9 - Fixed: memory leak due to bug in `require-from-string`.
10 - Added: for JSON files, append position to end of error message.
14 - Removed: support for loading config path using the `--config` flag. cosmiconfig will not parse command line arguments. Your application can parse command line arguments and pass them to cosmiconfig.

16 - Removed: support for Node versions < 4.
17 - Added: `sync` option.
18 - Fixed: Throw a clear error on getting empty config file.

27 - 2.2.0 included a number of improvements but somehow broke stylelint. The changes were reverted in 2.2.1, to be restored later.
31 - Licensing improvement: switched from `json-parse-helpfulerror` to `parse-json`.

40 - Fixed: swapped `graceful-fs` for regular `fs`, fixing a garbage collection problem.
