Java What changed in 18w03b
Everything below is measured by comparing the game files of 18w03a with 18w03b — not copied from patch notes.
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”.
Development cycle
