Patch 2.4: Interface Options Revamp (src)
Along with Patch 2.4 we will be releasing a revamped in-game Interface Options screen. Most of the systems that interact with the current Interface Options screen have seen some code changes as a result. The new architecture for the system should allow AddOn authors to modify its contents without the taint issues presented by the current Interface Options system.
Additionally, this new system will contain an area for AddOn authors to present their own configuration options to players with a custom heading, subcategories, and frames. I'd like to encourage authors interested in utilizing these features to try the new system on the PTRs before Patch 2.4 is released. Basic details on how to use this system can be found in code comments in Blizzard_InterfaceUI.lua.
Please be aware that AddOns that interact with the Interface Options screen, modify it, or change the way that its options affect other systems within the game will need to be updated with the release of Patch 2.4.
Season 4: No announcement yet (src)
We have made no announcement regarding season 4.
There is more going into patch 2.4 than just the 25 person dungeon and I hope you get a chance to check it all out whenever it is available for testing.
We know it's been a long time and we can't wait to discuss the new patch, but it isn't quite time yet, when time comes we will be happy to share it with all of you.
Europe: Free Character Migration (src)

From: Crushridge, Grim Batol, Outland, Stormscale
To: Burning Steppes, Jaedenar, Vek'nilash
Please note that the migration may be closed at any time should a destination realm's population rise too high.
