Qwen Code v0.25.1-preview.0 Adds Experimental Kubernetes CSI Runtime, M5b Durable Local Outcomes, and Stage H4-H6 Designs

The v0.25.1-preview.0 pre-release, tagged on the Qwen Code GitHub releases page on 06 Oct 2026, introduces an experimental Kubernetes Container Storage Interface (CSI) runtime with a durable worker acknowledgement (ACK), an H3 background Shell and Monitor runtime, M5b durable local Runtime tool outcomes, and a session-directory handoff (W2) for bound Sessions. The same tag lands Stage H5 channel contracts and persistence as a shipped feature, while Stage H4/H5/H6 slice designs and a cross-node EventTransport design land as documentation only.

What the preview introduces

The headline entry is feat(runtime): add experimental Kubernetes CSI runtime and durable worker ACK (#13289). The release tag marks the CSI runtime and the durable worker ACK as experimental; the changelog does not specify the storage path or recovery semantics, so fleet operators running Qwen Code workers as hosted tooling should treat this as preview-stage infrastructure whose contract surface is still being established.

feat(managed-agent): H3 background Shell and Monitor runtime (#13265) ships a background shell runtime; the release title does not describe how the H3 monitor relates to the foreground tool turn or to the CSI runtime, so the body treats it as a standalone shipped background shell runtime.

feat(managed-agent): Make local Runtime tool outcomes durable (M5b) (#13291) ships durable local Runtime tool outcomes in this preview; the release title does not specify the failure modes the durability covers or the state preserved across them, so the durability contract should be treated as preview-stage until the documentation expands.

feat(managed-agent): Stage H5 channel contracts and persistence (#13497) ships the Stage H5 channel contract and persistence layer, while docs(managed-agent): Stage H4/H5/H6 slice designs (#13499) and docs(managed-agent): cross-node EventTransport design (#13500) document slice boundaries for H4/H5/H6 and a design for cross-node EventTransport. The latter two are design documents only and do not establish a shipped cross-node event ordering guarantee on this tag.

feat(managed-agent): let creators change a bound Session's directory (W2) (#13247) ships the W2 directory change; the release title does not describe any active-session rebinding behavior or session-identity preservation guarantees, so the session lifecycle implications of the W2 change should be verified against the documentation before treating it as a generally available capability.

Approval flow and hosted-workspace changes

feat(managed-agent): read bounded approval input previews (#13400) and feat(hosted): show captured inputs in native approval cards (#13407) update the approval experience so approval input previews are bounded and captured inputs appear inside the native approval card.

feat(managed-agent): admit glob in new hosted-workspace /2 profiles (#13166) admits glob in new hosted-workspace /2 profiles; the changelog entry does not state that the older fixed-list syntax is being phased out.

Fixes worth noting before you upgrade

fix(core): pin GIT_TERMINAL_PROMPT in the extension git client (#13454) ships in this preview. fix(cli): never honor memory agent budgets from workspace scope (#13508) keeps memory agent budgets user-scoped. fix(core): key the models.dev catalog under dotted as well as dashed ids (#13299) makes the models.dev catalog resolve identifier forms that include both dotted and dashed segments.

Other relevant commits include fix(managed-agent): serve SSE subscribers from a Condition instead of pinning carriers (#13402), fix(managed-agent): single-flight Hosted Harness attachment creation off the CHM bin monitor (#13403), fix(managed-agent): check the replay before publishing a domain record (#13376), and fix(managed-agent): close the three Critical H0c follow-ups from #13300 (#13355). The Qwen Code release index lists every release tag, the project repository describes the open-source AI coding agent and its multi-platform interfaces, and the Qwen Code docs overview links the Getting Started, User Guide, Developer Guide, and Feature Updates surfaces; the docs overview is a navigation index and does not describe the full hosted-workspace or managed-agent CLI surface.

What to do with this preview

Treat v0.25.1-preview.0 as a canary build. The Kubernetes CSI runtime, M5b durable local tool outcomes, Stage H5 channel contracts, and the W2 session-directory change are preview APIs whose contract surface is still being established. Pin the preview to a canary lane, replay a representative hosted-workspace session, and confirm the new contract before promoting any of these surfaces to production. The Stage H4/H5/H6 slice designs and the cross-node EventTransport design are documentation only, so do not assume cross-node event ordering on this tag. Teams running the managed-agents failover matrix should add the CSI runtime and the M5b durable local outcomes to the canary matrix. Operators tracking CLI upgrade canary drift should add the models.dev dotted/dashed-id fix and the GIT_TERMINAL_PROMPT pin to the canary report. For context on the prior stable tag, the 0.25.0 release story covers the native Advisor tool and the Managed Runtime v2 surface that this preview extends.

The preview is published as a GitHub pre-release tag; the changelog and downloadable assets are available from the GitHub release page.
