Use ‘What’s new’ events in Review Manager (RevMan) to describe the changes to the protocol or review since it was last published.

It is essential to select the appropriate option as set out in the following Tables, and to provide as much detail as possible to describe the nature of the change. The reasons for this are:

• To ensure a new citation is applied when appropriate. Note that assigning a new citation generates a new DOI [LINK] and citation in external databases, including PubMed.
• To give readers clear information on what has changed between versions.
• To select the appropriate what’s new events before publication because these cannot be changed after publication (e.g. it is not possible to ‘undo’ a new citation). 

Archie/RevMan guidance: While it is technically possible to enter several ‘What’s New’ events in an updated review, only information about the changes since the last published version should be in the ‘What’s New’ table. ‘What’s New’ events from previously published versions should be moved to the 'History' table in RevMan.
