The official source reports this update: v2.6.0. Highlights (released Oct 13) Gemini 4 Argon support: Gemini 4 models such as gemini-4-argon stop long answers at a per-request output limit. ADK now resumes these answers automatically, so they come back whole instead of cut off. The resuming is now done by the genai SDK (v1.74.0). ( #1715 , #1759 , #1822 ) Auth: credentials are refreshed and the call retried once after a downstream 401/403. Remote A2A agents accept per-request auth through Config.Auth. ( #1136 , #1150 ) MCP: request-scoped metadata is passed on to MCP tool calls.
