Summary
Qwen Code v0.19.4 shipped on July 1, 2026 with daemon documentation updates and a core change that makes auto-compaction threshold behavior configurable, including Stop hook context usage.
What changed
The v0.19.4 release added configurable auto-compact threshold behavior in the core runtime and refreshed daemon documentation for recent PRs.
Why it matters
Auto-compaction is one of the practical bottlenecks in long-lived coding-agent sessions: too early and the agent loses useful context, too late and sessions become slow or expensive. Making the threshold configurable gives power users and teams a clearer lever for balancing memory, cost, and reliability.
