With changes that affect a targeted set of users, we may notify those users directly.
Changes that are non-critical and do not require action or awareness will not be communicated broadly (even though they may be observable by some users).

Yammer enterprise service communications policy

Yammer adheres to the Microsoft 365 Change Management policy, but does not use Targeted release to roll out some Microsoft 365 updates. Yammer users are subject to A/B feature testing or flighting. This allows Microsoft to test features for stability, performance, and experience improvement across many environments and devices. Users within the same network may have varying experiences due to testing. It is not possible for customers to opt out of A/B testing.
