Changelog or errata?

[seanlynch]

The boards Michael Kamprath was selling at least a few months ago are rev 1 boards, and I see you're on rev 3. Would it be possible to get a changelog for the different revisions and/or errata for the earlier boards? I just want to make sure I'm not going to run into bugs or confusing differences trying to use a rev 1 board. I notice in particular that you've added an oscillator that's absent on rev 1.
