You can now change the weather and optionally set the duration for the new weather! The command is:

/weather [clear | rain | thunder] <time>

You can also look up and change gamerules regarding the Command Block output. The commands are:

/gamerule doFireTick - Whether fire should spread

Nether Portals:

Mobs, items and projectiles now pass through them, preserving momentum. Portals will allow fire burning entities like blazes to leave the Nether and potentially burn things. Portals will teleport an entity relative to where it entered. Nether Portals are now instant for players in Creative mode.


Chickens now use seeds instead of wheat to breed. Pigs now use carrots instead of wheat to breed.

Added & changed many minor things:

Doors, trapdoors, levers and buttons are no longer triggerable with the left mouse button.

World Generation:

Superflat worlds are now customizable. They are now made up of layers specified with block id, data value and height. Biomes can now be changed. Terrain can now be decorated and structures other than villages can spawn.

Default presets:

Classic Flat, Tunnelers’ Dream, Water World, Overworld, Snowy Kingdom, Bottomless Pit, Desert, Redstone Ready.

Witch Huts in swamps has been added. Carrots and potatoes can now be found growing in villages.

Blocks & Items:

Command Blocks:

They run editable commands when triggered by redstone. Intended for adventure maps. Only obtainable using /give playername 137. Can operate in silent mode where it doesn’t display commands in the chat box.


They are intended as an endgame block. Continuously glows and gives a selected status effect to players within 16 blocks while beaming a beacon of light directly upwards (as bright as glowstone). They are activated by building a solid pyramid of iron, gold, emerald or diamond blocks underneath and selecting an effect. The cheapest configuration requires 9 blocks, while the best configuration requires 164 blocks. Has to be directly exposed to skylight to work. Building square platforms of increasing size and the same material per layer will activate it and increase range and status effect selection. Viable materials are iron, gold, diamond and emerald blocks. Changing selected status effects costs 1 emerald, diamond, gold ingot or iron ingot.

Unlockable effects, with increasing amount of required layers of blocks required:

Speed and Haste, Resistance, Jump Boost and Strength.

When all 4 layers of blocks underneath are built correctly, a second status effect can be chosen. This second status effect is Regeneration or tier II of the previously chosen effect. Effects given by the Beacon will have less intrusive particles than others on the screen, such as those of potions.


They are used for repairing and combining enchanted items as well as for renaming any item or block for experience levels. Tools can also be repaired using one piece of their material. Enchantments that are the same are upgraded by one level as long as they are both the same level and the higher level exists. Conflicting enchantments will be removed and only the first one will be kept. They become damaged from using and dropping it. Damage persists in inventory and splits up into 3 categories: Anvil, Slightly Damaged Anvil & Very Damaged Anvil. They can be placed in 4 orientations, but can’t be moved by pistons. Experience level cost depends on enchantment levels & rarities, whether the item will be renamed and whether the item has been used with an anvil before. The maximum experience level cost is 39 levels, unless in Creative mode. It is affected by gravity and does 1 heart of damage to mobs and players it falls on per block it fell, excluding the first one. Players killed by a falling anvil cause the death message “Player was squashed by a falling anvil” to appear in chat. Certain blocks are destroyed when an anvil falls on them: levers, buttons, torches, redstone torches, redstone repeaters,flower pots, rails & mob heads


Repeaters can now be locked by powering their sides with another repeater. When locked, they show a little bedrock barrier in place of the delay indicator torch and won’t change their output signal.

Flower Pots:

Lets players plant all kinds of saplings, mushrooms, flowers, cacti, dead shrubs and ferns. Using pick block on it gives the potted plant. Right-click it with something to plant it, hit it to get both back.

Cobblestone Walls:

Available in cobblestone and moss stone variants. They behave like fences. They Connect to each other, to other blocks and to fence gates & have a 1.5 blocks high collision box. They have a different, higher shape in corners and when blocks are placed on them

Wooden Logs:

The placement has been changed, instead of facing the player, it will face the surface it is placed on. Place it on the side of a block to get a sideways log. Place it on the top or bottom of a block to get a topside log.


Now connect to other stairs to form corner stairs

Item Frames:

All items and blocks can be framed. Clocks, compasses and maps function. Maps show only one marker, the frame itself. Mounted maps show markers on copies of that map. Using pick block on it gives the framed item or block, but it only works in Creative.


Added the Wither painting.

Mob Heads:

Mob heads are very rarely dropped when mobs are killed by players. Only drop from Wither Skeletons, but also exist for creepers, zombies, skeletons and players. They can be put on the ground in 16 orientations and hung on walls. Can be worn. Using external editors or mods player skulls can be assigned to specific players. They then have tooltip “Player’s Head”. Add the NBT tag “SkullOwner” -> (player name) on the skull items.


They can now be placed on the top half of blocks. Placement works similar to that of slabs and stairs.


Now stays active for 0.2 seconds longer. New crafting recipe: Only 1 stone block required.

Wooden Buttons:

Additionally can be activated by arrows. Requires 1 wooden plank to craft.


Now spreads more aggressively depending on the difficulty.


TNT is can now be triggered by flaming arrows.


Potatoes can be planted on hydrated soil and drop 1-4 potatoes when fully grown. They can be grown instantly using bonemeal. They can be Smelted to receive a baked potato. Rarely drops poisoned potatoes. Potatoes give 0.5 hunger points, poisoned potatoes give 1 hunger point and have a chance to poison you, baked potatoes give 3 hunger points.


Carrots can be planted on hydrated soil and drop 2-4 carrots when fully grown. Can be grown instantly using bonemeal. Can be crafted surrounded with 8 gold nuggets to get a golden carrot. Carrots give 2 hunger points, golden carrots give 3 hunger points.

Carrot on a stick:

Used to control pigs. When held, it dictates the direction pigs players are riding will head in. Nearby pigs flock towards players holding it. Slowly loses durability when riding pigs. Pigs start slow but end up going about 5 blocks per second. Can be right-clicked to give the pig a short speed boost. This takes up a chunk of the durability. The pigs ‘eat’ the carrot eventually, leaving the player a fishing rod and will require another carrot to continue riding. To craft, the carrot must be placed at a diagonal below the fishing rod.

Pumpkin Pie:

Pumpkin Pie restores 4 hunger points. The crafting recipe is shapeless. Assemble a Pumpkin, Egg and Sugar into the crafting inventory.

Nether Star:

Drops from Withers. Used to craft the Beacon. Glows like an enchanted item.

Invisibility potion:

Invisibility potion now hides the nametag and cape and that mobs only attack you when you walk into them or attack them. It can also make mobs partially invisible, although eyes of some mobs still show.


Maps start out at their closest zoom level and can be extended by adding more paper and show the players who are in the area of the map. Also, you can craft an existing map with another empty map to receive an extra copy of the map.

Leather Armor:

Leather Armor is revamped and can now be dyed.

Mobs and boss:


All hostile mobs will now jump down to players as long as they can survive the fall and they are willing to take more damage when fighting depending on the difficulty.


The wither is a new boss added to minecraft which is a three-headed flying monster killing mobs which are not undead and players. To summon it place 4 pieces of soulsand in a T-shape and place 3 Wither Skeleton Skulls on top. After spawning, it flashes blue, increases health and is invincible for a few seconds – Then it explodes and starts attacking players and mobs. It shoots projectiles that explode on contact. Endermans are not considered undead, and thus will be attacked by the wither. It darkens the sky when spawned in the Overworld.

Wither Skeleton:

The wither skeleton drop bones, coal, and rarely wither skulls. They spawn in Nether Fortresses and all equipped gear is functional – Swords and tools do more damage on attacks, armor protects it. More advanced gear is more likely to spawn with mobs when playing on harder difficulties and rarely drops when the mob is killed by players.


The witch throws splash potions of poison, slowness, weakness and instant damage at players. They also drinks potions of instant health and fire resistance to defend themselves. They drops sticks, glowstone, redstone, gunpowder, sugar, spider eyes, empty bottles & water bottles when killed and spawn in witch huts which are found in swamps.


The bat hangs on the ceiling when idle, starts flying when players come near and spawn in dark caves. They don’t activate pressure plate and tripwire.


The wolves’ collars can now be dyed by right-clicking them with dye.


Zombies will now rarely spawn with armor of all kinds, which are sometimes enchanted, and can pick up dropped weapons. When killed they will drop the weapons they picked up. When wearing helmets, all damage goes to the helmet rather than the zombie itself and they cannot burn. They also can infect villagers and turn them into zombie villagers, same goes to the baby villagers, when infected, they will turn into baby zombie villager. Baby zombies are faster, won’t age, won’t burn up in the sun and can wear armor. A village zombie will turn back to normal when right-clicked on using a golden apple while having the weakness potion effects.


Skeletons will now rarely spawn with armor of all kinds, which are sometimes enchanted, and can pick up dropped weapons. When killed they will drop the weapons they picked up. When wearing helmets, all damage goes to the helmet rather than the skeletons itself and they cannot burn. They sometimes carry enchanted bows when playing on harder difficulties and rarely drop when the mob is killed by players.

Zombie Pigmen:

Zombie pigmen can pick up dropped weapons and when killed, they will drop the weapons they picked up. They also spawn with weapons and armors depending on difficulty. Now rarely carry enchanted golden swords and dropped golden swords which are sometimes damaged.


All villagers of one village can like and dislike specific players and like them base on the amount of times you trade with them or by not hurting them. When the villagers like the player, particles effects can be seen. However, when players are being disliked, the iron golems will turn aggressive towards them. When villagers die (not due to mobs) or while a player is within 16 blocks or when a mob kills a villager, no baby villagers will be produced in the next few minutes. Players can also use emerald to trade with villagers.

Sorry people for the long list, but we had no choice as the update was really big.
