Where can I get a history of downgrades?

I installed rockbox yesterday but everytime I disconnect from the computer, it goes through a normal firmware ugrade process. Because I used the most current bin file for this rockbox installation, it defaults to that on start up.

Where can I get a list of the firmware updates so I can chose which one to re-rockbox?

Over at ABI.
