What's new

2.5.0 (2026-05-23)

Highlights

  • Added per-item attack cooldown support for items such as maces and spears, closing #856.
  • Added default world modesets, including migration for existing configurations, to make configuration quicker and easier when you have lots of worlds.
  • Added build commit details to version output to make support reports and deployed builds easier to identify.

API and integrations

  • Added API controls for per-player module overrides and modesets, plus player state change events, documentation, and examples for integrations that need to react to combat-mode changes.
  • Validated bulk module override updates before applying them, avoiding partial or inconsistent per-player override state.

Compatibility

  • Improved attack-range support on Paper by detecting data component availability instead of relying on version assumptions.
  • Reworked compatibility checks and optional API fallbacks to use capability detection and safer version comparisons.

Fixes

  • Fixed mixed-mode combat handling so armour strength and shield blocking use the defender's modeset, while tool damage uses the attacker's modeset.
  • Fixed explosion defence applying the wrong modeset (#861).
  • Fixed no-knockback handling for MythicMobs damage (#860).
  • Fixed damage types with bypasses_cooldown incorrectly interacting with attack cooldown logic (#864).
  • Fixed stale stored world modesets being reused after world or configuration changes (#865).
