Hi everyone, I'd like to share some notable API changes in Legion. All of them have been tested in current alpha realm and I'm pretty sure you guys may in need of them. :-)

animationGroup:SetChange() has been removed
This one occurs in such circustance:

Lua Code:

local flash = item:CreateAnimationGroup()
for i = 1, 3 do
    local fade = flash:CreateAnimation('Alpha')
    fade:SetDuration(.2)
    fade:SetChange(-.8)
    fade:SetOrder(i * 2)
 
 
    local fade = flash:CreateAnimation('Alpha')
    fade:SetDuration(.3)
    fade:SetChange(.8)
    fade:SetOrder(i * 2 + 1)
end

GetAuctionItemClasses() has been removed
This one occurs in such circustance:
Lua Code:
```
local QUEST = select(10, GetAuctionItemClasses())
```
In fact, QUEST == "Quest" in enUS, just a string indicating quest items.
SetTradeSkillItem() has been removed
This one occurs in such circustance:
Lua Code:
```
hooksecurefunc(tooltip, 'SetTradeSkillItem', OnTradeSkill)
```

UnitIsTapped()/UnitIsTappedByPlayer() has been removed
This one occurs in such circustance:

Lua Code:

if not isName and (dead or (UnitIsTapped(unit) and not UnitIsTappedByPlayer(unit))) then
    return 0.5, 0.5, 0.5

UnitPowerMax()/UnitPower() should specify power type now, not an optional one
We use this code now:
Lua Code:
```
local value = UnitPowerMax(unit)
```
In Legion we should do something like this:
Lua Code:
```
local value = UnitPowerMax(unit, UnitPowerType(unit))
```
texture:SetTexture(r, g, b, a) changes into texture:SetColorTexture(r, g, b, a)
texture:SetTexture(texture_path) is working as well, but Blizzard creates as new SetColorTexture to cover texture:SetTexture(r, g, b, a) function.
In Legion if you want to specify texture by a texture path, use SetTexure. For RGBA value, use SetColorTexture instead.
item:125794:::::::::: is allowed now
For item link, we use something like "item:125794:0:0:0:0:0:0" before.
But in Legion, we can dismiss these zeros.
For user who wants to regex an item link, this is useful.
We can use texture:SetTexture(file_id) now, so GetSpellInfo will not return a texture path as the 3rd return value
We use this code to set an icon now:
Lua Code:
```
local _, _, icon = GetSpellInfo(spell_id)
texture:SetTexture(icon)
```
In Legion, that's easier:
Lua Code:
```
file_id = GetSpellTexture(spell_id)
texture:SetTexture(file_id)
```

Here is what I'm using in alpha realm:

I did some changes to these addons so they will work in alpha environment.
