Java Edition 26.1 Pre-Release 1

26.1 Pre-Release 1 (known as 26.1-pre-1 in the launcher) is the first pre-release for Java Edition 26.1, released on March 10, 2026,^[1] which updates the panorama and makes technical changes. This is the first pre-release released in 2026, and the first pre-release to be released with only an unobfuscated build.

Number providers

• Added minecraft:environment_attribute
  • Fetches and provides the value of an environment attribute (that can be represented as a number).
    • This provider requires a context with an origin position set as long as the environment attribute can vary positionally.
  • Format: object with fields:
    • attribute – environment attribute ID to fetch.
    • e.g. {type: 'environment_attribute', attribute: 'gameplay/sky_light_level'}

Predicates

• Added the minecraft:environment_attribute_check loot predicate.
  • Exactly matches the value of an environment attribute at a given position.
    • This predicate requires a context with an origin position set as long as the environment attribute can vary positionally.
  • Format: object with fields:
    • attribute – environment attribute ID to test
    • value – Exact value of the environment attribute to match
    • e.g. {condition: 'environment_attribute_check', attribute: 'gameplay/piglins_zombify', value: true}

Tags

• Added the #can_spawn_from_bone_meal configured feature tags.
  • Contains features that, when added in a biome, can be spawned when using bone meal in that biome.

/time

• Syntax:
  • /time [of <clock>] rate <rate> – sets the rate multiplier at which the clock should advance.
    • This only changes the rate at which the world clock and any timelines dependent on it advance their internal timers.
      • For example, in the case of the minecraft:overworld clock, the day/night cycle will pass quicker with a larger value, but actual game simulation will not speed up (as would happen with /tick rate).
    • A rate of 1 corresponds to normal speed.
    • rate is a float between 0 (exclusive) and 1000 (inclusive).

Data component format

• minecraft:provides_banner_patterns
  • The component now also accepts an ID or a list of IDs in addition to a tag.

• minecraft:blocks_attacks
  • The field bypassed_by now also accepts an ID or a list of IDs in addition to a tag.

• minecraft:damage_resistant
  • The field types now also accepts an ID or a list of IDs in addition to a tag.

Data pack

• The pack format version is now 101.0.
• The "Default Components" report generator no longer outputs files for entries without any components.

Items model definition

• minecraft:end_cube special model type
  • New special model type that renders a cube with the same texture effects as the end portal and the end gateway blocks.
    • Fields:
      • effect – texture effect to apply, one of: portal, gateway

Loot functions

• minecraft:set_instrument
  • The options field now also accepts an ID and a list of IDs in addition to a tag.

Panorama

• Updated the panorama to reflect Tiny Takeover.

Rendering

• End gateway and end portal should now look the same when rendered on a block display as they look when placed in world.

Resource pack

• The version is now 84.0.
• Updated textures for Pup to fix issues with overlapping textures.

Shaders

• The core/rendertype_translucent_moving_block shaders have been removed in favor of core/block.

Text component format

• minecraft:object
  • Added a new optional field named fallback that contains a text component to be used when object component itself can't be displayed (for example when printing messages in server logs or during narration).
  • Objects of type player (player heads) no longer can be used in server status messages (MotD).
    • All components of that type will be replaced by a fallback text.

World generation

• Flower features
  • Features spawned from Bone Meal are no longer restricted to the flower feature type, and instead controlled by the #can_spawn_from_bone_meal configured feature tag.
  • The flower, flower_no_bonemeal, and random_patch feature types have been removed.
    • Instead, patches can be expressed as a sequence of count and random_offset placement modifiers.

• Int Providers
  • Added the trapezoid int provider
    • Selects a random value with a trapezoid distribution, similar to the trapezoid float provider.
    • Format: object with fields:
      • min: integer, the minimum value to generate.
      • max: integer, the maximum value to generate.
      • plateau: integer, the width of the "plateau" of the distribution in which all values are equally likely to occur.
        • A value of 0 is equivalent to a triangle distribution.
        • A value of max-min is equivalent to a uniform distribution.
