+
+__Fixes__
+- Remove ParseFile caching due to OS not having a natural way to cache files. Instead, if developers want to access a saved ParseFile, they should check the download directory for the respective file name ([#414](https://github.com/parse-community/Parse-Swift/pull/414)), thanks to [Corey Baker](https://github.com/cbaker6).
