Thanks for letting me know, I'll look into this for the next iteration.

I'm not sure, but Sakari definitely went over previous interations and made
various comments,so the series definitely hasn't gone unreviewed!

To be honest I also lost momentum on this but I'll be trying to finalize the
series soon, once the discussion on rx/tx handling has concluded.
