You can now view richer information on the edit history of a particular range of content in Google Docs. Simply highlight and right-click on a range of text and select “Show Editors” from the dropdown menu. Here, you can view a list of editors and their latest edit along with time stamps. You’ll also have the option to open the Version History of the document. 

This makes it easier to track edits made by multiple collaborators, giving greater insight into who the recent editors were, what changes were made and when.
