Protocol version


1.4.6 introduced fireworks, enchanted books and the Thorns enchantment. It also added a warning for users playing on soon-to-be unsupported systems (PowerPC and Java 5). While it was not the last update to 1.4, it was the last one before the snapshots of 1.5 started.



Nether brick slabs
  • Crafted much like other slabs, using nether brick


Enchanted books
  • Enchant books to receive a single enchant on them
  • Can be applied to items using anvils, consuming the book – Enchants can be applied to any item in Creative
  • Sold by villagers and found in dungeon and village chests
  • Can now be found in loot chests and by trading with villagers
  • Unbreaking can be applied to anything with durability
  • Efficiency and Silk Touch can be applied to shears, allowing the harvesting of cobwebs
  • Sharpness, Smite, and Bane of Arthropods can be applied to axes
Firework star
  • Used to create firework rockets
  • Combine gunpowder with dyes to get a firework star with those colors used for the sparkles
  • Also add glowstone, a fire charge, a diamond, a gold nugget, feather, or a mob head to make the firework twinkling, big, trailing, star-shaped, bursting, or creeper-shaped
  • Craft a firework star with dye to change the color the sparkles fade to
Firework rocket
  • Non-destructive, rise up in the air, and create colorful patterns when shot by dispensers or placed by players
  • Combine paper with gunpowder to get a firework rocket
  • Also add a firework star to add effects or gunpowder to increase the flight duration


Thorns enchantment
  • Armor enchantment
  • Deals damage depending on tier to attackers
  • Wears armor out more quickly.



Monster spawners
  • Can now spawn differently configured mobs with different spawn chances


  • A sound indicates when you hit a player with an arrow
  • Arrows now render from farther away


  • Fireballs' blast radius can now be customized
Skeletons, zombies, and zombie pigmen
  • The armor and enchants they spawn with now are even harder on harder difficulties

World generation[edit]

Dungeons and villages
  • Now have a random chance to have enchanted books in their chests.


  • You can drag and drop items – Press long to halve the stack before dragging
  • Fire Protection now extinguishes fire more quickly
  • Blast Protection now reduces explosion recoil
  • Protection is not as protective as it used to be in order to make specific enchantments more worthwhile
Minor improvements
  • Made item drops and framed items render in 3D when using fancy graphics
  • Items now show their name when switching in the hotbar
    • Can be disabled by changing heldItemTooltips to false in options.txt
  • Right-clicking while sneaking now uses the held item instead of the selected block
  • Dropping items while holding ctrl now drops the whole stack
  • Death messages now appear in server log files


  • Added a default resolution setting – options.txt: overrideWidth:0 and overrideHeight:0
