+__Improvements__
+- Make ParseUser.current, ParseInstallation.current, ParseConfig.current immutable. This prevents accidently setting to nil. When developers want to make changes, they should make mutable copies, mutate, then save ([#266](https://github.com/parse-community/Parse-Swift/pull/266)), thanks to [Corey Baker](https://github.com/cbaker6).
