This page covers a pre-release version that has an issue under certain conditions.

This version crashes on startup if the options.txt file does not already exist.^[1]

1.21.11 Pre-Release 1 (known as 1.21.11-pre1 in the launcher) is the first pre-release for Java Edition 1.21.11, released on November 19, 2025.^[2]

A separate unobfuscated version of 1.21.11 Pre-Release 1 was released, titled 1.21.11 Pre-Release 1 Unobfuscated (or 1.21.11-pre1_unobfuscated when in the launcher). This is an experimental version released in preparation for obfuscation being removed from Java Edition clients and servers.^[3]

Additions

General

Data component format

Added minecraft:attack_range
- Enables a custom attack range when using the item.
- Overrides the normal entity interaction range for player.
- Regular melee attack range is computed for mobs based on the distance of the target hitbox to their hitbox. This component modifies that distance check by adjusting minimum and maximum padding for the attack hitbox.
- Mobs using minecraft:kinetic_weapon will have their attack range applied in the same way it applies to players.
- Format: object with fields
  - min_reach: float, the minimum distance in blocks from the attacker to the target to be considered valid.
    - Default value: 0.0, valid from 0.0 to 64.0
  - max_reach: float, the maximum distance in blocks from the attacker to the target to be considered valid.
    - Default value: 3.0, valid from 0.0 to 64.0
  - hitbox_margin: float, the margin applied to the target bounding box when checking for valid hitbox collision.
    - Default value: 0.3, valid from 0.0 to 1.0
  - mob_factor: float, the multiplier applied to the min_range and max_range when checking for valid distance when item is used by a mob.
    - Default value: 1.0, valid from 0.0 to 2.0

Settings

Added texture filtering in video settings.
- Controls the method used to sample textures when they are viewed at an angle or from a distance.
- Available values are "None", "RGSS", and "Anisotropic".
- The default depends on the selected graphics preset as well as the computer's graphics card capabilities.^{[note 2]}
- "RGSS" (Rotated Grid Super Sampling) is a shader-based filtering method that improves texture clarity at a moderate performance cost.
  - This is available on all hardware.
- "Anisotropic" is a hardware-based filtering method that improves texture clarity even further.
  - The maximum anisotropy may be "2x", "4x", and "8x", controllable by a separate slider.
  - If the graphics card does not support it, anisotropic filtering will do nothing.
  - This significantly impacts VRAM usage (especially combined with a high mipmap count).

Splash

Added "Music by Hyper Potions!"

Changes

Items

Leather horse armor

The texture is now the same as in Bedrock Edition.
Both the item and the equipment assets have been split into a tinted base layer and an overlay layer.

Spears

Changed the swap animation scale of all spears from 1.9 to 1.95.^{[source code ref 1]}
The player can now continue to deal damage to the target if they keep charging at it after the initial hit, and mobs can do the same.
Golden spears are now a piglin-preferred weapon.
Skeleton variants and drowned no longer pick them up.
Zombified piglins can now charge with the spear and not just jab with it.
Spears are now placed after swords in the Creative inventory.

Mobs

Camel Husk

No longer sink in water while ridden by a player.

Nautilus and zombie nautilus

The heads of the Nautilus and Zombie Nautilus now clip less through their shells.
Baby Nautilus now uses nautilus swimming sounds instead of fish swimming sounds (entity.fish.swim).
The nautilus shell drop is now affected by Looting.

Gameplay

Advancements

The "Mob Kabob" advancement is now a goal advancement instead of a challenge advancement.

General

Data component format

min_reach, max_reach and hitbox_margin have been moved from minecraft:piercing_weapon and minecraft:kinetic_weapon into a new component minecraft:attack_range to allow all melee weapon types to use them.

Data pack

The pack format version is now 94.0.

Resource pack

The version is now 75.0.

Tags

Entity Type Tags
- Added camel_husk to #can_float_while_ridden tag.
Item Tags
- Added golden_spear to #piglin_preferred_weapons tag.

Textures

texture section of *.mcmeta files has a new alpha_cutoff_bias field that controls alpha bias for cutout textures.
- There is no limit for this value technically, it can be negative as well, but it does not make sense to set this higher than 1.0 or lower than -1.0 since the texture will become either fully opaque or fully transparent.
- Default value for this field is 0.0, and it can be increased for textures that can become too transparent/thin at distance, or decreased if it's too "opaque".
- Only used for lower mips of cutout textures, does not change the alpha of first mip level, and has no effect on other textures.
