Preset format with example: 95;35:2;2x20;1;stronghold – 95 is the format version, followed by a semicolon and the layer information. Every new layer is separated by a comma and must consist of the block id (35) and can additionally have :2 appended to specify 2 as the data value. Before that, you can put 2x to specify that this layer should be put 2 times. After a semicolon follows the biome id. After another semicolon follow all structures to be generated, including their options.

Blocks & Items
Command blocks
Runs editable commands when triggered by redstone
Intended for adventure maps
Can only be edited by OPs, as long as enable-command-block in server.properties is enabled
Only obtainable using /give playername 137[21][22]
Can operate in silent mode where it doesn't display commands in the chat box. [23]
Beacons
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)
Activated by building a solid pyramid of iron/gold/emerald/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 and Jump Boost
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
Used for repairing and combining enchanted items as well as for renaming any item/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
Becomes damaged from using and dropping it - Damage persists in inventory and splits up into 3 categories: Anvil, Slightly Damaged Anvil & Very Damaged Anvil
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 - Maximum experience level cost is 39 levels, unless in Creative mode[25]
For a more detailed explanation on how enchantments are combined using the anvil, see the Anvil mechanics page
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

Each head can fire projectiles, so called Wither Skulls, at different targets - Projectiles explode on impact
Shoots two kinds of projectile - a blue one from the little heads, targeting mobs and a dark one from the big head targeting players
