We have a new beta release we a major feature and minor fix:

• Shigeru Kobayashi added support running servos on almost all the pins!
• Hernando Barragán added some fixes for building for the Wiring board.

I tested this on a Diecimila and original Arduino. These are the only Arduinos I have, so testing and bug reports on those are very helpful. There are no outstanding bugs that I know of, if I hear of no other bugs, I think this one will be the final release!
