 This controller requires the bin/compatibility_report.php script to be
 run first to create NETAPP_STORAGE/compatibility.serialized. This script
 should be run once an hour to refresh the data.

 To add a new version to the compatibility dashboard:
    1. Add the version to $compatibility_versions array in config.php
    2. Change the COMPAT_DEFAULT_VERSION to the new version in config.php
    3. Add 2 sizes of the wordmark to app/webroot/images/wordmarks
