Just a quick FYI to the list. Due to the splitting out of the javascript files our registration screen is broken if you are installing the CloudBees Free Enterprise Plugins plugin version 1.8 or earlier on Jenkins 1.474.
We hope to have this issue resolved as quickly as possible but for now our recommendation is that if you are interested in the CloudBees Free Enterprise Plugins you should not upgrade to Jenkins 1.474. Thanks -Stephen P.S. it looks like ours is not the only plugin to have been affected by this issue with hetero-lists
