Slimefun Legacy 4.1.40 — Performance & Stability

Slimefun Legacy 4.1.40 is the stable production baseline for the current Legacy line, focused on smoother runtime performance, better diagnostics, and keeping established Slimefun behavior intact on modern servers.

⚡ Resonance Beacon performance

  • Player beacon potion effects now last 30 seconds and are refreshed only when roughly 15 seconds remain, instead of being reapplied every one-second beacon pulse.
  • Expensive furnace/spawner tile-entity discovery is cached for 15 seconds while boosts continue to operate from live block states on the normal gameplay cadence.
  • Reuses the same loaded-chunk footprint across beacon effect families instead of rebuilding it repeatedly during one pulse.
  • Resonance Beacons receive deterministic startup offsets so multiple loaded beacons do not synchronize their expensive work onto the same tick.
  • Player-state cleanup now runs when a beacon actually transitions from powered to unpowered instead of repeatedly rescanning the same area.
  • Powered beam rendering is bounded to prevent particle dispatch cost from scaling excessively with world height.
  • Existing Gravity Well, furnace, spawner, crop, XP, repair, flight, and other beacon behavior remains active without reducing the normal gameplay pulse rate.

⏱️ Diagnostics and server-owner tooling

  • /sf tick top remains available for profiling high-cost Slimefun machines.
  • Hotspot reports include actionable machine coordinates so expensive chunks can be located quickly.
  • Existing ticker freeze, inspection, circuit-breaker, and compatibility diagnostics remain intact.

🛡️ Stability and compatibility

  • Paper 26.2 is the primary supported platform.
  • Purpur 26.2 is supported.
  • Folia 26.2 remains experimental.
  • Paper/Purpur 1.21.11 compatibility checks are retained.
  • Built with Java 25 and verified to a Java 21 bytecode target.
  • Existing Slimefun item IDs, saved-world data, machine behavior, and addon-facing compatibility remain the priority.

📦 Release asset

  • Slimefun-Legacy4.1.40.jar

4.1.40 is intended to be the stable baseline for production servers. Future 4.1.x updates can focus on targeted maintenance, compatibility, and measured performance improvements without requiring disruptive migrations.
