## 3.0.1

April 23, 2019

This is a simple fix so that older versions of org.json can still parse the datafile.

### Bug Fix

We use org.json.JSONArray. Older versions do not support the iterator. In order to ensure that the datafile is still parsable if you use a older version, we changed to use the get method instead of the iterator.
