This article documents API changes made in Patch 5.3.0. Previous patch: Patch 5.2.0. Next patch: Patch 5.4.0.

New Features

• You can now control for which specialization you will receive loot from LFR/Quests.
• The number of pet stable pages has increased from 2 to 5 (Increasing the number of slots from 20 to 50).
• Knowledge base and GM tickets now use an embedded web browser to interact with Blizzard's Support website.
  • The embedded browser functionality is encapsulated by the Browser widget type.

Misc Changes

• tradeSkillLink encoding changed significantly. The first four fields were re-arranged, and specialization data was added for Cooking.

Bugs

• If InterfaceOptionsFrame_OpenToCategory(panel) is called before the addon panels list is updated after adding a new panel, the interface options frame will open to another panel. You can work around this behavior by calling the function twice.
