Development versions




Client (.json)

1.4.6 introduced fireworks, enchanted books and the Thorns enchantment. It also added a warning for users playing on soon 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.



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

Blocks & Items[]

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



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


  • 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

World Generation[]

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

Blocks & Items[]

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
