Narrative:

During initial climb out; captain flying the loop 4 departure. Socal gave us direct to pevee. I did not see this intersection on our route and informed ATC. We were then instructed to fly heading 150 degrees. ATC queried us as to what SID we were issued. At this point we realized we both had missed the revised segment on our pre departure clearance. SID had been changed to OSHNN3. This is the first time I missed a revised segment (usually very thorough reviewing the clearance). Fatigue was not an issue. Just a matter of being a little too comfortable and that is when something is most likely to come up and bite.
