Summary
Qwen Code released v0.15.11 with bounded session-list metadata reads, pooled buffers, lazy message counting, and a set of CLI and tooling upgrades. The release also adds standalone archive installation, --json-schema for structured headless output, runtime sidecar files for active sessions, and trace ID injection for OpenTelemetry correlation.
What changed
Qwen Code v0.15.11 improved session metadata performance and added headless output, installer, telemetry, and session-runtime updates.
Why it matters
This release tackles the less glamorous bottlenecks that matter when a coding agent graduates from hobby use to long-lived automation. Better session scaling, structured output, and trace correlation all point to a stronger production posture.
