| community_engine | Improvement | Migrate from plugin to gem. | https://github.com/bborn/communityengine | Learnexa |

| prototype-rails | Not supported in Rails 4.1 & above | This gem will NOT be officially supported on Rails 5.0 and above. jQuery is going to be the default JavaScript library. | https://github.com/rails/prototype-rails#support-for-rails-41-and-above | Learnexa, Performexa & LRS |
| sprockets-rails | Improvement | The asset pipeline is technically no longer a core feature of Rails 4, it has been extracted out of the framework into the sprockets-rails gem. | https://github.com/rails/sprockets-rails | Performexa & LRS |
