Working in a ChangeSet
As soon as you are in a ChangeSet, all changes made within the ChangeSet to the documents are shown both in the tree view with colored highlighting and in the ChangeSet overview as part of a list.
Changes to documents made by you or another editor in a ChangeSet can only be seen in the respective ChangeSet and can be undone again until the ChangeSet has been published or document changes have been published via “publish directly”, see also Directly publishing / rejecting
