Been working on Destroyer before I started this update. I might post some teasers at some point, just not sure when.
Moving forward, most future updates will be for 1.4.4.

v0.4.0.0 published to Stable (1.4.3)

Additions

v0.3.0.1 published to Stable
Additions

• QB - Hives have a hint arrow to indicate to destroy them if QB has at least 80% HP
  
• WOF - Attacks no longer repeat until all available attacks have been done at least once

Changes

• EOW - Made boss send less unnecessary packets between server and client, hopefully the fight should be less laggy in multiplayer?
  
• EOW (buff) - Base contact damage on body and tail increased to 20 (13 & 11 -> 20)
  
• BOC (nerf) - P1 5 Watcher sweep in master mode now only occurs 20% of the time, making it more inline with how normal mode handles it
  
• QB (nerf) - Honey shots despawn 1 second quicker, hives and honey in same attack have more delay in master mode
  
• QB (nerf) - Lowered fire rate of stinger in gattling attack in master mode
  
• Skel (nerf) - Bone cap during the ring/bone hands lowered to 9 and homing bones now comply with the cap (originally 10 + homing bones ignored cap), there can be up to 8 regular bones while 1 slot is reserved for a homing bone

Bugfixes

Late christmas update oops

v0.3.0.0 published to Stable

Additions

• Added Wall of Flesh rework, there are too many changes to list, but major changes are listed below

WOF general reworks

• 2 phases, 6 attacks total
  
• Always moves at a constant speed and never accelerates, reducing the need to build long bridges
  
• Arena is enforced to prevent outrunning the wall and to build attacks around it
  
• Each part has an extra invisible health bar (700 HP) that decreases by simply dealing damage to it. Whenever it runs out, the part enters a stunned/dead state where it stops attacking momentarily. The part recovers after a couple of seconds, resetting back to 700 HP.
  
• If all 3 parts are stunned at the same time, bonus damage of around 1000 HP is dealt to WOF and their current attack prematurely ends.
  
• The mouth has a shorter recovery time due to some attacks solely requiring the mouth to work.

Changes

• Now playable in preview branch
  
• KS - Now only drops his crown on first teleport instead of every teleport
  
• BOC, Skel - Outer arena reach for debuffs/penalties increased
  
• Skel - Ring arena now inflicts withered weapon (-50% dmg) instead of cursed, obstructed now blinks instead of being constant
