Fabric 1.21.1 0.0.2

• Version: 0.0.2
• Target: Fabric 1.21.1
• Type: Early test build
• Release-preparation date: 2026-08-07
• Previous release baseline: 1.1.6-patch2-fabric-alpha.1

Release delta since the previous release

The Fabric first-parent delta contains 3 commits after the baseline: the 1.1.7 mainline experience port, area-destruction outlines/highlights, and the real cancellation fix for a resource-waiting task replaced by new mining.

Player-visible changes

• Synced area-destruction outline/highlight state and continued the 1.1.7 interaction experience on Fabric.
• After AREA_DESTROY enters WAITING_RESOURCE because the tool is unavailable, starting MINE_SINGLE, chain mining, or another replacement action now genuinely cancels the old area-destruction task; it cannot return after UI cleanup.
• The opening notice and in-game AI guide identify Fabric as its own line and show its rollback build.

Technical and compatibility notes

• The tutorial now covers Storage binding read/write versus extract-only access, Range binding, and UI theme changes. The in-game AI and local versioned appendices also document the client → network → server → task/persistence chain, client/server log boundaries, and trace-based analysis. Normal how-to answers stay brief; recent logs are used for bug diagnosis.

• Only non-terminal MINING and area-destruction DESTRUCTION tasks for the current player and dimension are cancelled; PLACE, QUICK_BUILD, and BLUEPRINT_BUILD remain unaffected.

• Cancellation preserves cursor/succeeded, writes CANCELLED and a tombstone, releases tool/runtime state, and closes the workflow; normal WAITING_RESOURCE remains resumable.

• This is an early Fabric test line. If unstable, return to 1.1.6-patch2-fabric-alpha.1; do not transfer NeoForge API or log conclusions directly to Fabric.
