You may have noticed today (June 17th) your Annihilus Launcher found an update. This is a pretty small update, so it is not considered 4.1. Here is the changelog:
• Iridescent Wings now show the correct Gold cost.
• Tyrael (Courts of Justice) items can no longer be obtained in Infernal Chests. The Lich King's items are still obtainable from the Infernal Chests, aside from Frostmourne, which must be obtained from The Lich King himself.
• Runes are back on the Gold Vendor, as it has been a week since the ladder reset.
• Added new unique Mirrored Boots that can drop anywhere in Hell from monsters that drop Item Level 80 or higher.
• Last Wish and Chaos Runewords now have the correct stats. If you have one of these contact me or @acyroma and we will give you an Orb of Alchemy to reroll it.
• Uldyssian now has 250 Physical Resistance and 175 Lightning Resistance. Both were drastically increased.
• You can no longer use Orb of Transmogrification on Key to Cthulhu's Lair.
