Release Updates Details
Release Updates (RUs) are a way to roll out new EM features and bug fixes quickly, without waiting for a major release. Release Updates are versioned with a trailing digit indicating the RU version. Note that RUs are cumulative, which means that the most recent RU includes functionality from all previous release updates. Our general recommendation is to apply the most current Release Update as soon as possible.
