Exclude

• feat: improve Contract PDF exports (c0f45ee82)
• docs: refine contract capability models (444af2237)
• feat: automate bounded daily cache backfill (bbf467fd1)

Rationale

The newsletter should highlight the new audio capabilities and the improved application preview experience, as these are the most significant user-facing updates. Internal infrastructure and features currently disabled (Teams, Plans, Projects) are excluded to maintain focus on available functionality.

Quality Notes

• The update includes a large number of fixes for model preference synchronization, suggesting a focus on multi-device consistency.
• Assistant speech is now fully integrated from the backend streaming layer to the frontend playback UI.
