Pro Tools 8.0.4

I have NOT updated to this version yet but it is available.  Here is the PDF of what it does.  When the 8.0.3 update came out in one studio it did no harm.  In the other it did harm.  So I am hesitant. http://akmedia.digidesign.com/support/docs/Pro_Tools_804_Release_Notes_66729.pdf
