I strongly advise you to make a backup of your "world" before doing this update
Update v0.4.2 :
Rework: - Added reworks to slimes
New: - Honey Slimes — spawn when a slime breeds in a birch forest, badlands, or on top of a honeycomb block
New: - Dispenser Slimes — size 3 slimes with a dispenser lodged inside them; they occasionally stop to shoot arrows at their targets. Arrows will inherit any fire or status effects the slime is under
Change: - Ranged mobs using bows (e.g. skeletons) will no longer all shoot at the same time when targeting the same entity within 15 blocks of each other — others will wait before drawing their bow
Fix: - Fixed warden's boss health bar being visible to all players on the server instead of only those within a 128 block radius
Fix: - Fixed wardens still displaying defeat text when the config option for it was disabled
Change: - Guardians now get staggered when a projectile hits their eye while attacking; they will also explode if staggered while the beam is yellow
