Those destinations used to send only fixed headers you wrote yourself.\n\n- A `forward_to` entry can now set `auth.google`, including `auth.google.service_account_json`, to sign in with a Google service account.\n\n- When it is set, the exporter fetches Google access headers, caches them per destination, removes any Authorization header and adds the Google ones before sending. Other headers you set are kept.\n\n- `auth.google` requires an https googleapis.com URL and no Authorization header of your own.\n\nSeparately, the gateway's model list now marks models whose metadata has `supports_1m_beta` with `supports1m: true`. `claude-sonnet-4-0`, `claude-sonnet-4-5`, and any config whose environment sets `CLAUDE_CODE_DISABLE_1M_CONTEXT` are left out.\n\n**Why**\n\nYou can send gateway telemetry straight to Google Cloud collectors without making tokens by hand or writing a helper for headers. The model list change lets gateway users see which models offer the 1M context window.\n\n- Area: Gateway\n- Names: `auth.google.service_account_json`, `telemetry.forward_to`\n- Tier: Use it now\n- Useful: 4\/5\n- Signal: 2\/5"}
