Changes

Zeroes have been removed from item links. They now look like: |cff0070dd|Hitem:128955::::::::99:577::11::::|h[The Spider Queen's Veil]|h|r
The way nameplates are created has changed completely.
- New addon: Blizzard_Nameplates
- New events: NAME_PLATE_CREATED, NAME_PLATE_UNIT_ADDED, NAME_PLATE_UNIT_REMOVED
- Functions like GetNumNamePlateMotionTypes and GetNameplateFrames have been moved to a new C_Nameplates table.
  - C_NamePlate.GetNamePlateForUnit,
  - C_NamePlate.GetNamePlateSizes,
  - C_NamePlate.GetNamePlates,
  - C_NamePlate.GetNumNamePlateMotionTypes,
  - C_NamePlate.SetNamePlateSizes,
The Texture method Texture:SetTexture(R, G, B[, A]) no longer works properly in many cases. Use the new method Texture:SetColorTexture instead.
The Texture method Texture:SetTexCoord no longer works properly for values greater than 1. This was previously used for horizontal and (especially) vertical tiling. For now, use the optional parameters in the method Texture:SetTexture(texturePath[, horizTile[, vertTile]]) instead to tile textures. Alternatively, Texture:SetVertTile(<bool>) and Texture:SetHorizTile(<bool>) might be the intended replacements for this behavior.
The Texture method Texture:SetToFileData has been removed and is now handled by Texture:SetTexture instead.
GetSpellInfo(spellid) now returns fileID for its 3rd return instead if iconPath.
The deprecated animation method Alpha:SetChange has been removed. Use Alpha:SetFromAlpha and/or Alpha:SetToAlpha instead.
GetInboxItem now returns the itemID between name and itemTexture: name, itemID, itemTexture, count, quality, canUse = GetInboxItem(index, itemIndex)
GetSendMailItem now returns the itemID between name and itemTexture: name, itemID, itemTexture, count, quality = GetSendMailItem(sendMailIndex)
GetNumDungeonMapLevels now returns an array of level numbers. To get the count of levels, get the length of the returned array
GetMapLandmarkInfo now returns a type integer as its first return value, before name which used to be the first return value
Frame type Minimap are no longer creatable by CreateFrame and will be ignored in xml files for 3rd party addons.
GameTooltip:SetTradeSkillItem(tradeItemIndex[, reagentIndex]) replaced by GameTooltip:SetRecipeReagentItem(recipeID, reagentIndex).
GetQuestLogRewardSpell(rewardSpellIndex) requires rewardSpellIndex parameter now
GarrisonUI API have been updated and multiple of the C_Garrison.* now requires a LE_* filter and new return values have been added.
Some Mountjournal Functions got renamed
- C_MountJournal.GetMountInfo has been renamed to C_MountJournal.GetMountInfoByID
- C_MountJournal.GetMountInfoExtra has been renamed to C_MountJournal.GetMountInfoExtraByID
- C_MountJournal.Summon has been renamed to C_MountJournal.SummonByID
