2.2 2026-09-30 Beta Latest

Phase 1 — multi-version + full GUI

  • Multi-version builds: all 17 Minecraft releases (1.21 through 26.3) via version matrix — Mojang mappings for 1.21.x, bundled for 26.x
  • Command framework: parser with quoting/escaping, registry with namespace + trie prefix search, completion engine, middleware pipeline
  • Config validators: range, enum, TTL cache, diagnostics — invalid values rejected at write time
  • Performance engine: FrameTimeMonitor (240-slot ring buffer), real FPS / avg FPS / 1% low, CPU/memory dashboard
  • Accessibility: 6 features wired (color-blind filter, high contrast, UI scaling, screen reader, reduced motion, keyboard nav) with settings screen
  • HUD editor: drag-and-drop, snap-to-grid, grid overlay, right-click visibility toggle, JSON persistence
  • Keybind editor: click-to-rebind, conflict detection, per-row reset, persistence
  • Mod menu rewritten: category tabs, real-time search, feature card grid with toggles, expand for details
  • Settings screen rewritten: 7 sections (General, Performance, Visuals, HUD, Keybinds, Accessibility, About)
  • QoL: smooth zoom (2x/4x/8x scroll levels), animated freelook, fullbright modes, dynamic crosshair, waypoint distance colors
  • Mod wired to core command framework (CoreCommandBridge); 125 features across 16 categories
  • Every feature actually implemented — no dead toggles
Requires Java 21 for 1.21.x, Java 25 for 26.x
2.1 2026-09-28 Release

Stabilisation and launch fix

  • Fixed launch crash: glGetString called before OpenGL context existed — EXCEPTION_ACCESS_VIOLATION on every launch
  • Fixed mixin crash: MouseClickMixin declared CallbackInfoReturnable on a void method — entire mixin silently failed
  • Wired module-ai into the Gradle reactor — 221 tests now reachable
  • 3,800+ tests passing across all modules
Requires Java 21 — not 25. The mod's fabric.mod.json enforces this, but older JREs fail silently
Fixed: MemoryRenderer GL function pointer null on launch
0.1.0-dev 2026-07-21 Alpha

Early development build

  • Modular client with 50+ toggles
  • HUD suite, keybinds, mod menu
  • 16-version build matrix
Alpha — expect rough edges

Known: mixin descriptor warnings on some 1.21.x builds (silently skipped)
