Release Updates (RUs) are the agile way to roll out new EM features and bug fixes quickly to customers, so they don’t have to wait for a major release. RUs 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 RU as soon as possible.
