2.13 : by nnhomoli 03/27/2026 4:10:18 pmMarch 27 @ 8:10 pm UTC

Modrinth and Gitlab releases are now automated, so chances there's gonna be more small releases.

This beta 26.1 release brings a new size partitioning spec that is more performant to previous one.
This performance comes at a small loss, which in theory, should be almost impossible due to chunk interpolation.
