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

Removals

• Glyph handling: CastGlyph, SetGlyph, GetGlyphInfo, etc.
• GetInventoryItemGems and GetContainerItemGems (but gem information is still apparently extractable from the itemString)
• GetQuestLogRewardTalents
• API regarding in-field visibility changes to helms and cloaks: ShowHelm, ShowCloak, ShowingHelm, ShowingCloak
• Functions regarding defunct stats Multistrike and Amplify
• Frame method: Frame:AllowAttributeChanges()
• Event UNIT_COMBO_POINTS (streamlined into UNIT_POWER)
• CVar floatingCombatTextComboPoints (streamlined into CVar floatingCombatTextEnergyGains)
• Model:GetModel() has been replaced by Model:GetModelFileID()
