MagicalRecord v2.3.1

This is primarily a bug fix release to address a host of issues reported in MagicalRecord 2.3.0.

• CocoaPods users who want to use:
  • Shorthand method aliases should add pod 'MagicalRecord/ShorthandMethodAliases' to their Podfile, and run pod update
  • CocoaLumberjack should add pod 'MagicalRecord/CocoaLumberjack' to their Podfile, and run pod update
• Fixed a Core Data multithreading violation when setting a context's working name
• Fixed the check for whether NSPersistentStoreUbiquitousContentNameKey is valid when using iCloud containers
• Attempting to delete a nil managed object, or a managed object not present in the context will do nothing (previously it crashed)
• Add a fix for CocoaLumberjack reporting duplicate definitions of LOG_MAYBE
• Added error logging when the passed value for relatedByAttribute is invalid during a relationship import
• Added more lightweight generics and nullability annotations

MagicalRecord 2.3 is the final 2.x point release of MagicalRecord. It is also the final release that will support the iOS 6 and OS X 10.8 SDKs.

Thanks to everyone who contributed to this release!
