Feature: typed structured outputs for all six SDKs

Provide a JSON Schema, or use an idiomatic typed helper, to have the model return typed, validated output instead of free-form text. (#2590)

const answerSchema = z.object({ value: z.number().int() });
const answer = await session.sendAndWait("What is 19 + 23?", answerSchema);
answer = await session.send_and_wait_typed("What is 19 + 23?", Answer)

Go, Java, C#, and Rust get the same capability via copilot.SendAndWait[Answer], session.sendAndWait(prompt, Answer.class), SendAndWaitAsync<Answer>, and session.send_and_wait_typed(prompt).

Feature: structured JSON-RPC error data in all SDKs

The raw JSON data payload of a JSON-RPC error response can now be inspected in every SDK, so apps can branch on machine-readable error details. (#2664, #2732)

if let Some(data) = error.rpc_data() { println!("{data}"); }
catch (JsonRpcException e) { JsonNode data = e.getData(); }

Feature: experimental connection-global installation confirmation

All six SDKs expose a connection-global handler for the runtime's installations.confirm callback, letting apps present a human review before an MCP or Skill installation proceeds. The handler must return an explicit confirm/decline/cancel decision.

const client = new CopilotClient({
  installationConfirmationHandler: async (request, context) => promptUser(request),
});

Java, Python, Rust, C#, and Go get equivalent options (setInstallationConfirmationHandler, installation_confirmation_handler, with_installation_confirmation_handler, InstallationConfirmationHandler). Java also now exposes typed unions for MCP installation review payloads.
