Hi all, yes as @anon61899651 says, there was another thread here where David stated he hoped a testnet would be ready in a couple of weeks “but we will see”.
With the necessary switch to use lazy messaging, as detailed in last week’s update, this week was always a non-starter.
FYI, we had a team catch up today and things seem to be progressing well with the switch to lazy messaging, nothing has popped up that is blocking progress or causing concern…“but we will see” 
Full update on Thursday.
