Old Versions

command M-x vc-annotate to do this. It creates a new buffer to display file's text, colored to show how old each part is. Text colored red is new, blue means old, and intermediate colors indicate intermediate ages. By default, the time scale is 360 days, so that everything more than one year old is shown in blue.

When you give a prefix argument to this command, it uses the minibuffer to read two arguments: which version number to display and annotate (instead of the current file contents), and a stretch factor for the time scale. A stretch factor of 0.1 means that the color range from red to blue spans the past 36 days instead of 360 days. A stretch factor greater than 1 means the color range spans more than a year.
