v1.0.7-preview.2

Feature: in-process FFI transport for Rust SDK

The Rust SDK can now host the Copilot runtime as an in-process cdylib instead of spawning a CLI subprocess. Select it with Transport::InProcess or set COPILOT_SDK_DEFAULT_CONNECTION=inprocess. (#1915)

let client = ClientOptions::new()
    .transport(Transport::InProcess)
    .build()?;

The existing Transport::Stdio and Transport::Tcp variants are fully backward-compatible — no breaking changes for current consumers.

For each release of the reference implementation, there may follow a corresponding release of this implementation with the same number as the reference implementation. Release identifiers of the reference implementation are in the form vMaj.Min.Micro. For example v0.1.32. The corresponding maven version for the release will be Maj.Min.Micro-java.N, where Maj, Min and Micro are the corresponding numbers for the reference implementation release, and N is a monotonically increasing sequence number starting with 0 for each release.

v1.0.7-preview.1

Feature: in-process (FFI) transport for the Node.js SDK

The Node.js SDK now supports an experimental in-process transport that hosts the Copilot runtime as a native library via FFI (using [koffi]((koffi.dev/redacted), instead of spawning a child process. This reduces process overhead and eliminates the need for a separate CLI installation when using a bundled native runtime. (#1953)

const connection = RuntimeConnection.forInProcess("/path/to/libcopilot-runtime.so");
const client = new CopilotClient({ runtimeConnection: connection });

Feature: canvasProvider field on session config

All SDKs (Node.js, .NET, Go, Python, Rust) now support an optional canvasProvider field on session create and resume config. This lets host connections supply a stable canvas-provider identity so host-provided canvases restore correctly across cold resume. (#1847)

• TypeScript: canvasProvider: { id: "app:builtin:my-host", name: "My Host" }
• C#: CanvasProvider = new CanvasProviderIdentity { Id = "app:builtin:my-host" }
• Python: canvas_provider=CanvasProviderIdentity(id="app:builtin:my-host")
• Go: CanvasProvider: &CanvasProviderIdentity{Id: "app:builtin:my-host"}

Feature: agent metadata in request handler contexts

Request handler callbacks across all SDKs (Node.js, Python, Go, .NET, Rust, Java) now expose agentId, parentAgentId, and interactionType from LLM inference request-start frames. This lets BYOK/CAPI request handlers identify which agent is making the inference request, and whether it is a subagent call. (#1949)

Other changes

• bugfix: [.NET] fix request-handler forwarding so GET/HEAD requests do not receive an empty content body (#1949)

Feature: request handler context now exposes agent metadata

CopilotRequestContext now includes agentId, parentAgentId, and interactionType fields, giving request handlers visibility into which agent is making an LLM inference call and whether it is a subagent. (#1949)

client.setRequestHandler((context, chain) -> {
    System.out.println("Agent: " + context.getAgentId());
    System.out.println("Parent: " + context.getParentAgentId());
    System.out.println("Interaction: " + context.getInteractionType());
    return chain.apply(context);
});

v1.0.7-preview.0

Feature: enableManagedSettings for enterprise policy enforcement (all SDKs)

Applications can now pass enableManagedSettings when creating or resuming a session to opt the runtime into enterprise managed-settings enforcement (bypass-permissions policy) using the session's gitHubToken. This is purely additive and opt-in — omitting it behaves exactly as before. (#1925)

const session = await client.createSession({
  gitHubToken: "...",
  enableManagedSettings: true,
});

var session = await client.CreateSessionAsync(new SessionConfig
{
    GitHubToken = "...",
    EnableManagedSettings = true,
});

• Python: enable_managed_settings=True kwarg on create_session / resume_session
• Go: EnableManagedSettings: boolPtr(true) on SessionConfig / ResumeSessionConfig
• Rust: .with_enable_managed_settings(true) builder on SessionConfig
• Java: sessionConfig.setEnableManagedSettings(true) on SessionConfig

Fix: deterministic tool schema serialization in Rust SDK ⚠️ Breaking change

The Rust SDK previously used HashMap for Tool.parameters and mcp_servers fields, causing random key ordering in serialized JSON each process startup. This busted the model provider's prompt cache on the system+tools prefix, increasing cost and latency. HashMap is now replaced with IndexMap for these model-visible maps. (#1931)

IndexMap mirrors HashMap's API and is re-exported as github_copilot_sdk::IndexMap — migration is mechanical:

// Before: use std::collections::HashMap;
// After:
use github_copilot_sdk::IndexMap; // same API, deterministic iteration order

Affected public types: Tool.parameters, mcp_servers on SessionConfig / ResumeSessionConfig / CustomAgentConfig, and the tool_parameters / try_tool_parameters return types.
