Changelog for Minecraft 1.21.1

All notable changes to this project will be documented in this file.

1.21.1-1.9.2 - 2025-11-21 15:53:26

Added

• • Add translations through Crowdin (#350)

Changed

• Optimize predicate-based transfer using slotless index

By default, predicate-based aspects used the slot-based index to be able to handle cases such as #271. Since slot-based transfer can be a lot slower than slotless transfer, this is not great. Since the use case of #271 is quite exotic, the slot-based behaviour has been hidden behind an aspect property, while the predicate-based aspects will now always use the more performant slotless index by default.
