==Additions==
===Blocks===
; Activator Rail
*The crafting recipe is 2 sticks, 6 iron ingots and 1 redstone torch.
*Used to trigger minecart with TNT.
*Used to stop item passing on minecart with hopper.
*Needs to be powered by redstone.
*Transmits redstone signal to 8 activator rails far. 
; Block of redstone
*The crafting recipe is 9 redstone.
*Emits constant redstone signal, the same as a redstone torch.
*Works as pushable redstone power source. 
; Daylight sensor
*The crafting recipe is 3 wooden slabs, 3 nether quartz and 3 glass blocks.
* Outputs a signal with a strength corresponding to the intensity of the sun.
*Only works with the sun's light (not man-made light such as torches).
* Rain affects the sensor's output.
; Dropper
*The crafting recipe is 7 cobblestone and 1 redstone.
*Places items in containers in front of them, if there is no container it will dispense the item without using it.
*A dispenser "shoots" items at the player, while a dropper "throws" items at the player.
*Can face all 6 directions, with a different texture when facing up or down.
*Needs redstone signal to drop items.
*Fires once when the input becomes powered.
*Redstone signal emitted when a redstone comparator is placed against it directly - signal length depends on its fullness.
; Hopper
*The crafting recipe is 5 iron ingots and 1 chest.
* Places and takes out items in hoppers, chests, furnaces, minecart with chests, minecart with hoppers, dispensers, droppers, and brewing stands.
*Allows for the automation of many processes collecting drops.
*Powering the hopper stops it from taking in items and releasing them.
*Redstone signal emitted when a redstone comparator is placed against it directly - signal length depends on its fullness.
** 1 item will give a signal strength of 1, a third of a stack (21 for items which stack to 64) gives a signal strength of 2.
**The number of full stacks × 3 = Signal strength. 
; Redstone comparator
*Based on the idea of the capacitor mentioned at Minecon 2012.
*The crafting recipe is 3 redstone torches, 1 nether quartz and 3 stone.
*It is the same as a repeater, but with 2 inputs.
**If input A is stronger or equal to input B, it either repeats the signal or outputs the difference between A and B, so this can be used as an easier way make redstone contraptions like piston doors.
***Output is toggleable by right-clicking.
**If input A is weaker than input B, then there is no output.
*All containers output a redstone signal when a redstone comparator is placed against it directly. The strength of it depends on how full the container is and what disc number is used in a jukebox.
**This works with trapped chests as well, meaning it can provide two redstone signals with different causes at the same time.
; Trapped chest
*The crafting recipe is 1 chest, and 1 tripwire hook.
*Gives out a signal depending on the amount of players looking inside.
*Large trapped chests can be staggered with large chests to allow more compact storage.
*Transmit signal downward through one block. This does not apply horizontally.
*Texture is slightly different than a normal chest, with a red stain around the latch. 
; Weighted pressure plate
*Used to detect item drops.
* Gold (light) version reaches full strength at 60 items.
* Iron (heavy) version reaches full strength at 600 items.
* Proportional, so 10 strength signal means twice as many items as a 5 strength signal.
; Nether quartz ore
*Drops 1 nether quartz item when mined.
*Can be smelted in a furnace to obtain nether quartz.
*Can be legitimately obtained with Silk Touch enchantment.
*Drop more when mined with Fortune enchantment. 
; Block of quartz
*The crafting recipe is 4 nether quartz in a square.
*Decorative block.
; Quartz slab
*The crafting recipe is 3 blocks of quartz.
*Can be placed upside down.
*Decorative block.
; Quartz stairs
*The crafting recipe is 6 block of quartz in a usual stair recipe.
*Can be placed upside down. 
; Chiseled Quartz Block
*The crafting recipe is 2 quartz slabs.
*Decorative block.
; Quartz Pillar
*The crafting recipe is 2 vertical block of quartz.
*Decorative block.
*Pillar quartz blocks can be placed sideways, using the side of the block to place similar to sideways log.
; Multiple snow heights
*Fully implemented - previously, a world editor could be used for different heights of snow.
*Drops one snowball for every layer of snow.
*Each level of snow has its own height collision.
**The topmost layer of snow does not have collision, so the player is always slightly sunken in the snow.
**Visually, four layers of snow are the same height as a slab. However, five layers of snow have the same collision height as a slab.
*Crafting recipe is 3 snow blocks in a row to create 6 snow layers.
**For each thin layer of snow crafted, the player loses exactly half the snowballs required to produce it.
; Sandstone double slab 
*The block ID is 43:9.
===Items===
