v1.0.0

First public release.

Added

• 3D viewer for .nbt, .schem, .litematic and .mcstructure files, rendered with the
  real models and textures of your own Minecraft content pack (modded blocks included), with
  block entities, animated fluids and ~80 vanilla mobs drawn as their actual models.
• World viewer and editor — open a whole save (1.13+) with streamed chunks and LOD, minimap,
  dimensions, waypoints, find blocks/structures and a Y-slice. Editing is opt-in and gated by a
  safe write path: session lock, enforced backups, surgical chunk patching and atomic region
  writes. Place any build into the world (with terrain blend) or extract a region back out.
• AI structure generation from a prompt or reference image on your existing Claude or Codex
  subscription, through an emit → render → review loop, plus a composable build planner
  (structure / decoration / roof / basement / attic / yard / per-floor rooms) with live previews.
• Block editor — select, paint, move, mirror, rotate, extrude, replace and delete in the
  viewer, with magic select, percentage paint patterns, symmetry, undo/redo and versioned saves.
• Structure Diff, Re-theme, Materials and Beauty Render — compare any two builds or versions,
  swap palettes with blockstates preserved, roll a build up into a bill of materials, and export
  high-resolution PNGs or turntable WebMs.
• Mod workspace pipeline — render and generate with a mod's own blocks, export version-correct
  structures plus their worldgen JSON, auto-split oversized builds into jigsaw assemblies, install
  a ready-to-run datapack with Export to World, and round-trip through in-game Structure
  Blocks.
• Jigsaw Lab, Worldgen Studio, Structure Lint and the Worldgen Doctor — connector arrows and
  multi-seed simulation in 3D, validated forms over the four worldgen files with surgical writes,
  per-file linting, and a data-pack audit with one-click fixes.
• Version travel — upgrade a workspace to its target Minecraft version or downgrade copies to
  an older one, with every change and loss reported and originals never touched.
• Blockwright MCP server — drive builds from Claude Code or Claude Desktop over a local
  HTTP endpoint.
• Support for Minecraft releases through 26.2, an interface in English and Português
  (Brasil), themes, a structure library, auto-updates, and offline license activation.
