Official Changelog

English

This update brings Forge 1.20.1 fully in line with the new RTS plugin, blueprint, area-tool, and interaction systems, with a strong focus on large-modpack stability and usability. If you experience serious instability, returning to 1.1.2 is highly recommended.

New RTS Plugin & Progression System

• Progression Rework: Replaced the legacy skill tree with the installable RTS plugin system. Existing saves will automatically migrate unlocked abilities and grant corresponding plugin items.
• Team Sync & Sharing: Added team-shared plugin progress, installer-owned removal rights, manual state refreshing, and team name visualization.
• UI & Dependencies: Added concise feature tooltips to plugin items; holding Ctrl displays their detailed installation dependency paths.
• Claim Integration: Added full compatibility with FTB Teams and OpenPAC party and claim-protection boundaries, preventing RTS operations from bypassing claims.

Range Hiding & Area Tool Upgrades

• Range Hiding Feature: Ported "Range Hiding" (formerly Range Culling), allowing players to freely create, select, move, and edit hiding boxes in 3D space with six-direction handles.
• Rendering & Compatibility: Fixed ray penetration, block-entity rendering issues, and resolved compatibility issues with the Embeddium 0.3.31 entry-point.
• Expanded Geometry Shapes: Added spheres, cylinders, circles, walls, planes, lines, and boxes to both Quick Build and Area Destroy operations.
• Advanced Range Editing: Added Advanced Area Mode, allowing shape editing via draggable or scrollwheel-adjustable six-direction handles during preview.
• Smooth Nudge Controls: Unified smooth selection animation scaling and added micro-nudging support via arrow keys and Page Up / Page Down.
• Vertical Shapes: Added vertical circles and cylinders, enabling editing for complex shapes like ellipses, ellipsoids, and elliptic cylinders.
• Server Configurations: Added server-side configurable limits for area destruction, including maximum width, length, height, overall volume, target block count, and block processing limits per tick.

Fortified Blueprint System

• Unified Capture UI: Blueprint capture now utilizes the same smooth selection box and intuitive six-direction handle system.
• Data Sanitization: Hardened blueprint NBT, block-entity, and material substitution validation in survival mode to prevent cheating or illegal item duplication.
• Improved BG Support: Enhanced compatibility with Building Gadgets, improving blueprint import, rotation, material resolution, and resuming interrupted placements.

Interaction & Configurable Feedback

• Audio Limiter System: Added configurable RTS placement and breaking sounds. Added options to disable breaking sounds and cap audio cues per tick (excessive sounds are safely discarded to avoid delayed playback loops).
• Separate Sensitivities: Added four independent slider sensitivities for screen panning (Middle Click), view rotation (Right Click), keyboard camera movement, and scrollwheel zooming.
• Right-Click Priorities: Corrected standard right-click block interaction and Shift + Right-Click forced block placement priorities.
• Linked Placement Fix: Fixed issues where selecting certain blocks from linked storage failed to execute single or area placements.
• Creative Flow Improvements: Creative area building now bypasses material checks completely, allowing large-scale build tasks to proceed continuously.
• Smart Pick Block: Pick-block actions now prioritize items in the player's hotbar or inventory before extracting from remote storage.
• Instant Destruction: Area destruction now starts instantly without waiting for an unnecessary seed-mining phase.

Large Modpack Optimizations

• Search Caching: Cached creative search queries to significantly reduce typing and placement lag in large modpack environments.
• Recipe Routing: Fixed JEI recipe transfer availability and vanilla crafting-table routing issues.
• Storage Mod Integration: Improved compatibility and reliability for AE2, Refined Storage, Beyond Dimensions, Integrated Dynamics, and multi-storage setups.
• Texture Updates: Updated range-hiding, standard plugin, and field-deployment textures.
