LeanCore

LeanCore is server-side memory governor for Hytale. Unloads idle map regions, trims view radius under heap pressure, and learns which zones get revisited so it keeps the ones you actually use.

What's new

Changelog (1.7.2)

Added

  • Update notifications: on startup LeanCore checks the DurkzPRG mod page for a newer JAR and notifies operators or LeanCore admins once per session (clickable CurseForge project link). Opt out with checkForUpdates: false (default true)

Fixed

  • Lower allocation pressure in recurring runtime passes: dormancy ranking, world dispatch, and player behavior classification
  • Lower allocation pressure in policy updates: hot-radius application, dormancy refresh, behavior snapshots, and LITE policy logging
  • Reduce policy dispatch allocations by removing per-pass maps and player apply objects while keeping world tasks isolated
  • Remove recurring feature-snapshot allocations via direct player feature lookups and indexed world-batch loops

Notes

  • Drop-in from 1.7.1; LeanCore.json and learning state are kept
  • Existing configs without checkForUpdates keep the default true
