I suggest checking the Github for the various changes, I have done a bunch of those a while ago actually and was too tired to properly remember everything I had done.

2.1.8

• Added Chinese translation by XunYiShiny
  
• New data sent to customDamage functions (HP, handPush, footStomp)
  
• New data tag for zombies: jawStabImmune, canCrawlUnderVehicles

• Data tag for zombies: hitTime replacing resetHitTime
  
• Health was weird as a value before, same for damage received and now it should be more fitting ? (damage is divided by 10 before being applied to zombie health)
  
• Optimizations: less calls to server
  
• Changed call to update health for clients and on server, only the owner of the zombie (client handling the zombie) calls for a sync
  
• Cleaned up command functions, changed some names and variable names

• Another potential fix to zombies with high health going stale (help me)
  
• Custom health zombies not having a death animations (THIS MIGHT CAUSE IMMORTAL ZOMBIES, I NEED CONFIRMATION IF IT HAPPENS OR NOT)

2.1.7

• Optimization: remove ZombRand and replace with Random Java library which is a bit more efficient
  
• ZomboidForge.seededRand is more efficient than ZomboidForge.ZombSeedRand (less getters) tho requires basically the same data
  
• Code clarifications

• Potentially a new fix to high HP ZTypes going stale in MP. Having a too high difference of HP client and server side makes the zombie go stale, this patch tries to tackle this problem and finally fix stale zombies

2.1.6

• Fixed the new avoiding damage method causing zombies to pass other zombies their damage attribute when IsoZombie are recycled

2.1.5

• Fixed checking if zombie is reanimated to skip custom ZType for it
  
• Reworked checking for ZombieIsValid as it did not work properly and optimized it quite a bit. If you want to add your own check you can simply make a decoration of the function

2.1.4

• New data for onHit_zombieAttacking: attackOutcome (zombie:getVariableString("AttackOutcome"))
  
• New data for onHit_zombie2player: attackOutcome, hitReaction (target:getHitReaction())

• onHit_zombieAttacking now take table argument with corresponding data
  
• onHit_zombie2player now take table argument with corresponding data

• shouldIgnoreStagger should work better, now set zombie to avoid damage (which avoids staggers), and forces custom handling of damage to zombie. setIgnoreStaggerBack did not work at all (classic PZ am I right)
  
• shouldAvoidDamage now uses setNoDamage meaning it no longer uses setAvoidDamage and doesn't force anti stagger to the zombie

With the files it's better o7

2.1.3

• Data input of damage functions now taking tables

• Potential fix to disappearing zombies in MP when setting their HP server side too high (setting HP to 10 server side)

2.1.2

• Setting Mod Options ticks for nametag too high throwing errors

2.1.1

• New behavior tag: onHit_zombieAttacking. If `zombie` attacks `target`, even when `target` does have `hitReaction`.

2.1.0

• Optimizations everywhere
  
• Changed more functions to take table base argument (DamageZombie, ZombieAgro)
  
• New tool: ZomboidForge.ZombSeedRand. Takes a table base argument, 2 arguments or 3 arguments (refer to function annotations until doc is finished)
  
• Replaced seededRand (now deprecated) with ZomboidForge.ZombSeedRand
  
• New server2clients and client2server command: PathToSound. Syncs a zombie to path towards a sound for every clients
  
• Updated health update server side to make zombie a corpse (could improve syncing)
  
• Reorganized ZomboidForge_combat to have less function calls. Will improve performances but reduce the ability for custom patch to functions

• Damage from fire being too high, now you can set damage from fire with a new tag: fireKillRate. Should be a number, default from game is 0.0038
  
• Agro functions not running when a zombie is agro, should properly run now
  
• Removed commented prints from ATRO patched function, just for my mental health
  
• RemoveEmitters clientside command receiver annotation
