Released on December 12, 2013 for Minecraft 1.6.4.


 * NEW: Add Lamps.
 * NEW: Added MultiPart support for Bricks/Cubes/Glass.
 * NEW: Add Creosote Block variants of Stairs and Slabs.
 * NEW: Tagged a bunch more stuff with Thaumcraft 4 Aspects.
 * CHANGE: Reworked Boiler math to eliminate heat-up costs.
 * Boiler Changes:
 * Goal: Provide a more realistic interpretation of real life Boiler physics.
 * Steam Produced becomes a factor of Heat. Steam per cycle per tank = STEAM_PER_UNIT_WATER * (temp / maxTemp)
 * Fuel use less dependant on temp, higher temps need more fuel. Fuel used per cycle per tank = FUEL_PER_BOILER_CYCLE + FUEL_HEAT_INEFFICIENCY * (temp / maxTemp) + FUEL_PRESSURE_INEFFICIENCY * (maxTemp / 1000)
 * Differences between Low/High:
 * Max Temp (Low=500, High=1000)
 * Ticks Per Cycle (Low=16, High=8)
 * Efficiency bonus per tank remains similar.
 * Heatup times remain similar, but add/remove heat functions are smoothed out.
 * Heat Up: newTemp = oldTemp + (HEAT_STEP + (((maxTemp - temp) / maxTemp) * HEAT_STEP * 3) / numTanks
 * Cool Down: newTemp = oldTemp - (HEAT_STEP + ((temp / maxTemp) * HEAT_STEP * 3)) / numTanks

New Code:


 * Code as present in Version 8.3.0.0:


 * Code as present in Version 8.3.2.0:


 * Heat Adjustment Code (one of these two following functions are called once per tick):

Current Fluid Fuel Values as of 8.3.0.0:
 * Biofuel/Ethanol = 16k HU
 * Fuel = 48k HU

 * CHANGE: Fuel adjustments: Blaze Rods 800->1000, Coal 3200->1600, Coke 6400->3200, Coke Block 57600->28800 (fixes Short overflow issues with furnaces).

 * FIX: Carts can't collide when dead, fixes some issues with Nether Portals.
 * FIX: Various minor performance tweaks to Boilers, Rolling Machines, etc...
