As many of you have noted, the team has started the deployment to this group. They will be rolling it out slowly throughout the day in small batches. Given the significant nature of the update they're taking the opportunity to watch the installations progress, hence the small batch deployments.
I do hope I've not been over-communicative over the last week or so. One of the challenges of transparency is that expectations get set. This of course sets you all up for disappointment should there be a delay on our side, as there was last night.
I'll be watching this thread and marinating in your excitement all afternoon.
Cheers!
