GUID overhaul:
The Globally Unique Identifier format has been completely redesigned, consider the following:

• Players: Player-[serverID]-[playerUID]
  • Example: Player-976-0002FD64
• Creatures: Creature-0-[serverID]-[instanceID]-[zoneUID]-[npcID]-[spawnUID]
  • Example: Creature-0-976-0-11-31146-000136DF91 (http-//www.wowhead.com/npc=31146)
• Pets: Pet-0-[serverID]-[instanceID]-[zoneUID]-[npcID]-[spawnUID]
  • Example: Pet-0-976-0-11-23258-000136DF91 (http-//www.wowhead.com/npc=23258)
• Object: GameObject-0-[serverID]-[instanceID]-[zoneUID]-[ID]-[spawnUID]
  • Example: GameObject-0-976-0-11-1733-000136DF91 (http-//www.wowhead.com/object=1733)
• Vehicles: Vehicle-0-[serverID]-[instanceID]-[zoneUID]-[npcID]-[spawnUID]
  • Example: Vehicle-0-976-0-11-27881-000136DF91 (http-//www.wowhead.com/npc=27881)
• Vignettes: Vignette-0-[serverID]-[instanceID]-[unknown]-[0]-[spawnUID]
  • Example: Vignette-0-970-1116-7-0-0017CAE465 (http-//beta.wowhead.com/spell=163108)

As of build 18888, the format has changed from using colons to hyphens for splitting each value.



Item hyperlink changes:
Item hyperlinks have been updated to support bonusIDs and instanceDifficultyID.
Also, with the removal of the reforge system, reforgeID is gone:

• Old:
  • itemID:enchant:gem1:gem2:gem3:gem4:suffixID:uniqueID:level:reforgeID:upgradeID
• New:
  • itemID:enchant:gem1:gem2:gem3:gem4:suffixID:uniqueID:level:upgradeId:instanceDifficultyID:numBonusIDs:bonusID1:bonusID2:...

They can be used for storing random suffixes (e.g. "of the Fireflash"), random bonuses (e.g. bonusID 40 is +Avoidance), raid types (see below), dungeon typing, random quest upgrades (see below for epic/rare), crafting upgrades (e.g. bonusID 526 is "Expert") and others.

Some examples of bonusIDs:

• 448 - Warforged, +6 itemlevel
• 449 - Heroic, +13 itemlevel
• 450 - Mythic, +26 itemlevel
• 451 - LFR, -12 itemlevel
• 15 - Epic, +10 itemlevel
• 171 - Rare, +5 itemlevel

BonusIDs can adjust itemlevels, modify stats, change itemquality, add item titles, appends words to item names, add sockets, adjust appearance, adjust required equip level, and possibly many more.


World markers:
We now have 8 world markers (up from 5), the new colors are as follows:

• Orange (represented by the circle raidicon)
• Silver (represented by the moon raidicon)
• White (represented by the skull raidicon)
