21w07a is the tenth snapshot for Java Edition 1.17, released on February 17, 2021,[1] which adds grimstone and tweaks ore and cave generation.
Additions[]
Blocks[]
- A new type of stone.
- Generates below Y=0.
- Has a gradual transition from stone to grimstone starting from Y-level -1 until it reaches -8.
- Takes over fully underground starting from Y=-8.
- Functions identical to cobblestone and blackstone in that grimstone can be used to craft basic tools, furnaces and brewing stands.
- Can be used as a decorative block.
- It can be crafted into many different variants. Chiseled grimstone, polished grimstone, grimstone bricks, grimstone tiles.
- Has a hardness value greater than that of stone but can be mined with any pickaxe.
- Can't be insta-mined unlike stone.
General[]
- Data Packs
- Added grimstone_enabled to
worldgen/noise_settings/*.json
.
Changes[]
Blocks[]
- Slightly changed model.
- Blackstone, polished blackstone bricks, and cracked polished blackstone bricks and stair, slab and wall variants
- Slightly changed the texture.
- Can now naturally generate on grimstone.
- The textures of coal ore, diamond ore, gold ore, iron ore, and redstone ore have been changed.
- All overworld ores except diamond, lapis lazuli, emerald, and copper had the shape of the "ore pattern" in the stone changed to make them visually distinct for colorblind players.
- Diamond ore remains the same as it was the most iconic one of the ores that used this shape.
- Beacon beams are now visible up to 1343 blocks away from the source instead of 256 blocks.
World generation[]
- Noise caves and aquifers appear less often.
- Mineral distribution
- Changed ore generation of all ores making them have a spread value and generate in a triangle distribution[2] 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 (up to Y=480 in custom worlds) 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 twice: once as a spread peaking at an altitude of Y=256, generating above Y=128 (up to Y=384 in custom worlds); and another as a spread peaking at Y=32 and generating with a minimum height of Y=-16 and a maximum height of Y=80.
- 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 an altitude 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 (down to Y=-96 in custom worlds).
- 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.
- Grimstone now generates as the dominant stone below Y=0.
- Corridors are now supported by chains and oak fences above when the layer is nearer to the ceiling than the floor.
- Wood pillars are now made of logs instead of wood.
General[]
- Creative inventory
- The Redstone Tab has been reordered to prioritize highly-used blocks.
- Redstone items/blocks have been grouped and ordered in the following way (from top to bottom): Essentials, Unique activators, Miscellaneous, Common activators, Openables.
- Data Packs
- Vanilla configured features for ore types have changed:
- Coal and iron have been split into two parts called
_upper
and_lower
- New lapis configured feature:
ore_lapis_buried
- Coal and iron have been split into two parts called
- The
glow_lichen
feature now lists grimstone as a valid block. - Changes to the
range
decorator configuration:bottom_offset
,top_offset
andmaximum
fields removed- Replaced with
bottom_inclusive
andtop_inclusive
which are both a new type of vertical anchoring - This type can have several forms:
absolute
- specifies an absolute y valueabove_bottom
- specifies an offset above the minimum y coordinate of the worldbelow_top
- specifies an offset below the maximum y coordinate of the world
- The
range_biased
andrange_very_biased
feature decorator are now calledrange_biased_to_bottom
andrange_very_biased_to_bottom
respectively.- Both biased types of ranges now have
bottom_inclusive
andtop_inclusive
of the same type, and acutoff
value that's a numeric value
- Both biased types of ranges now have
- The
depth_average
decorator also now has its baseline field as a vertical anchor instead of an absolute y value. - A whole range of decorators no longer exist or have had part of their functionality replaced by using some of the already existing generic decorators:
dark_oak_tree
decorator no longer does a heightmap check, needs to be done with aheightmap
decorator- The
end_gateway
decorator has been split, now used with a combination ofchance
,square
&heightmap
- see theend_gateway configuration
in the vanilla pack for an example - The
glowstone_blob
feature no longer does its own decoration, instead is used with a combination ofsquare
&range
. Seeglowstone_extra
in vanilla files for example. - The
lava_lake
feature has also been split, now used withchance
,square
, andrange_biased_to_bottom
. Seelake_lava
for an example. - The
water_lake
decorator has been removed. Now insteadchance
,square
&range
- The
emerald_ore
decorator has been removed. Now insteadcount
,square
&range
- The
fire
decorator has been removed. Now insteadrange
,square
&count
- The
carving_mask
no longer has a probability field, replaced with achance
decorator
- Added grimstone to the
base_stone_overworld
block tag and thestone_crafting_materials
, andstone_tool_materials
item tags. - Added various grimstone variants to the
slabs
,stairs
, andwalls
block and item tags.

- MC-214928 – Mineshaft corridor support pillars are made out of wood, not logs.
- MC-214973 – Powder snow bucket in a dispenser at Y=319 facing upwards or at Y=-64 facing downwards is replaced with empty bucket, despite no powder snow being placed.
- MC-214986 – Large dripstones only generate as stalagmites below Y=0.
