[dependabot]

Bumps github-copilot-sdk from 1.0.2 to 1.0.4.

Release notes

Sourced from github-copilot-sdk's releases.

GitHub Copilot SDK for Java 1.0.4

Installation

⚠️ Artifact versioning plan: Releases of this implementation track releases of the reference implementation. 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. See the corresponding architectural decision record for more information in the docs/adr directory of the source code.

Feature: HTTP request callback support

Register a CopilotRequestHandler on the client to intercept every outbound LLM inference HTTP or WebSocket request — for both BYOK and CAPI — and mutate, replace, or fully forward it. Useful for logging, header injection, model substitution, or custom routing. (#1689, #1775, #1784)

final class MyHandler extends CopilotRequestHandler {
    `@Override`
    protected HttpResponse<InputStream> sendRequest(HttpRequest request, CopilotRequestContext ctx) throws Exception {
        HttpRequest mutated = HttpRequest.newBuilder(request, (n, v) -> true)
                .header("X-Debug-Session", ctx.sessionId() == null ? "none" : ctx.sessionId())
                .build();
        return super.sendRequest(mutated, ctx);
    }
}
CopilotClient client = new CopilotClient(
new CopilotClientOptions().setRequestHandler(new MyHandler()));

Feature: HTTP request callback support

Register a CopilotRequestHandler on the client to intercept every outbound LLM inference HTTP or WebSocket request — for both BYOK and CAPI — and mutate, replace, or fully forward it. Useful for logging, header injection, model substitution, or custom routing. (#1689, #1775, #1784)

    @Override
    protected HttpResponse<InputStream> sendRequest(HttpRequest request, CopilotRequestContext ctx) throws Exception {
        HttpRequest mutated = HttpRequest.newBuilder(request, (n, v) -> true)
                .header("X-Debug-Session", ctx.sessionId() == null ? "none" : ctx.sessionId())
                .build();
        return super.sendRequest(mutated, ctx);
    }
}
CopilotClient client = new CopilotClient(
new CopilotClientOptions().setRequestHandler(new MyHandler()));

Feature: getBearerToken callback for BYOK providers (Managed Identity)

BYOK provider configs now accept a getBearerToken callback so the SDK consumer can resolve bearer tokens (e.g. Azure Managed Identity) on demand. The SDK takes zero Azure SDK dependency — the consumer supplies the callback using any identity library. (#1748)

var provider = new ProviderConfig()
    .setType("openai")
    .setBaseUrl(baseUrl)
    .setGetBearerToken(args -> cred.getToken(ctx).map(AccessToken::getToken).toFuture());

Feature: experimental multi-provider BYOK registry

Register multiple named providers and models on a single session via NamedProviderConfig and ProviderModelConfig. Custom agents can reference provider-qualified model IDs such as "alpha/sonnet". This feature is experimental. (#1718)

Feature: preamble system message section and preserve action

Two new customization options for system message sections. SystemMessageSections.PREAMBLE targets only the identity preamble without affecting its sibling sub-sections (identity and tool_instructions are now documented as section groups). The new preserve action protects an individually-addressable section from a group-level remove. (#1713)

Other changes

• feature: add optional memory configuration (MemoryConfiguration) to session create and resume (#1617)
• feature: defer parameter on tool definitions controls eager vs. lazy tool loading ("auto" or "never") (#1632)
• feature: otlpProtocol telemetry option for configuring OTLP export transport ("http/json" or "http/protobuf") (#1648)
• feature: ModelBilling.tokenPrices surfaced on public SDK types, exposing per-tier pricing and context window limits (#1633)
• feature: CapiSessionOptions.enableWebSocketResponses and ProviderConfig.transport for WebSocket transport control on session create/resume (#1711)
• improvement: call runtime.shutdown during client stop for deterministic OTEL telemetry flush before process cleanup (#1667)
• improvement: rename SystemPromptSections → SystemMessageSections for cross-SDK consistency; old class deprecated with forRemoval=true (#1683)
