We are happy to announce that all trial registrations will now be issued DOIs (digital object identifiers). For more information, see here.

Version

Motivation: Versioning is important for long-term research data management where metadata and/or files attached to a registration are updated over time. It is used to track any metadata or file changes (e.g., by uploading a new file, changing file metadata, adding or editing metadata) once you have published your registration. Once you edit your published registration, a new version history page of this will be created. If you are at version 1 of your registration, depending on the types of changes you make, you would be asked to publish your draft registration as either version 1.1 (ie. minor change) or version 2.0 (ie. major change). For guidelines on what constitutes a major or minor change, please read below.
