-- Added `@objc` to compile with objective-c.  Thanks to [Junya Yamaguchi](https://github.com/junya100) [(#184)](https://github.com/parse-community/ParseLiveQuery-iOS-OSX/pull/184)
-- Encode Date object with `__type: Date`. Thanks to [anafang](https://github.com/ananfang) [#186](https://github.com/parse-community/ParseLiveQuery-iOS-OSX/pull/186)
+- Fixed issue where no "where" property sent when no constraints where added to a query. This is required by the LiveQuery protocol. 
+- Support for .or queries. Fixes #156, #47, and #85. Allows orQuery to be encoded without throwing. Thanks to [dblythy](https://github.com/dblythy)
