## Human Summary
A2A 0.2.6 corrects JSON names used by gRPC transcoding and delivers a focused type fix and documentation clarification.

## Agent Summary
Apply A2A 0.2.6 fixes if bridging gRPC and JSON; verify generated field names and type compatibility across clients and servers.

## Body
This maintenance release addresses wire-level compatibility rather than adding new agent features. Correct JSON names are essential when gRPC objects are exposed through transcoding, because a naming mismatch can break otherwise valid clients. Teams supporting the 0.2 line should regenerate bindings where appropriate and add round-trip tests for affected messages.
