The most popular question since the release of blender 2.40
It’s now put in the modifier stack. http://mediawiki.blender.org/index.php/Manual/PartII/Subsurfaces
Next time first do a search before you post a question.
… exactly what I thought Crouch 
… until I tried it! … to be fair a search on subsurf does not return a useful result on this forum unless you already know you are looking for modifiers - hense why I felt the need to reply and not just let my eyes roll in to the back of my head (again)
Rule number one : search the documentation (hum … the ole rtfm rule 
)
It’s all there and get better all the time
The first thing I did after reading this question was using the search function. When you use ‘subsurf’ as keyword and search the blender general forum you get this as twelfth result: Sub surf toggle button in blender 2.40 alpha 2 This is to be honest even the thread I directly copied the link to the wiki from.
By the way: you are right on using the documentation (indeed do rtfm :P).
