Recommended actions

For this release, we recommend that you review the following checklists and complete the relevant tasks. These checklists identify updates that we have determined as significant for most institutions. We encourage you to review all of the items in the release notes to determine whether there are other items that might require additional action or follow up by your institution.

Administrative actions

These items require immediate action or decisions.


If you are upgrading from an EZproxy version earlier than V6.0, you will need to request an EZproxy Web Services Key (WSKey). To request a WSKey, you will need to have a current, annual subscription. EZproxy moved to the annual subscription model in July 2013, so if you purchased your EZproxy subscription prior to that time, you will need to update.

To purchase an annual subscription, you can request a quote, and you will be provided with a quote and information about how to subscribe. If you are uncertain if your subscription is current, please email

If you have already upgraded to V6.x, your existing WSKey will work with this upgrade.

Review EZproxy and OpenSSL, especially if you are upgrading from a version older than V5.7.44. EZproxy V6.1.x has many security updates that may make previous configurations in your config.txt file unnecessary, and you can remove certain directives after installing V6.1.x.
