The current latest is from 21 June 2005:
  http://unc.dl.sourceforge.net/sourceforge/bonding/bonding.txt

That's the stock channel bonding shipped witht the kernel.  I vaguely
remember reading (probably a year or more ago) that its maximum
througput is achieved with 2 gigabit cards - adding a 3rd card
actually decreases througput.  (Is this still true?)

Also, that there's a different implementation somewhere, not shipped
with the kernel, which is both faster with two cards, and allows
further bandwith increase by adding a 3rd bonded gigabit ethernet
card.  Unfortunately, I can't remember what that project is called,
nor where I read about it.  Does anyone else remember?
