1.0.15

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.

Other changes

• feature: [Java] add native runtime support for darwin-x64 (#​2701)
• feature: [Java] add native runtime support for linuxmusl-x64 (Alpine) (#​2715)

• improvement: [Rust] cut retained runtime-install memory by ~99% (#​2676)
• improvement: [.NET] avoid redundant JSON event materialization and reduce allocations (#​2733)
• improvement: [Node] pin production dependencies to exact versions with a publish-age policy (#​2700)

1.0.15-preview.4

Feature: experimental connection-global installation confirmation

All six SDKs now 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 receives the generated request plus a cancellation signal that fires when the review is retired or the connection closes, and must return an explicit confirm/decline/cancel decision — the SDK never infers approval.

const client = new CopilotClient({
  installationConfirmationHandler: async (request, context) => {
    return await promptUser(request); // "confirm" | "decline" | "cancel"
  },
});

var options = new CopilotClientOptions
{
    InstallationConfirmationHandler = async (request, context) =>
        await PromptUserAsync(request, context.CancellationToken),
};

opts := copilot.ClientOptions{
    InstallationConfirmationHandler: func(ctx context.Context, req *copilot.InstallationConfirmationRequest) (copilot.InstallationConfirmationDecision, error) {
        return promptUser(ctx, req)
    },
}

Java, Python, and Rust get the equivalent setInstallationConfirmationHandler(...), installation_confirmation_handler, and with_installation_confirmation_handler options. Java additionally converts the previously untyped MCP installation/removal review payloads (InstallationConfirmationRequest.review(), McpInstallPlan.transportChoices(), McpInstallationManagementResultOutcome.getOutcome()) into sealed/typed unions, bringing it into line with the other SDKs.

1.0.15-preview.3

Feature: structured JSON-RPC error data in Go, .NET, and Java

Go, .NET, and Java can now inspect the raw JSON data payload of a JSON-RPC error response instead of only its code and message. This mirrors capabilities already available in TypeScript, Python, and Rust, letting apps branch on machine-readable error details. (#​2732)

var rpcErr *copilot.RPCError
if errors.As(err, &rpcErr) {
    fmt.Printf("RPC error %d: %s\n", rpcErr.Code, rpcErr.Message)
}

catch (IOException ex) when (ex.InnerException is RemoteRpcException remote)
{
    Console.Error.WriteLine($"RPC error {remote.ErrorCode}: {remote.Message}");
}

catch (JsonRpcException e) {
    JsonNode data = e.getData();
}

Omitted data and explicit JSON null remain distinguishable in all three APIs, and existing error identity, wrapping, and formatting behavior are unchanged.

Feature: typed structured outputs for all six SDKs

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

class Answer(BaseModel):
    value: int

answer = await session.send_and_wait_typed("What is 19 + 23?", Answer)

var answer = await session.SendAndWaitAsync("What is 19 + 23?");
public sealed record Answer(int Value);

Go, Java, and Rust get the same capability via copilot.SendAndWait[Answer], session.sendAndWait(prompt, Answer.class), and session.send_and_wait_typed(prompt) respectively.

Feature: structured JSON-RPC error data in Rust

copilot::Error now preserves the optional data payload from JSON-RPC errors so callers can inspect machine-readable error details instead of just the message. (#​2664)

if let Some(data) = error.rpc_data() {
    println!("{data}");
}
