Minecraft:Java Edition 1.21.11 Pre-Release 1

1.21.11 Pre-Release 1 (known as 1.21.11-pre1 in the launcher) is the first pre-release for Minecraft:Java Edition 1.21.11, released on November 19, 2025.<ref>Template:Mcnet</ref>

A separate Minecraft: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 Template:JE clients and servers.<ref>Template:Mcnet</ref>

Additions

General

Minecraft:Data component format

• Added Template:Cd
  • 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 Template:Cd will have their attack range applied in the same way it applies to players.
  • Format: object with fields
    • Template:Cd: float, the minimum distance in blocks from the attacker to the target to be considered valid.
      • Default value: Template:Cd, valid from Template:Cd to Template:Cd
    • Template:Cd: float, the maximum distance in blocks from the attacker to the target to be considered valid.
      • Default value: Template:Cd, valid from Template:Cd to Template:Cd
    • Template:Cd: float, the margin applied to the target bounding box when checking for valid hitbox collision.
      • Default value: Template:Cd, valid from Template:Cd to Template:Cd
    • Template:Cd: float, the multiplier applied to the Template:Cd and Template:Cd when checking for valid distance when item is used by a mob.
      • Default value: Template:Cd, valid from Template:Cd to Template:Cd

An announcement on Rotated Grid Super Sampling, which reads: "The first Pre-Release for 1.21.11 is out! We've introduced a new shader-based terrain texture filtering method called Rotated Grid Super Sampling. It looks slightly worse than Anisotropic Filtering, but should give the same results on all GPUs. AMD implementation of AF currently does not work well with our block texture atlas, so we have switched AMD GPUs to use RGSS instead on "Fabulous!" preset. Apart from that we changed the mipmap generation algorithm again to give us slightly better visuals. And we also fixed some bugs."

An announcement on Rotated Grid Super Sampling.

• 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.Template:Note
  • "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).

Minecraft:Splash

• Added "Music by Minecraft:Hyper Potions!"

Changes

Items

Minecraft:Leather horse armor

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

Minecraft:Spears

• Changed the swap animation scale of all spears from Template:Cd to Template:Cd.Template:Source code ref
• 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 Minecraft:piglin-preferred weapon.
• Minecraft:Skeleton variants and Minecraft:drowned no longer pick them up.
• Minecraft:Zombified piglins can now charge with the spear and not just jab with it.
• Spears are now placed after Minecraft:swords in the Minecraft:Creative inventory.

Mobs

Minecraft:Camel Husk

• No longer sink in water while ridden by a player.

Minecraft:Nautilus and Minecraft: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 (Template:Cd).
• The Minecraft:nautilus shell drop is now affected by Minecraft:Looting.

Gameplay

Minecraft:Advancements

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

General

Minecraft:Data component format

• Template:Cd, Template:Cd and Template:Cd have been moved from Template:Cd and Template:Cd into a new component Template:Cd to allow all melee weapon types to use them.

Minecraft:Data pack

• The Minecraft:pack format version is now Template:Cd.

Minecraft:Resource pack

• The version is now Template:Cd.

Tags

• Entity Type Tags
  • Added Template:Cd to Template:Cd tag.
• Item Tags
  • Added Template:Cd to Template:Cd tag.

Minecraft:Textures

• Template:Cd section of Template:Cd files has a new Template:Cd 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 Template:Cd or lower than Template:Cd since the texture will become either fully opaque or fully transparent.
  • Default value for this field is Template:Cd, 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.
