• What's LM 4?
  • LevelledMobs v4 is an upcoming revision of the plugin - the largest planned update in LM's history!
• Help for what?
  • We need your help testing LevelledMobs v4 snapshot builds. Test once or as many times as you want. Anything helps!
• Don't I need to have special skills to test?
  • Testing this plugin requires no special skills. Simply install it on your server and check if the plugin operates how it should be.
• Can't I contribute to LM in other forms?
  • LM is severely lacking any user contribution - currently all of it is done by the team.
  • Testing is very easy to do, and it helps us (and therefore every server owner) out tremendously.
  • Since every user is capable of being a great tester, we recommend it if you would like to help keep LevelledMobs free-of-charge.
• What's in it for me?
  • You'll make LevelledMobs updates come faster, and with far greater stability. This benefits every server that employs this software.
    
  • You'll receive permanent attribution for your kind contributions.
• How/when can I start testing?
  • Please ask @lokka30 on the Discord Server for information on this.
    
  • Snapshot builds are not yet available, but I will be sure to alert you when they are.
• What about LevelledMobs 3?
  • LM 3 is currently in a very stable state, such is why we never post messages like this to alert users who may be interested. If you would like to test LM 3 development/snapshot versions, please ask @lokka30 on the Discord Server for more information.

Full Changelog:
Thank you to @stumper66 and @Oathkeeper for maintaining LevelledMobs 3!
Thank you to everyone who has supported LevelledMobs so far - reviewers, donators, testers, contributors ( jeffry1928 in this update!), and all of the users who provide us with bug reports and suggestions. <3

Major Takeaways:

• New Chunk Kill Count system which limits the ability for players to farm levelled mobs their loot!
  • Thank you to jeffry1829 for contributing code for this system!
• Heaps of improvements and fixes. See below.

New:

• added chunk kill count feature to limit levelled drop farming
  • new settings in rules.yml: maximum-death-in-chunk-threshold, max-adjacent-chunks, chunk-max-cooldown-seconds, disable-vanilla-drops-on-chunk-max
  • new setting in settings.yml: exceed-kill-in-chunk-message
  • new option in customdrops.yml: use-chunk-kill-max
• added option in settings.yml use-adventure with default of true
• added new rule options under apply-settings: spawner-particles and spawner-particles-count. these are only used with LM spawners
• added fix for ConcurrentModificationException while checking getRule_CreatureNametagVisbility

Improvements:

• the difficulty presets have been renamed. they are now as follows: basic, average (default), advanced and extreme
• /lm rules reset command updated with the above preset names
• in the default rules.yml use-custom-item-drops-for-mobs is now set to true by default
• on server startup or running /lm reload and there is a parsing error in rules.yml, a more friendly message is displayed. a different message is also displayed to any op'd users
• improved summon attribute application rule
• updated internal dependency (bStats, Spigot, Paper)
• change custom names and lore to not have italics by default (Paper servers only)
• when summoning a mob with /lm summon it's spawn reason will now be LM_SUMMON for use in rules
• tweaked the zombie reinforcements attribute application
  • this patches a Minecraft bug causing zombie multiplication which has yet to be fixed by Microsoft
  • in rules.yml the ATTRIBUTE_ZOMBIE_SPAWN_REINFORCEMENTS setting is now by default 0 for all difficulties
  • zombies spawned with spawn reason REINFORCEMENTS will not get the ATTRIBUTE_ZOMBIE_SPAWN_REINFORCEMENTS attribute applied to them
• messages.yml, settings.yml and rules.yml file versions incremented

Fixes:

• fixed rule manager not respecting the random levelling strategy
• fixed summon command applying attributes based on rules maxLevel rather than the specified summoned level
• fixed issue with using custom drops with lore or custom names that use color codes. they will be more compatible with 3rd party plugins. applicable to Paper servers only
• when using a command command in a custom drop that uses PlaceHolder API placeholders, it will now pass the player argument that killed the mob rather than a null
• fixed /lm summon command spawning mobs near 1, 2, 1 location in the end
• /lm summon command will now level mobs as expected even if the world has not been enabled for levelled mobs
• fixed mobs spawning from LM spawners not using spawn reason LM_SPAWNER
• prevent custom drops from being applied to players
• fixed potenial missing player name in death message on Paper servers
• fixed special attributes not applying from custom rules
