Summary
Qwen shipped v0.16.1 for Qwen Code with a core fix for broken tool-use and tool-result handling across failure paths, alongside packaging, build, telemetry, and CLI fixes. The release is a reliability patch aimed at keeping long-running agent sessions from hanging or corrupting state during error recovery.
What changed
Qwen Code v0.16.1 patched tool_use/tool_result failure-path handling and bundled additional fixes across packaging, build stability, telemetry capture, notebook formatting, and CLI behavior.
Why it matters
This is the kind of release that matters more than a flashy feature launch for teams already trying to run agents in production. Fixing tool-call invariants reduces the chance that coding agents hang, lose execution state, or leave sessions in an inconsistent state after a failed action.
