World Stripper

6.0.0 (Minecraft 26.3 - Fabric, NeoForge)

First release for Minecraft 26.3, with everything from 6.0.0 for 1.21 below. Forge is no longer built for 26.x. On 26.3 the strip/dress benchmark gives the same results as on 1.21 (r=24: strip ~160 ms, r=64: ~0.7 s on the server thread), and Fabric and NeoForge produce identical stripped worlds.

6.0.0 (Minecraft 1.21 / 1.21.1 - Fabric, NeoForge, Forge)

Faster stripping

Measured on a dedicated server, seed worldstripper, default strip list, Y -64..256 (time on the server thread; lighting continues on the light thread):

• The strip box is walked one chunk section at a time; sections whose palette holds nothing strippable are skipped.
• Blocks are written straight into the chunk sections (heightmaps, lighting, block entities, POIs and client updates are still handled).
• Light checks go to the light engine in one batch per section.
• Undo data is a compact palette copy per section instead of a map entry per block.

Fixes

• Dedicated servers: pressing Page Up / Page Down no longer crashes the server (#26).
• Forge (1.21): client-only event handlers are no longer loaded on dedicated servers (#26).
• The mod's network channel is optional: a client with World Stripper can join servers without it, and vice versa (#26).
• Keybinds have readable names again under "World Stripper" in Controls (#31).
• New /worldstripper strip [radius] and /worldstripper dress [radius] commands (#31).
• Mod icon is back (#33).
• Dressing restores the stripped blocks exactly: gravel and sand no longer fall into caves, fluids no longer start flowing.
• Undo data is kept per dimension and cleared when the server stops (dressing in another dimension or world used to paste the wrong blocks).
• /worldstripper edit works (it always failed with "No such argument").
• Default strip list: dirt_path instead of the old grass_path, removed the non-existent flowing_water/flowing_lava and a duplicate, added mangrove, cherry and azalea logs/leaves. Existing strippables.json files are not changed.
• No more empty worldstripper folder in the game directory.
• Errors while reading/writing the config are logged with their stack trace.

Notes

• With the default block-update settings, mobs that are already pathing through the stripped area don't re-plan their path immediately.
