One way or another, somebody needs to have recorded the fact that  
"Release 1.0 was built from change 432246."  How you remember that is  
just part of your release process.  Whether you do that with a label  
in your revision control system, by writing it down in a logbook, by  
recording it in file, or by having it tattooed on your release  
engineer's forehead, is up to you.
