Viewing and managing revisions ¶
Go to the Revisions tab to manage revisions. From the Revisions tab, you can view individual revisions, compare revisions, or revert to an earlier revision.
Compare revisions ¶
To see the differences between two revisions, select the revisions and click the Compare selected revisions button, which will take you to the Changes page
On the Changes page, the compare revisions feature displays the revision author and date of each revision. You can select how to view the revisions differences by selecting the layout and view mode, which are Visual Inline/Default or Teaser, Split fields/Raw or Strip Tags, and Unified fields/Raw or Strip Tags.
Visual Inline / Default or Teaser - visually compares the differences as you scroll down the changes page
Split fields / Raw or Strip Tags - displays the text differences in html (Raw) or plain text (Strip tags)
Unified fields / Raw or Strip Tags - displays the changes made (added or removed) in the last revision, but it does not compare the differences
Reverting to a previous revision ¶
The reverting mechanism allows you to set a previous earlier revision as current. Let's say you have revisions {1,2,current}. If you revert to revision #1, a copy of #1 is made and the copy is set as the current revision.
Adding a revision message ¶
The Revision log message field, which is in the Edit tab, allows you to add a message when you create a revision. The message will appear on the Revisions tab along with the revision. It is a good idea to add a meaningful message here whenever you create a node revision so that others (or you, months later) can see why you changed the node and what your changes were, without having to actually view the previous revision.
