Not to be confused with Java Edition 1.7.10 or Bedrock Edition 1.17.1.

1.17.10 is a minor update to Bedrock Edition released on July 13, 2021, which added candles, brought additional parity with Java Edition, experimental features for 1.18.0 and fixed bugs.[1][2]



  • Crafted with honeycomb and string.
  • Comes with 16 dyed types and a yellowish non-dyed type.
  • Can be lit by any item that produces fire.
  • Up to 4 can be placed in a single block, similar to sea pickles, for a maximum light level of 12.
    • Only candles of the same color can be placed on the same block.
  • Only one can be placed on an uneaten cake and lit.
    • If any of the cake is consumed, the candle pops off.

Command format[]

  • Used to create multi-page dialogues with branching narratives for NPCs via dialogue JSON files.

Block of Quartz, Crafting Table, Polished Blackstone Bricks, Cracked Polished Blackstone Bricks, and Sculk Sensor
  • Changed the textures to match Java Edition.
Blue Ice and Enchantment Table
  • No longer emits light.
Rooted Dirt
  • Rooted dirt texture is now randomly rotated, matching the behavior of the regular dirt block.
  • Glowing text on signs now has an outer glow, making text in dark colors more visible in the dark.


Dried Kelp, Netherite Axe, Netherite Boots, Netherite Hoe, Netherite Ingot, Netherite Pickaxe, and Netherite Sword
  • Changed the textures to match Java Edition.


  • When fed with a bucket of tropical fish, it will now return to a water bucket instead of a bucket.

  • Axolotls no longer move their tails while playing dead.
  • Drowned attack any nearby axolotl on sight, if the axolotl is not playing dead.
  • Tempted goats now move at the same speed as goats in Java Edition.
  • Goat fall damage reduction is now in parity with Java Edition. (-10 reduced fall damage)
Guardian and Elder Guardian
  • Guardians and Elder Guardians fire their lasers at axolotls when the axolotls are not playing dead.
  • Skeletons now turn into strays after 20 seconds inside powder snow, instead of 45 seconds.

Non-mobs entities[]

End Crystal
  • Changed the models to have three cubes again instead of two, and to match Java Edition.

World generation[]

Bastion remnants
  • Chest loot has been changed.
    • Loot overall was improved; rarer items had their weights increased and many item amounts were increased. Many pools had their rolls increased as well.
    • Removed all "empty" loot entries.
    • Most items with damage had their average durability increased.
    • Added enchanted golden axes, golden carrots, enchanted golden apples, and blocks of iron to various loot tables.
    • Removed iron nuggets from treasure chests.
    • Unenchanted diamond armor in treasure chests is no longer damaged.


  • Added three world upload slots.
    • One world can be active at a time and can be switched between the three world slots.
  • Added a new accessibility icon in the Settings menu.
  • Added the following splash text from Java 1.17-pre1:
    • "[this splash text has been delayed until part 2]"
    • "Contains simulated goats!"
    • "Home-made!"
    • "There's <<a cat on ,my keyboard!~" [sic]
    • "The cutest predator you'll ever meet!"
    • "Now you are thinking with pistons!"
    • "Get to the coppah!"

  • Added query.show_bottom - a query for determining whether or not the entity's bottom is rendered.
  • Added query.death_time - a query for determining the elapsed ticks since a mob started dying.
  • Added math.min_angle - a math expression for minimizing the angle magnitude (in degrees) into the range [-180, 180].
  • Limits writing of chunks unless necessary. Chunks upgraded from older formats will not automatically save when loaded, but when modified (Through blocks or actors, for example) they will be marked for saving
  • Loot chests with Seed = 0 now correctly randomize if placed on the same coordinates.
    • Note that pick blocking a Vanilla loot chest before opening it will now result in identical loot in each copy unless the player set the seed to 0 in the NBT.
Data Driven Mobs
  • Ender dragon and end crystal rendering and animations are now fully data-driven.
  • The horse rendering and animations are now fully data-driven.
    • This work supports all horse variants (horse, mule, donkey, zombie horse, skeleton horse) and all horse versions
  • Graphics hardware that supports a maximum D3D11 feature level of 9_3 or below are no longer supported.
Stability and Performance
  • Added better error handling for JSON parsing. Also added several new content errors for item parsing as well as for loot tables.
  • Incoming client-sync properties for newly seen types will properly register with client-side Actor Property Manager groups.


These additions and changes are accessible by enabling the "Caves & Cliffs" and "Enable GameTest Framework" experimental toggle.



Sculk Sensor
  • A redstone component that detects vibrations.
  • Currently, it does not generate naturally, but natural generation is planned for future versions.
  • Senses vibrations such as block placement, footsteps, and projectiles, and emits a redstone signal.
  • Vibration JE1 BE1 Emits particles when it senses a vibration nearby.
  • A comparator connected to it emits different signal strengths based on what caused the signal.
  • Does not detect ambient weather such as rain.


Goat Horn
  • Dropped by a goat if it rams into a block.
  • When used for a short period of time, it makes a sound identical to the horn heard during raids.

World generation[]

  • Completely overhauled.
  • Now stretch down to Y=-62.
  • Biomes inside of caves introduced such as dripstone caves and lush caves.
  • Contain aquifers, bodies of water with different heights, independent of sea level (Y=63).
    • Aquifers below Y=0 sometimes generate with lava instead of water.
  • Improved old caves to blend in with the new generations of caves better.
  • New noise caves, coming in 2 forms, cheese, and spaghetti.
    • The original caves still exist with their generation slightly tweaked to better blend in with noise caves.
    • Cheese caves have large stone towers stretching from the bottom of the cave to the top.
      • Very large, often large enough to fly with an elytra.
      • Abundant with aquifers and ores.
    • Spaghetti caves are long, thin caves that have small aquifers and are more similar to original caves.
  • Mineshaft pieces no longer generate if they were fully floating in the air.
  • Corridors now generate with wooden logs as pillars for support, or chains and oak fences as hanging support if needed.
  • Cobwebs no longer generate floating without an adjacent block.
Ore distribution
  • Changed ore generation of all ores making them have a spread value like lapis lazuli ore. Some still retain a linear generation alongside a spread generation.
  • Coal ore, emerald ore, and copper ore no longer generate below Y=0.
    • Copper ore generates between the Y=0 and Y=96 and like all other ores, uses spread. It peaks at Y=48.
    • Emerald ore generates above Y=32 as a spread, peaking at Y=256 and decreasing in quantity as the altitude decreases.
    • Coal ore attempts to generate twice: once, evenly between an altitude of Y=136 and Y=256; and as a spread, peaking at an altitude of Y=96 and generating between an altitude of Y=0 and Y=192.
  • Other ores also generate differently.
    • Iron ore attempts to generate three times: once as a spread peaking at an altitude of Y=256, generating above Y=128; another as a spread peaking at Y=16 and generating with a minimum height of Y=-24 and a maximum height of Y=57, and a smaller one spreading evenly between the altitudes of Y=-64 and Y=-32.
    • Gold ore generates between the altitudes of Y=-64 and Y=32, peaking at Y=-16. The extra gold that generates in the badlands biome was left untouched.
    • Lapis lazuli ore attempts to generate twice: once, as a spread between the altitudes of Y=32 and Y=-32, peaking at an altitude of 0; and evenly between the altitudes of Y=64 and Y=-64, generating buried like ancient debris.
    • Redstone ore attempts to generate twice: once, evenly between an altitude of Y=15 and Y=-64; and as a spread, peaking at an altitude of -64 and generating below an altitude of Y=-32.
    • Diamond ore now generate as a spread, generating below Y=16 and peaking at altitudes near y=-64.
  • Tweaked size and positioning of diorite, andesite & granite generation.
    • Pockets of diorite, granite, and andesite are now larger and more spherical but less common.
