Release facts

What changed

• MCP configuration: "configure protocol versions and capability discovery" is listed as a feature, along with shared compatibility-aware result conversion across tool surfaces.
• xAI: native xAI batches and files support was added.
• SSO debug routes: /sso/debug routes are now gated behind ENABLE_SSO_DEBUG and are off by default.
• Router and Responses fixes: the notes list provider budget spend counted on every API surface, and Responses stream drops before output now fall back, with truncated streams failing and request_timeout honored.
• Logging and privacy: Sentry output scrubs PII and secrets with a SENTRY_SEND_DEFAULT_PII opt-in, and raw_request is redacted when turn_off_message_logging is set.
• New integration: a Databricks Zerobus trace logging callback was added.

The release page also says Docker images are signed with cosign and gives verification commands using the pinned commit hash or the release tag.
