I am assuming some people may still want to download R31.0.2 (even if just for comparison). It could be useful to add R31.0.2 to:

The previous Early Access releases have been removed and it is recommended to upgrade to the latest JetPack going forward.

Hi dusty_nv

Do you have any news for us, when the first production release of xavier is published?
I do restrain to invest to much time in the developer preview, as the past has shown, that the next Jetpack versions often contain major changes. Therefore waiting is a reasonable option.

Thanks and best regards,
Roger
