Many thanks to the Internal Revenue Service for making this information available. Here is their announcement on June 16, 2016. Here is a statement from Public.Resource.Org congratulating the IRS on a job well done.
As I noted in IRS 990 Filing Data (2001 to date):
990* disclosures aren’t detailed enough to pinch but when combined with other data, say leaked data, the results can be remarkable.
It’s up to you to see that public disclosures pinch.
