Fixes
From released versions before 1.21
- MC-211096 – Entities in cobwebs clip through pistons.
- MC-278182 – Items glitch inside the piston head when pushed through powder snow or cobwebs.
From 1.21.9
- MC-301916 – The behavior of wind charges when colliding with certain blocks is different.
- MC-302321 – Chunks do not load while the player is being teleported.
- MC-302383 – Rooms with carpet on the floor cannot have maps in item frames placed on walls touching the floor.
- MC-302405 – Repeating (or chain) command block with any form of
/tp [player]doesn't constantly tp player to one spot. - Fixed an issue that caused entities on bubble columns to fly high up into the air.
Trivia
- This version has the same protocol version number as 25w42a. The two versions are not actually compatible; 1.21.10-rc1 throws a "Network Protocol Error" message when attempting to join a 25w42a world, and 25w42a crashes when attempting to join a 1.21.10-rc1 world.
