26.2 Pre-Release 1 (known as 26.2-pre-1 in the launcher) is the first pre-release for Java Edition 26.2, released on May 26, 2026,^[1] which gives small sulfur cubes a unique model.

Telemetry

• Added server_session_id - a unique identifier shared by all players in a multiplayer session.

Potent sulfur

• The continuous geyser set-up now requires a source lava block to erupt.

Chicken

• Updated hurt and death sounds for the "picky" sound variant.

Sulfur cube

• Small sulfur cubes now have an updated model and texture.
• Small sulfur cubes now have sounds playing when being fed with slimeballs.
• Now has unique hit and push sounds for each archetype.

Sulfur caves

• Updated the fog color in the sulfur caves.
• Reduced the max growth length of the sulfur spikes.

/execute

• /execute on owner will now consider vexes as owned by their evoker.

/publish

• Rolled back the changes from previous version.

Data pack

• The pack format version is now 106.1.

Friends list

• No longer waits until the next presence update following the initial opening of the friends list to load player skins.
• Friends list width has been increased to fit longer usernames.
• "Manage online safety with your Microsoft account" text is no longer slightly offset to the left.
• "Microsoft account" link now plays the click sound when pressed.
• The "My profile name: " text now displays properly in right-to-left languages.

Identifiers

• Entries in the minecraft:sulfur_cube_archetype registry have a new field:
  • sound_settings - a field that contains various sound settings for the sulfur cube.
    • hit_sound - sound event that is played when the sulfur cube is hit while it has a block inside.
    • push_sound - sound event that is played when the sulfur cube is pushed while it has a block inside.
    • push_sound_impulse_threshold - float that specifies the smallest impulse required to trigger the push sound effect on the sulfur cube.
    • push_sound_cooldown - float that specifies the cooldown in seconds for the push sound effect.

Resource pack

• The version is now 88.0.

Server properties

• Added chat-spam-threshold-seconds and command-spam-threshold-seconds properties, separating the spam thresholds for chat vs commands.
  • Both thresholds are set to 10 by default, which was the existing threshold for combined command+chat spam.
  • These thresholds configure the mechanism that automatically kicks players for sending too many chat messages or commands.
  • The value describes how many seconds worth of spamming a player must do to get kicked, where each message a player sends increases the counter by 1 second.
  • The counter is decremented once per tick (equivalent to 1/20th of a second), and a player is kicked if their counter reaches the configured threshold.
  • Either threshold can be set to 0 to disable kicks for the associated type of spam.
  • Examples of message rates that would cause a kick, given the default threshold of 10:
    • Sending 11 messages in 1 second.
    • Sending 14 messages in 2 seconds.
    • Sending 21 messages in 10 seconds.

Sounds

• Removed sounds for Sulfur Cube:
  • entity.sulfur_cube.hit
  • entity.sulfur_cube.push

  • entity.sulfur_cube.regular.hit
  • entity.sulfur_cube.regular.push

  • This preset does not show up by default in the create world screen.

Friends list

• Displaying invites for or requesting to join online worlds has been removed.

Peer-to-Peer multiplayer
