Announcements to your network
Network → Announcements is your channel to the operators in your network: publish an update once, and see per-operator receipts showing who has opened it and who has acknowledged it.
Publishing and receiptslink
An announcement goes to every operator in your network. Each one records when it was opened, and announcements that ask for acknowledgement record that separately — so “was the new standard communicated” has an answer with names and dates on it, not a guess.
A published announcement can be retracted; retraction removes it from operators’ hubs but keeps your own record of having published and withdrawn it.
