chatgpt.com (20260926 → 20260927) — no official release notes in this hop. Not a launch: the client config surface fully hydrated (readable flags 53 → 2271, prior 53 dropped), which is catalog/canary thrash, not net-new product.
Now visible in the flag dump (not live): composer/chat (handoff, centered composer, attachments, code-block previews), Voice/dictation (web/iOS/Android streaming), Imagine/media (DALL·E limits, magic edit, image home banner), Apps/connectors/artifacts, Codex, checkout/upsell, and Android/iOS companion surfaces.
Hashed Statsig: +469 gates, +175 dynamic configs, +283 layers. Plus hashed connector/app ids — counts only; nothing to treat as shipped.
