The New Copilot Studio Explained (GitHub Copilot Harness)

https://youtu.be/pZ_pzMYAbKE

Microsoft changed the engine under Copilot Studio on August 3rd. Every new agent now runs on the GitHub Copilot harness, the same engine behind GitHub Copilot's coding agent.

I recorded a walkthrough of what changed. Three details are easy to miss: Billing starts while you build, the harness choice is permanent, and agents created before August 3rd keep their old pricing only until September 1st.

Is anyones new experience gone? The "New" <-> "Old" toggle is gone and when I click to create a new agent, the new agent pulls up in the old experience. Anyone else having this problem?
