 - You must now initialize `CoreDataStack` via a `CoreDataStackFactory`. This will init the stack on a background queue and return to your completion handler on the main queue when finished. This is necessary since adding a persistent store can take an unknown amount of time.
 
-- Rethinking and rewriting of [`CoreDataStack`](http://www.jessesquires.com/JSQCoreDataKit/Classes/CoreDataStack.html). It now has a `mainContext` and a `backgroundContext`. :sunglasses:

 ### New
 
 - New [`CoreDataStackFactory`](http://www.jessesquires.com/JSQCoreDataKit/Structs/CoreDataStackFactory.html) for async stack initialization, as mentioned above. It also support synchronous init if you need it, but this is only recommended for testing.
