🧠 Microsoft 365 Copilot & Apps

🟢 Just shippedGA 2026-08-21

Turn conversations into code with GitHub Copilot in Microsoft Teams

GitHub Copilot can now be @mentioned inside Teams channels, group chats, meeting chats and 1:1 conversations, where it combines the conversation with repository context to implement a change and open a pull request. The work happens in the Teams thread, so teammates add context and review results in the same place.

Why it matters: Teams becomes a working surface for coding agents, so agent governance conversations now have to cover which repositories a Teams conversation can reach.

🟢 Just shippedGA 2026-08-21

Microsoft Agent Framework - Python 1.15.0

Adds optional A2UI support for agent-generated interfaces with preserved streaming tool-call indices, a MiddlewareFailure fatal signal for function middleware, a process-wide workflow checkpoint registry that supports Cosmos checkpoint state types, and steering, retry and recovery for Foundry hosted agents. Breaking change: OpenTelemetry GenAI semantic-convention support is consolidated into stable and experimental modes with explicit message-event controls.

Why it matters: Teams running Agent Framework agents in production should review the OpenTelemetry consolidation before upgrading, since existing tracing configuration can break.

Why it matters: Copilot memory becomes a retainable and reviewable data location, which changes the answer partners give when customers ask where Copilot's persistent user context lives.

Auto-labeling policy simulation mode in Purview

Before enforcing an auto-labeling policy, admins can run it in simulation mode to identify which items it would label without applying any changes, then review the match results and source distribution to decide whether the policy is ready to enforce.

Why it matters: Label coverage can be validated against real tenant content before enforcement, which removes the main risk in an information-protection rollout.

Insights tab for auto-labeling policies in Purview

The policy details panel gains an Insights tab with an at-a-glance view of an auto-labeling policy's performance. What it shows differs depending on whether the policy is running in simulation or enforcement mode.

Why it matters: Gives admins per-policy evidence of what a label policy is actually catching, without exporting separate reports.
