Differences are computed from the extracted registries by ID, so a renamed entry shows as one removed and one added. Registries that did not exist in one of the versions are left out of the comparison.
Pick two versions and this tool lists every item, block, mob, enchantment, effect, biome, structure, painting and damage type that was added or removed between them, straight from the game's registries. It is the fastest way to see exactly what an update introduced without reading through full patch notes.
Each registry is compared by internal ID, so the results are exact: if a block exists in the newer version but not the older one, it is added; if it existed before and is gone, it is removed. A rename shows up as both, which makes reorganisations easy to spot.
Categories are sorted with the biggest changes first, so the headline additions of an update are right at the top. Expand any registry to see the full list of names.
The tool covers versions from 1.14 up to the latest snapshot. Because the data is the real extracted registry rather than a summary, it catches the small additions that patch notes sometimes skip, like a new variant block, a new damage type or a quietly added painting.
Older versions have fewer registries, since some categories did not exist yet. When a registry is missing from one of your two versions, the tool leaves it out of the comparison rather than reporting an entire category as new.
Pick a From version and a To version at the top of the tool. It loads the extracted registries for both and lists every item, block, mob, enchantment, effect, biome, structure, painting and damage type that was added or removed between them. The categories with the most changes are shown first so the big additions are easy to spot.
From the game's own registries, extracted per version into datasets. The tool compares the lists of IDs in each registry between your two chosen versions, so the additions and removals reflect what is actually in the game files rather than a hand-written changelog that might miss things.
Because the comparison is by internal ID. When the game renames an ID, the old ID disappears and a new one takes its place, so it appears once under removed and once under added. This is common around big updates that reorganise or rename content, and it is a useful signal that a rename happened.
Every version with an extracted dataset, ranging from 1.14 up to the latest snapshot. Older versions have fewer registries, since some categories such as damage types and the current biome format did not exist yet. The tool automatically skips any registry that is missing from one of the two versions you choose.
The comparison focuses on what was added and removed in each registry, which is the clearest signal of new content between versions. Tweaks to an existing item or mob's numbers are not listed here; for those, the individual calculator and reference tools show the current values for a chosen version.
