Summary
Qwen Code's stable v0.15.6 release focused on the mechanics that keep long-running coding sessions usable, including fixes for reasoning-content preservation, model precedence, directory persistence, and DeepSeek replay behavior. Compared with the earlier nightly framing, the stable release reads as a reliability pass across memory, rewind, compression, and CLI execution paths.
What changed
Qwen Code v0.15.6 shipped stable fixes for reasoning-content handling, model precedence, directory persistence, DeepSeek replay behavior, and SubAgent display stability.
Why it matters
This is less about headline UI features and more about making extended coding-agent sessions hold together under real use. Fixes across rewind, compression, reasoning replay, and path persistence directly affect whether teams can trust the tool in long, iterative workflows.
