Minecraft 26.1 snapshot 2

07 Jan 2026 Original Changelog

This first snapshot of 2026 adds new baby mob models.

Mobs

Some mob bounding boxes have changed:

Mob	Width	Height	Eye Height
Adult Rabbit	0.4 → 0.49	0.5 → 0.6	0.425 → 0.63
Baby Rabbit	0.2 → 0.24	0.25 → 0.4	0.2125 → 0.44
Baby Chicken	0.2 → 0.3	0.35 → 0.4	0.2975 → 0.28

Rabbits

A rabbit jump now lasts 15 ticks, up from 10 ticks. Rabbits now jump higher and less far forward with each jump.

GameTest

Added padding (integer from 0-128, default 0) to the test instance definition. It expands the test bounding box by padding blocks in every direction around the test structure.
