Chunkstone 1.8.0

Chunkstone 1.8.0

Chunkstone 1.8.0 adds selective Bedrock backup restoration. You can now restore
specific map-selected chunks to their original coordinates without rolling back
the rest of the world. All world processing remains local.

Highlights

• Restore map-selected chunks from a timestamped Chunkstone database backup.
• Reuse red map selections for both targeted pruning and targeted restoration.
• Replace regenerated or partial live chunk records with the older snapshot.
• Restore modern chunk actor records while avoiding duplicate actors that have
  moved to chunks outside the selected area.
• Keep the selected source backup unchanged by reading a protected working copy.
• Create a new automatic undo backup before modifying the live database.
• Report chunks missing from the chosen backup and records that were intentionally
  preserved instead of silently treating a partial operation as complete.

Warning

Use only a backup from the same world. Close Minecraft and other world editors,
keep an independent tested backup, and test the result before replacing a
production or Realm world. Selective restore operates on complete 16 by 16
chunks; it does not restore arbitrary individual blocks.

Validation

• All 23 automated tests passed for the release candidate.
• Source and packaged native application smoke tests passed.
• The installer reports file and product version 1.8.0.
• Installer size: 104,615,748 bytes.

Current limitations

• Windows x64 only.
• Selective restore supports Bedrock LevelDB worlds and whole chunks.
• Existing backups do not contain a cryptographic world identity; choose only a
  backup belonging to the loaded world.
• Actors already moved outside the restored selection remain at their current
  location to avoid duplicate entity identifiers.
• Very large backups require additional temporary disk space while the protected
  working copy is prepared.

Chunkstone 1.7.0

Chunkstone 1.7.0

Chunkstone 1.7.0 is the first official native Windows x64 release: a local desktop toolkit for mapping, pruning, repairing, optimizing, converting, inspecting, and publishing Minecraft worlds.

Choose a download

• Chunkstone-Setup-1.7.0-x64.exe - recommended installer with update detection, Start Menu integration, optional desktop shortcut, and uninstaller.
• Chunkstone-1.7.0-Portable-x64.zip - portable build; extract the entire archive before starting Chunkstone.exe.
• SHA256SUMS.txt - official checksums for both packages.

Warning

Close Minecraft and other world editors, work on a copy, and maintain an independent tested backup. Pruning, repair, conversion, record deletion, and NBT editing can permanently change a world.

Highlights

• View Bedrock terrain through a viewport-driven map with coordinate navigation, hover details, grids, overlays, and closer block detail.
• Draw, move, resize, save, reload, and remove protected or explicit-prune regions.
• Prune outside protected regions or remove only selected chunks using modal progress and backup workflows.
• Scan supported chunk payloads without modifying them, display exact corruption reasons, and remove confirmed malformed chunks for Minecraft regeneration.
• Browse supported Bedrock NBT, preview saved maps and structures, export .mcstructure, and delete selected records after backup.
• Track locally observed player NBT changes and notify after a configurable 30-day threshold.
• Perform best-effort Java and Bedrock conversion through the bundled local Chunker runtime.
• Preview and publish self-contained offline web maps with dimensions, crop bounds, grids, markers, overlays, presets, and ZIP output.

Audited runtime

This release uses nbtlib and Chunkstone's first-party adapter over the vendored BSD LevelDB code. The packaged tree was checked to ensure the previously restricted Amulet runtime is not present. Redistributed license texts are included in both packages.
