21w43a is the seventh snapshot for Java Edition 1.18, released on October 27, 2021,[1] which adds the old world upgrading and fixes bugs.
Additions
World generation
Upgrading of old worlds
- Terrain from new chunks now blends with existing terrain from old chunks, preventing glitched borders from occurring.
- The old bedrock layer between Y=0 and Y=4 in old chunks gets replaced with deepslate.
- If there is bedrock at Y=0, lower places in old chunks are filled with deepslate.
- Caves do not generate below Y=0 in old chunks but lava lakes and geodes may generate.
- A new bedrock layer is placed at Y=-64.
- Worlds upgraded in this snapshot have these changes permanently applied.
General
- Added block tag
big_dripleaf_placeable.- Contains farmland and the #dirt and #small dripleaf placeable block tags.
- Big dripleaf can be placed on blocks in this tag.
Changes
Blocks
- Restricted big dripleaf placement to clay, coarse dirt, dirt, farmland, grass blocks, moss blocks, mycelium, podzol, and rooted dirt.
World generation
- Water levels change less often (slightly fewer underground waterfalls).
- Lava aquifers are slightly less common.
- Removed deep warm ocean biomes.
- Warm ocean biomes now generate in deep waters.
- Have been reshuffled again. Worlds don't look like as they did in previous snapshots.[2]
General

- "none" renamed to "Threaded".
- Changed some internal details of block and fluid ticking to improve save times.
Fixes
From released versions before 1.18
- MC-49010 – Cloning pressure plates or buttons whilst they're activated keeps them pressed forever.
- MC-131930 – Deep warm ocean generates without coral and sea pickles.
- MC-156616 – Badlands layers not generating properly.
- MC-217379 – Pufferfish don't spawn in deep warm ocean.
- MC-224205 – Cloned big dripleaves remain tilted forever when their tilt value is not equal to "none".
- MC-228745 – Big dripleafs can't be supported by farmland.
- MC-238073 – Decorators are independent of world seed.
From the 1.18 development versions
- MC-236615 – Priority updates setting has improper capitalization.
- MC-236624 – Deep warm oceans don't count towards the "Adventuring Time" advancement.
- MC-236970 – Badlands strata is covered by orange terracotta at Y=160 and above.
- MC-238939 – Stone can generate in the Nether.
