About this tag
The frontier release tag on WindowsForum.com covers Microsoft's audience-based release model for Microsoft 365, where Frontier sits alongside Standard release and Deferred release.

The tag is useful for IT pros planning pilot groups, feature rollout timing and tenant-wide release configuration.
