The CAS test environment (cas-test.its.hawaii.edu) has been updated.

As always, we encourage you to test your applications against the updated environment.

This is a somewhat significant update for the Java Servlet Container that the CAS application runs in. The Tomcat 8.0.x track is scheduled for EOL 2018-06-30.

This version supports TLSv1.1 and TLSv1.2. Notably, TLSv1.0 was previously supported, but is not in this update.

  - Comments suggest, "CURL_SSLVERSION_TLSv1_1 (5) or CURL_SSLVERSION_TLSv1_2 (6) only work for PHP versions using curl 7.34 or newer"
Consider deprecating TLSv1.0 in your client configurations if possible
