How do I know which rev board I have?

The Eagel library at viewtopic.php?f=11&t=559 talks about a rev0 and a rev1, the samtec connectors are in different positions.
Was this change made when the caps were moved and the single heatsink was added? or earlier.
From http://elinux.org/Parallella_Hardware#Revisions it seems like very few rev0 board were shipped.
I'm making an io board, would like to get this right.
Thanks,
Tom
