What changed

Feature updateNew Copilot Studio agents always get a Microsoft Entra agent identityEvery new Copilot Studio agent now gets a Microsoft Entra Agent ID automatically, and the earlier opt-out has gone. Standard agents get theirs when they're created; GitHub Copilot harness agents get theirs when first published. Admins can see and govern these identities in the Microsoft Entra admin center, for example with Conditional Access. Older agents keep their app registrations until Microsoft migrates them.LicensingCopilot Studio's GitHub Copilot harness bills credits while you buildAgents and apps built on the GitHub Copilot harness use Copilot Credits for building, previewing and testing as well as running, and a Microsoft 365 Copilot licence doesn't cover them. App creation is on by default and gives each maker a developer environment that admins can't stop. Environments with no allocation draw on the tenant's shared credits by default, so set allocations and agent limits.
