AG-UI updates A2A media mapping and Spring AI compatibility boundaries

The October 13 release updates A2A 0.0.7, middleware 0.0.5/0.0.6 and Spring AI 0.0.4, fixing media mapping, clone state and delegated-tool arguments.

Why it matters

Adapter behavior determines whether interfaces preserve media, request state and tool callbacks.

A closer look

A2A uses file bytes/URIs and retained clone state; delegation logging follows debug settings. Spring AI uses maxProtocolVersion and corrected documentation.

Who this is for

AG-UI, A2A and Spring AI integrators
