Back in the day Cub Crafters used to send these out to registered owners by snail mail. I understand that this has changed and there is now no notification of new bulletins to affected owners (happy to be corrected on this but I'm not getting any).

I've solved this with a free subscription to and I now get an alert when there's a change on the suport page. Not as good as it covers any change, not just the ones that affect me but at least I know when to look rather than having to remember.
