What I've found so far.
Nice new inventory system +1
Jungle rose is gone. 0
lovey new Corruption music. +1
Damage variance. +1
Healing when out of combat, further making the Nurse a useless piece of stuff. -1
The Ball of Light is now extremely slow and barely makes any light, further making IT a piece of stuff. -5
Molten Armor nerf'd a bit. -1
Necro Armor has removed speed bonus -1
Status effects like poison. You should've seen the look on my face when my Blade of Grass poisoned an enemy. +2
Lava Slime no longer makes lava, further making it a useless piece of stuff like all the other unoriginal slime colors. -1
Potion Sickness, not a big deal anyway 0
A slight sound-shifting thing added like in Minecraft 0
Mud and Ash no longer fall, making everything way too easy and making them not only useless, but boring -2
Tons of new decorative items +5
My rating for this update so far: -1
Edit: I read the wiki.
