Redstone Update

The Redstone Update is a planned major update labeled as 1.5. Among the main changes are a number of new redstone-related blocks, including the Comparator, Hopper, Dropper, Daylight Sensor, Trapped Chest, Weighted Pressure Plates and Block of Redstone. A new decorative block - Block of Quartz, crafted from Nether Quartz, was also added. Also included is a Scoreboard system, a new Texture Pack format and a Lighting engine optimization.

The Redstone Update was announced at the Future Updates with the Minecraft PC Team and The Future of Mod API talks at MineCon 2012.

You can watch the Future Updates Minecon 2012 panel here:

Development began shortly after the announcement, with 13w01a. Sixteen development snapshots were released, from to, with a few snapshots being quickly re-released straight after to fix bugs without changing the client version number. Nearer the end of the snapshot cycle for the 1.5 update, Mojang focused primarily on fixing bugs, rather than adding new features.

Mojang originally planned a pre-release of The Redstone Update on February 28, 2013 and the official update in the first week of March. However, the pre-release got delayed as Mojang were trying to fix more bugs before a stable release. With the pre-release on the 7th of March, it was announced that the Redstone Update would be released Wednesday, March 13 (Tomorrow).

Additions

 * 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 Redstones
 * Stores 9 Redstone
 * Emits constant redstone signal
 * 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 Cobblestones 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 you, while a dropper 'throws' items at you
 * Can face all 6 directions, with a different texture when facing up or down
 * Need 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 x 3 = Signal strength
 * Minecart with Hopper
 * Crafting recipe is a hopper on top of a minecart
 * Can only be emptied by passing over a hopper
 * Can pick up items from containers when it passes over
 * Minecart with Spawner entity
 * Only obtainable with world editors
 * Have only the entity not the item
 * Uses the same NBT format as a normal Spawner
 * Minecart with TNT
 * The crafting recipe is 1 TNT and 1 Minecart
 * Triggered by Activator Rails
 * Explodes even more violently the faster it goes
 * In Creative mode when left clicked while moving, the Minecart with TNT explodes
 * Doesn't destroy rails and supporting blocks
 * Still blows up redstone materials
 * 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
 * Linear, so 10 strength signal means twice as many items as a 5 strength signal
 * Nether Brick (item)
 * Obtained by smelting Netherrack
 * Used to make Netherbrick
 * Nether Quartz
 * Picked up when you break or smelt Nether Quartz Ore
 * Is a crafting ingredient for Daylight Sensors and Redstone Comparators
 * Can be crafted into decorative blocks

 * Drops 1 Nether Quartz item when mined
 * Can be smelted in a Furnace to obtain Nether Quartz
 * Can be legitimately obtained by Silk Touch enchantment
 * Drop more when picked up with Fortune enchantment

 * Updated to corner same all other stairs
 * Chiseled Quartz Block
 * The crafting recipe is 2 Quartz Slabs
 * Decorative block
 * Pillar Quartz Block
 * 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 Wood
 * 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 is the same height as a slab. However, five layers of snow has 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
 * Place two sandstone slabs on top of each other
 * The block ID is
