Use ‘What’s new’ events in Review Manager (RevMan) to describe the changes to the protocol or review since it was last published. What’s New events are used to help readers understand the type of change made to a new version of a Cochrane Review (or protocol for a Cochrane Review), such as an amendment, an update, and whether the conclusions have been changed or not. This is to ensure that the history of changes to a review remain with the review as new versions are 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:
...
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 must be in the ‘What’s New’ table. ‘What’s New’ events from previously published versions should be moved to the 'History' table in RevMan.
