Bug fixes

If you are upgrading to this image from an earlier released image, the configuration 
changes between these images are not compatible. You will have to reconfigure 
the router following the upgrade.

If the SA 500 you are upgrading is in its factory default state or you do not need to 
retain any of the existing configuration, you can skip the steps for backing up, 
recording, and re-entering your existing configuration settings.

When upgrading the SA 500 follow these steps.
