I recently noticed that the SAM specifications have been updated (September 7, 2011). It would be nice if they listed the differences between versions of the specs and announced changes but I haven't been able to find such a listing. What I ended up doing was converting the pdf to text (via pdftotext) of the recent version and an older version (April 17) and finding the differences that way.
Two main things I noticed - they changed the term "fragment" to "segment" throughout the file. I think this is great since it will help to cut down on confusion with other meanings of the word fragment. I also noticed they added a Barcode (BC) tag.
Another minor thing: the flow signal intensities tag (FZ) is now stored as a byte array of uint16_t instead of a byte array in hex format.
