Java What changed in 1.13.1
Everything below is measured by comparing the game files of 1.13 with 1.13.1 — not copied from patch notes.
5 new blocks and items. Hover a slot for the name; click to open its page.
Mojang’s data generator did not produce the full registry report for one of these two builds, so this comparison covers blocks and items only. The other 0 registries could not be measured this far back — an empty section below means “not measurable”, not “nothing changed”.
