Major Features & Support

• Minecraft 1.21.10 & 1.21.11 Support: Fully implemented support for the latest Minecraft versions, including support for new gliding behaviors, nautilus movement, tick-based world borders, camel variants, and updated block effects. (by @Cyramek, @Axionize)
• PostgreSQL Support: Added native support for PostgreSQL as a database backend for storing logs and player history. (by @NgLoader in #2368)
• Advanced Discord Webhooks:
  • Added support for Discord Forum Channels. (by @NgLoader in #2380)
  • Placeholders, custom domains, and markdown parsing for webhooks have been vastly improved. (by @Axionize in #2518)
  • Added a new /grim testwebhook command to easily verify your configuration. (by @ManInMyVan)

💻API Updates (v1.2.0 - v1.2.4.0)

This update contains numerous developer experience improvements and bug fixes for the Grim API.

• Simplified EventBus Registration: Developers no longer need to manually construct a GrimPlugin instance to use the EventBus. Platform-specific resolvers automatically determine the context (e.g., passing this from a Bukkit Plugin class or Fabric Mod Initializer).
• Fixed Reflected Listeners: Fixed a critical bug causing ClassCastException for listeners registered via registerAnnotatedListeners.
• New Methods: Added a method exposing the int block type from CompensatedWorld. (by @Cubicake in #2464)
• Note: Legacy API support has been temporarily added back to prevent breakage while developers migrate to the new standard.

⚡ Performance & Optimizations

• Message Optimization: Grim now sends fast chat messages directly at the packet level, bypassing the backend server to significantly improve performance. (by @Axionize in #2309)
• Math & Memory Improvements: Optimized bounding box calculations, Vector math (Vector3dm multiplier improvements), and implemented FastUtil map micro-optimizations to reduce garbage collection overhead.
• Cached Map Values: Cached map values to improve overall iteration performance. (by @Rothes in #2407)

🛠️ Check Improvements & Bug Fixes

• Movement & Reach Fixes:
  • Fixed a regression in Reach causing it to not flag certain clients from 1.15-1.20.1 and 1.21.5-1.21.8. (by @Axionize)
  • Fixed a Reach false positive involving Happy Ghasts on clients older than 1.21.6. (by @GreenedDev in #2352)
  • Fixed an exploit where players could reuse setback velocity to bypass movement checks. (by @SamB440 in #2450)
  • Fixed gliders not working correctly when placed in the offhand slot. (by @iLemon in #2397)
• Block & Interaction Fixes:
  • Fixed a FastBreak false positive that occurred when switching tools via a Shulker Box. (by @Ayouuuu in #2454)
  • Fixed collision and hitbox inaccuracies for Corals, Mushrooms, Fungus, Azalea, Beds, and Ceiling Wall Signs.
  • Patched false positives regarding Sculk Vein and Glow Lichen replacements.
• General Plugin Fixes:
  • Fixed a bug where using /grim spectate on a player in another dimension would incorrectly reset the spectator's gamemode to Survival. (by @GroupXyz2 in #2365)
  • Fixed a NullPointerException that occurred on Spigot servers using the late-bind option on versions older than 1.14.4. (by @uRyanxD in #2388)
  • Fixed Elytra packet abuse specifically targeting 1.8 servers. (by @ManInMyVan)
  • Fixed Folia breaking the getTPS() metric (temporary patch). (by @Axionize)
• Stable Checks: Elytra (A, B, C, F), PositionBreakB, and MultiActions (C, D) have been marked as stable.

⚙️ Platform & Under the Hood

• Fabric Enhancements: Switched to Mojmap for Fabric obfuscation mappings, refactored the Fabric implementation to make the Permissions API and Cloud optional dependencies, and added specific support for Fabric 1.21.11.
• Dependency Bumps: Updated PacketEvents, Cloud, and Shadow Gradle plugins to their latest versions to resolve underlying packet ordering and mapping issues.
• CI/CD Migration: Migrated GitHub Actions workflows to Tenki for faster and more reliable builds.
