Java Edition 26.3 Snapshot 6

26.3 Snapshot 6 (known as 26.3-snapshot-6 in the launcher) is the sixth snapshot for Java Edition 26.3, released on July 28, 2026,^[1] which tweaks the abandoned camps, makes technical changes, and fixes bugs.

Entity data

• Added invulnerable_time tag which makes a mob temporarily invulnerable for a specific number of ticks.

Options

• Added Quit Shortcuts option.
  • Can be accessed in the Controls section.
  • Allows keyboard shortcuts that close the game, such as ⌥ Alt + F4 on Windows and ⌘ Command + Q or ⌘ Command + W on macOS.
  • Disabled by default.

Abandoned camp

• Added a new campsite variant for each biome.
• Minor tweaks to abandoned camp structures.

/publish

• The gamemode argument has been removed.
  • Instead, the default game mode of the world should be set using the /defaultgamemode command or the Game Mode button in the World Options screen, while player-specific game modes should be set using the /gamemode command.

Data component format

• minecraft:cooking_fuel
  • burn_time and speed_multiplier can now additionally be defined by an inline number.

• minecraft:brewing_fuel
  • uses and speed_multiplier can now additionally be defined by an inline number.

• minecraft:compostable
  • layers can now additionally be defined by an inline number.

Data pack

• The pack format version is now 113.0.

Equipment assets

• The trim_palette_replacements field has been replaced with trim_overrides. This can be used to swap out the texture or palette used with specific trim materials or patterns for a given equipment asset, not just swap specific palettes.
  • Format: list of override entries with fields:
    • when – object with fields, the material and/or pattern to match.
      • material – optional trim material ID, the material to match (if specified).
      • pattern – optional trim pattern ID, the pattern to match (if specified).
        • Note: this is not the palette ID, as trim_palette_replacements used to be.
      • At least one of material or pattern must be specified.
      • If both are specified, both must match for the entry to be used.
    • texture – optional trim pattern asset ID, a replacement texture to use if this entry matches.
      • Textures are specified in the same format as asset_id
      • If not specified, the default texture for the pattern will be used.
    • palette – optional palette ID, a replacement palette to use if this entry matches.
      • If not specified, no palette remapping will be applied to the texture.
    • The first matching entry will always be selected.
    • At least one of texture or palette must be defined.

Loot table types

• minecraft:block_interact
  • origin is now available in context, as the center of the block being interacted with.

Rendering

• Terrain blocks are now rendered with MultiDrawIndirect on supported devices.

Resource pack

• The version is now 94.0.

Settings

• The World Options button has been moved to the Game Menu where the Open to LAN button used to be, replacing it.
  • The World Options screen is divided into two sections: "General" and "Multiplayer".
  • The "General" section contains the same options as the previous World Options screen.
    • The Lock World screen has been changed.
  • The "Multiplayer" section contains three options:
    • LAN: changes the multiplayer scope of the world.
    • Command Access: Controls whether players that join a world can use commands or not.
    • Port: the port number to use when opening the world to LAN.
• The Online button used to access the Online Options screen will now always be shown in the Options menu.

Shaders

• terrain.vsh and terrain.fsh shaders are refactored to support multi-draw.
• Some of the members in Globals and DynamicTransforms are shuffled to use less memory for those uniform blocks.
• Introduced new define: RENDERPEARL_EXPLICIT_DEPTH_INVARIANCE – if present, indicates that an OIT shader should explicitly output a depth value because a device it is running on can produce a slightly different implicit value.

World generation

• Noises
  • The format of noises (defined in the worldgen/noise registry, or inline in noise-based block state providers) has been updated.
  • Noises define a fractal brownian motion configuration with the following properties:
    • Produces output values (approximately) fitting a normal distribution.
    • Unless otherwise specified, fits the output amplitude to [-1; 1]
      • Due to the normal distribution, in practice this means that 99.7% of all samples will fit in that range – but values may still be encountered outside of this range.
    • Parameterized by persistence=0.5, lacunarity=2.0
      • i.e. between each octave, the amplitude is halved and the frequency doubled.
    • Has stable seeding such that an octave can be boosted, muted, or added without affecting the rest of the octaves.
    • Renamed firstOctave to base_octave.
    • Added base_amplitude – non-negative float, a scale factor to apply to the noise output.
      • If not specified, defaults to 1.0.
    • Added octave_count – integer between 1 and 32, the number of octaves to sample.
    • Added normalize – boolean, or "legacy", controls how the output amplitude should be normalized.
      • If true, base_amplitude is the expected amplitude of the output (i.e. 99.7% of all samples in [-base_amplitude; base_amplitude])
      • If false, base_amplitude is the amplitude of the first octave.
      • If "legacy", inherits the same normalization behavior as expressed by the previous format.
        • This would generally fit to a range smaller than expected.
      • If not specified, defaults to true.
      • Note: normalization is not affected by the amplitude_modifiers field – as such, modifying the amplitude of a single octave will not affect the amplitude of others.
    • Renamed amplitudes to amplitude_modifiers – list of floats, a scaling factor to apply to each octave.
      • The number of elements in this list must match octave_count.
      • As described above, this scaling factor bypasses normalization and will affect the output amplitude.
      • This field is no longer required – if not specified, defaults to all 1.0.
• Density functions
  • Added pow
    • Raises the given base value to an exponent.
    • Format: object with fields:
      • base – density function, the base value.
      • exponent – density function, the exponent.
  • Added sqrt
    • Computes the square root of the given input.
    • Format: object with fields:
      • input – density function, the value for which to compute the square root.
  • Added log
    • Computes the natural logarithm of the given input.
    • Format: object with fields:
      • input – density function, the value for which to compute the natural logarithm.
  • Added sign
    • Computes the sign of the input:
      • If the input is positive, returns 1
      • If the input is 0, returns 0
      • If input is negative, returns -1
    • Format: object with fields:
      • input – density function, the value of which to compute the sign.
  • Added distance_to_point
    • Computes the distance to a fixed point using the specified distance function.
    • Format: object with fields:
      • point – array of 3 integers in form [x, y, z], the point to compute distance to.
      • metric – one of:
        • euclidean – i.e. ${\displaystyle sqrt(d{x}^2+d{y}^2+d{z}^2)}$
        • euclidean_squared – i.e. ${\displaystyle d{x}^2+d{y}^2+d{z}^2}$
        • manhattan – i.e. ${\displaystyle abs(dx)+abs(dy)+abs(dz)}$
        • chebyshev – i.e. ${\displaystyle max(abs(dx),abs(dy),abs(dz))}$
  • Updated gradient (renamed from y_clamped_gradient)
    • Format: object with fields:
      • axis – x, y, or z, the axis over which to define this gradient.
      • tiling – one of:
        • clamp_to_edge – outside the gradient boundaries, the value at the nearest boundary will be used.
        • repeat – the gradient will be repeated outside its boundaries.
        • mirrored_repeat – the gradient will be repeated such that odd repetitions are mirrored, ensuring continuity between repetitions.
      • from_coordinate – int, the coordinate at which the gradient starts.
      • to_coordinate – int, the coordinate at which the gradient ends.
        • Must not be equal to from_coordinate
      • from_value – float, the value at which the gradient starts.
      • to_value – float, the value at which the gradient ends.
  • Added slice
    • Removes a dimension from the input domain by taking a "slice" along an axis with a specific coordinate. For example, with axis=y and coordinate=0, a slice will be taken along the XZ plane, with all values sampled at y=0.
    • Format: object with fields:
      • axis – x, y, or z, the axis to remove.
      • coordinate – int, the fixed coordinate to be passed to the input function.
      • input – density function, the input function.
  • Changed end_outer_islands
    • Renamed from end_islands. No longer computes the density of the main island.
• Structure pool elements
  • Changed minecraft:feature_pool_element
    • Can now connect to jigsaw blocks with any target name, instead of just minecraft:bottom.
