Blizzard implemented a relatively small patch that includes a new addition to the Pet Journal, cross-realm mail, and the Blizzard Store...that's accessible in-game! [source]
A Preview in the Journal
Treasure Goblin (pictured right) was added to the Pet Journal in this patch, however the pet itself is still not available at this time.
Those that purchase the Collector's Edition of Diablo III: Reaper of Souls will be lucky enough to finally get a hold of this evasive little goblin and add him to their collections while earning the achievement Collector's Edition: Treasure Goblin.
The release date hasn't been announced yet, so we'll have to wait a while longer for this pet.
Mailing Pet Items Cross-Realm
Have an alt on another server that's overflowing with pet bandages and treats that you wish you could use on characters on another server? Worry not because the cross-realm mail feature is now live!
Account-Bound items are now truly "account-bound," and players can mail these items between their characters even if they are located on different realms. These items include (but are not limited to):
To mail an Account-Bound item to another one of your characters, address it to "Player name-Server name." It's that easy!
In-Game Blizzard Store
Last but not least, the Battle.net Store can now be accessed while in-game. You can browse and purchase pets without ever straying from Azeroth! [source]
There's a new shop icon that will lead you to the in-game store's interface. Keep in mind prices may not be finalized and not all store options have been implemented yet.
Physical items, such as the Wyvern and Gryphon plushies, as well as the Guardian Cub and Moonkin Hatchling are not available from the in-game Blizzard Store. Additionally, the charity bundle for the Alterac Brew-Pup and mount cannot be purchased through this new feature.
The in-game store arrived just in time for the holidays. Blizzard is having a 50% off sale on certain pets and mounts! [source]
This sale will end January 1, 2014 so while there's still some time, don't wait too long to adopt or gift an adorable Blizzard Store pet!
