LevelZ+ 2.1.0

A major progression and multiplayer update for Minecraft 1.20.1 / Fabric.

Multiplayer LevelZ XP

• Added contributor-aware LevelZ combat XP for LevelZ's independent XP system.
• Every recent player who contributed to a mob kill receives the full configured LevelZ XP reward instead of competing for the killing blow.
• Contribution persists through later environmental deaths such as fire or fall damage for the configured timeout window.
• Supports attribution from direct player damage, projectile owners, TNT owners and tamed entities.
• Ender Dragon progression remains on LevelZ's native dragon XP path.
• Spawner mobs remain excluded when spawnerMobXP=false.

Default combat reward:

normal mob XP × 1.0 + 10% of the mob's maximum health

The contributor reward percentage, timeout, mob-XP multiplier and health contribution are configurable.

Actually Harvest

• Added optional Actually Harvest 1.1.4.0 integration.
• Successful right-click crop harvests can grant independent LevelZ XP.
• Actually Harvest's normal Minecraft XP remains unchanged and separate.

Independent XP

• Designed for LevelZ's useIndependentExp=true mode.
• Normal Minecraft XP remains available for enchanting, Runic Attunement and other vanilla-XP systems.
• LevelZ+'s existing Luck XP bonus continues to affect ordinary Minecraft XP only and does not multiply LevelZ progression XP.

For Path of the Ascended, the intended LevelZ settings are:

• useIndependentExp=true
• mobXPMultiplier=0.0
• spawnerMobXP=false

Config migration

Existing config/levelz_plus.properties files are now upgraded automatically and non-destructively.

• Existing user values are preserved.
• Existing comments are preserved.
• Only missing 2.1.0 settings are appended.
• The new combat XP and Actually Harvest options are added with safe defaults.
• Fresh installations already generate the complete 2.1.0 configuration.

No manual deletion or regeneration of levelz_plus.properties is required.

Java compatibility

• Built entirely for Java 17.
• Fixes the development-build issue where two shared-XP classes were accidentally compiled for Java 21.
• Final release contains no Java 21 bytecode.

Maintenance fixes included

2.1.0 also includes the previously unreleased 2.0.2 maintenance work, including Small Ships alignment, LevelZ 1.4.13 targeting, Tom's Storage and Better Combat startup fixes, safer temporary compatibility contexts, and recovered-source cleanup.

Compatibility

• Minecraft 1.20.1
• Fabric
• Java 17+
• LevelZ 1.4.13
• Actually Harvest integration is optional

Existing LevelZ skill/stat balance is otherwise unchanged.
