Version 4 of the Electronic Release Notification Message Suite Standard offers a significantly simpler way to communicate Release Notifications compared with ERN-3.

Version 4.1 has been developed in response of testing with version 4. It further streamlines the communication of Releases from Release Creators to Release Distributors. The major changes include:

Version 4.1.1 corrects a number of small errors in the XSD (ensuring that Synopsis and Keywords are available on Release and TrackRelease, adding a flag to indicate whether a Contributor is a credited artist, aligning the ResourceRightsController and WorkRightsController composites, enabling the communication of label hierarchies, add the ability to differentiate “covers” from “originals”) and adds rules for the communication of Preview Dates.
