference): 1.8 MW, 100% fuel efficiency, 16.66 Polution/MW
    - ... Small Burner: 
    - Efficiency: 25% -> 70%
    - Emissions: 60/MW -> 22/MW
    - Power: 0.5 MW -> 0.7 MW
    - ... Big Burner: 
    - Efficiency: 50% -> 80%
    - Emissions: 20/MW -> 18/MW
    - ... Diesel Generator: 
    - Efficiency: 100% -> 85%
    - Emissions: 12.5/MW -> 8.25/MW (multiplied with fuel emissions)
    - 4 MW Power only with Diesel fuel, less dense fuel types = less power and emissions
    - ... Oil Boiler:
    - Still 100% efficiency
    - Emissions: 7.4/MW -> 3.7/MW (multiplied with fuel emissions)
    - Now only needs 2 steam engines or 1 steam turbine instead of +1 each (165 -> 240° temperature)
    - ... Steam Engine:
    - Now accepts 240° hot steam instead of 165. With vanilla boilers it may not appear saturated because those only produce 165° hot steam, but they still produce the same with them
    - ... Other Changes: (OPTIONAL ! Check startup Settings)
    - Disabled wind turbine (k2-wind-turbine looks better, or my "windturbines" mod is more realistic. pick one of those)
    - Burner Cars and tanks and hovercrafts pollute now 1/20000 of their base fuel consumption per minute. 600kW -> 30 pollution/min for example (tank)
    - Trains (seperate setting) now pollute 25 per minute (15 for diesel trains if that mod ever gets updated)
