Release Notes - Version 2.1.0

A feature and compatibility release adding support for Minecraft 26.3, expanding multi-geometry splatter rendering across diverse surfaces, enhancing rendering performance, and introducing an end-to-end automated combat smoke testing framework.

Highlights

• Minecraft 26.3 Compatibility:

  • Full support for Minecraft 26.3 on Fabric with updated mappings and runtime hooks.
  • Accommodates Mojang's internal entity class hierarchy refactors (Enderman) and interaction animations.
  • (Note: NeoForge builds for 26.3 will be released as soon as the upstream NeoForge decompilation pipeline stabilizes).

• Multi-Block Surface Splatter Enhancements:

  • Enhanced and hardened decal projection across non-standard block surfaces including chests, slabs, stairs, snow layers, and snow blocks.
  • Decals dynamically mesh and conform to half-slabs and complex bounding boxes without clipping or floating.
  • Thread-safe chunk marking and optimized decal mesh generation prevent frame drops or stutter during intense combat.

• Performance & Canvas Engine Optimizations:

  • Streamlined CanvasMesher quad generation and ClientCanvasStore caching.
  • Improved dirty-chunk scheduling and faster spatial key lookups.
  • Pixel-by-pixel erosion algorithm smoothly dissolves blood puddles with minimal CPU and GPU overhead.

• Automated Combat Smoke Test Suite:

  • Integrated a headless in-game combat test harness across all supported versions (1.21.1 through 26.3).
  • Automatically simulates player combat against live mobs to continuously verify particle flight, collision, and real-time decal projection.
