GitHub Copilot SDK for Java 1.0.8-preview.0

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: per-agent reasoning effort

You can now set a reasoningEffort override on individual custom agents within a session. When omitted, no per-agent override is sent and the backend chooses its default. (#1981)

CustomAgentConfig agent = new CustomAgentConfig()
    .setName("my-agent")
    .setModel("claude-sonnet-4-5")
    .setReasoningEffort("high");

Other changes

• improvement: strongly type internal expAssignments session config field with CopilotExpAssignmentResponse (#2033)
