  (Neutrals Hero can be picked by either Scourge or Sentinel)
  
• All Razor skill is remade, except for his Chain Lightning
  
• Viper 2nd skill was remade, replace Frenzy with Nethertoxin (passive, give additional damage depends on enemy's health)

And 2 new heroes, Tauren Chieftain (Sentinel Strength) and Bat Rider (Neutral Intelligence). Bat Rider is old hero and appears in previous maps on Fun Tavern. You can type -fun for game modes for activing the Fun Tavern (you can try it in v6.58 or v6.59).
Not only that, there're 2 new items too! The items and their recipes:

• Magic Wand

Magic Wand is Magic Stick's upgrade, has Energy Charge to restore a bit of hero's health and mana. And Force Staff, is awesome item! The Force ability is like SpiritBreaker's passive skill, Greater Bash!
Unfortunately, it's still beta version and not official releases. But beta version is not bad for a try.
