# What's New: Week of September 7, 2026

1. **Chat Tests Your Draft**: In the assistant editor, Chat now runs your current unsaved configuration instead of the published version, so you can test your edits before publishing.

2. **Duplicate Simulation Suites**: You can now duplicate an existing [simulation suite](/observability/simulations-overview).

3. **Model Retirement Notices**: You now receive an email the day before a model your assistant uses is retired.
