NeoForge 1.21.1 1.1.7-beta1

• Version: 1.1.7-beta1
• Target: NeoForge 1.21.1
• Type: Beta test build
• Release-preparation date: 2026-08-07
• Previous release baseline: 1.1.6-patch3

Release delta since the previous release

The first-parent delta contains 32 mainline commits after the previous release baseline, covering UI, compatibility, diagnostics, and durable-task behavior.

Player-visible changes

• Added and refined the global UI theme, semantic palette, theme editor/gallery, window motion, and area-destruction previews so dense screens expose state more clearly.
• Quick Build, batch storage, Smart Fill, Craft Terminal, remote GUI, and Create/Flywheel compatibility continue to align with the 1.1.7 mainline experience.
• Restored culling/preview state in cases where world or workflow transitions previously left it missing.
• If area destruction entered WAITING_RESOURCE because the tool was unavailable and the player starts a new single, chain, or replacement mining action, the old real area-destruction task is now cancelled instead of returning after UI timeout cleanup.
• The in-game AI guide now includes version boundaries and basic log analysis, and the opening Pilot notice names the 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.

• A new mining replacement cancels only non-terminal TaskType.MINING and area-destruction TaskType.DESTRUCTION tasks for the current player and dimension; PLACE, QUICK_BUILD, BLUEPRINT_BUILD, and unrelated tasks are unaffected.

• Cancellation goes through RtsTaskEngine.cancelWorkflowTask(...), writing CANCELLED, releasing tool leases/runtime state, preserving cursor/succeeded, writing a tombstone, and closing the visible workflow so restoreDurableProjection() cannot revive it.

• Normal WAITING_RESOURCE behavior is preserved; old work is cancelled only when the player explicitly starts a replacement action.

• This Beta should not overwrite important saves without a backup. For instability or severe regressions, return to 1.1.6-patch2 and provide client/server latest.log plus logs/rtsbuilding/ diagnostics.
